5193 Large bibliography in SIMBAD refers in fact to the bright Be star 5193 HR 5193; some of the entries do not even refer to it by that name but 5193 as {mu} Cen, etc. 21989 Barium star, discovered by MacConnell, Frye & Upgren 21989 (1972AJ.....77..384M), and classified as such by Houk & Cowley (1975, 21989 Cat. ). We had opportunities to make only three radial-velocity 21989 measurements, but they are all mutually discordant and thereby confirm 21989 positively that it is an SB, as barium stars are expected to be. 23332 Metal-weak giant, recognized first by Bidelman & MacConnell (1973, 23332 Cat. ) and classified as such in the revision of the HD 23332 Catalogue (Houk & Cowley 1975, Cat. ). 26046 vsini=6.9+/-1.1km/s. 26615 Faint companion seen at 3 arcsec, 340{deg}; previously recorded by 26615 Rossiter (1955POMic..11....1R). 26777 The 1970 SIMBAD bibliographic entry appears to refer to a different star 26777 (38 Ori). 28753 See (1898) 37, ADS 3282 A, companion 11.6mag, 13arcsec, 34{deg}. 31341 Discovered to be a `marginal barium star' by MacConnell et al. 31341 (1972AJ.....77..384M) and repeatedly reaffirmed as such since. The 31341 barium character was not recognized in the revision of the HD Catalogue 31341 (Houk, 1982, Cat. ) and led to the assignment of a luminosity 31341 class that is too bright. Seven radial-velocity observations reasonably 31341 distributed over an interval of more than six years show no significant 31341 variation, and one measurement by Beavers & Eitter (1986ApJS...62..147B) 31341 accords well with our value. The star has a 10.7-mag visual companion 31341 (cf. Table 8) whose velocity we have measured and which has proved to be 31341 a spectroscopic binary with a {gamma}-velocity identical with the mean 31341 radial velocity of the visual primary. 31484 Faint companion seen at 22 arcsec, 276{deg}. 33978 Discovered early in our observations to be a short-period spectroscopic 33978 binary system; with the assistance of ESO observers we have been able to 33978 establish a good double-lined orbit (described in Paper XVII, Griffin 33978 2006, Cat. ) with a period of some 10d. The folded 33978 light-curve (ESA 1997, vol. 12, p. A100) of the Hipparcos photometry 33978 shows a variation, doubtless arising from ellipticity of the primary 33978 star, at exactly half the orbital period. That was recognized by Koen, 33978 Laney & van Wyk (2002MNRAS.335..223K), who also discovered the 33978 corresponding radial-velocity variations. The system has received the 33978 variable-star designation VV Lep. It is also a visual double star, 33978 van den Bos (1928, Ann. Leiden Obs. 14, Part 4) 81, ADS 3804; the 33978 companion has been estimated at 13 mag and is only 2 arcsec away from 33978 the primary. 34659 Double star, Coo 29 (Innes, 1905, Ann. Cape Obs., 2, Part 4), ADS 3892, 34659 with almost equal K-dwarf components 4 arcsec apart, both measured by us 34659 (cf. Tables 4 and 8) and found to have similar radial velocities. 34659 Hipparcos found substantial photometric variations; the period and type 34659 of variability were not determined by Hipparcos itself, but in the Inf. 34659 Bull. Variable Stars name-list (Kazarovets et al., 1999IBVS.4659....1K) 34659 in which it was designated VW Col it is listed as type EA (`Algol type 34659 eclipsing variables'). A plot of its (Hp) magnitude against time looks 34659 most unusual: there is an upper limit to the envelope at about 9.2mag, 34659 but the majority of points are not clustered just near it as might be 34659 expected for an Algol system - the distribution thins out only gradually 34659 towards fainter magnitudes, with the faintest one being at 11.6mag and 34659 having only a small error bar. Especially in the context of the apparent 34659 constancy of radial velocity, the photometry presents an interesting 34659 puzzle. If any periodicity could be found, it would be likely to have 34659 been reported by Koen & Eyer (2002, Cat. ). 35164 ADS 3954 C, distant optical companion at 58 arcsec, 104{deg} to HR 1771 35164 (which is called 41 Lep in ADS; it is in Lepus, but the RA is between 35164 those of 7 and 8 Lep and the numbering in that constellation goes only 35164 to 19). 35993 Barium star, discovered by MacConnell et al. (1972AJ.....77..384M), 35993 classified as such by Houk & Smith-Moore (1988, Cat. ), and 35993 duly found by us to be a spectroscopic binary, whose orbit is given in 35993 Paper XVII (Griffin 2006, Cat. ). 36745 Very close visual binary, ADS 4153, not resolved in our observations; 36745 visual orbit very eccentric, P~70yr, periastron passage just recently. 37730 Visual companion (cf. Table 8) is a binary of short period and large 37730 amplitude; it has a vsini of 10+/-3km/s. Regrettably the authors have 37730 had no opportunity to determine the orbit. 40293 Classified M3.5 III by Frishberg (1975SvAL....1..166F); presumably 40293 misidentified. 41023 IDS lists 13-mag companion (Herschel 1847, p. 186) at 21.2-arcsec, 41023 354{deg}. 44627 Small-amplitude variable star AB Pic, possibly of BY Dra type; now known 44627 to possess a low-mass companion (Chauvin et al., 2005A&A...438L..29C). 47519 Very blue (F6 V), feeble radial-velocity dip, vsini=7.5+/-2.5km/s. All 47519 velocities rather uncertain. 47951 M giant with seemingly irregular photometric variations; V446 Car. 90167 Discovered to be a `marginal barium star' by MacConnell et al. 90167 (1972AJ.....77..384M) and repeatedly reaffirmed as such since. The 90167 barium character was not recognized in the revision of the HD Catalogue 90167 (Houk & Smith-Moore 1988, Cat. ) and led to the assignment of 90167 a luminosity class that is too bright. Three radial-velocity 90167 observations in different years show no discordance. 91064 ADS 7806 A; 13-mag companion (Herschel 1847, p. 203) at 14-arcsec, 91064 100{deg}. 92789 vsini=10.3+/-0.7km/s. 92830 , 92920. Although the stars are only 10-arcmin apart and have similar 92830 radial velocities, they are unrelated, having quite different 92830 spectroscopic parallaxes and proper motions. 92920 See 92830. 94428 IDS lists 15-mag companion (Donner, 1955, Publ. Univ. Michigan Obs., 94428 11, 1) at 5.7-arcsec, 300{deg}. 96768B vsini=12+/-5km/s. 96873 IDS lists 11.5-mag companion (van den Bos, 1951, Union Obs. Circ., 6, 11) 96873 at 0.5-arcsec, 222{deg}. 99426 Particularly faint, and early type; all observations rather poor. 99552 IDS lists 15-mag companion (van den Bos, 1929, Union Obs. Circ., 3, 59) 99552 at 3.2-arcsec, 16{deg}. 111680 Identified as a `strong-CN' star by Houk (1982, Cat. ). Adopted 111680 by Keenan (Keenan & Yorka, 1988BICDS..35...37K; Keenan & McNeil, 111680 1989, Cat. ) as an MK standard star of type K1-III Fe 1, 111680 although he had previously (Keenan, 1987PASP...99..713K) noted it as 111680 K1 III CN 1 and remarked (Keenan, Yorka & Wilson, 1987PASP...99..629K) 111680 that for only a few of the Houk strong-CN stars is an abnormal strength 111680 of the iron lines so noticeable that they need to be distinguished by 111680 positive indices. 112402 Early type; feeble radial-velocity dips, so poor accuracy. 114483 vsini=14.1+/-0.6km/s; velocities therefore rather poor. 116463 IDS lists 12.5-mag companion (van den Bos 1930) at 8.4-arcsec, 10{deg}. 116858 , 116920. HD 116858 long recognized as a nearby dwarf, Gliese 511 116858 (Gliese, 1969VeARI..22....1G). Van den Bergh (1958AJ.....63..246V) 116858 pointed out, from the entries in the Yale Zone Catalogues, the 116858 common-proper-motion companion HD 116920 about 5 arcmin distant, which 116858 he reported as having also a similar radial velocity, as indeed we 116858 confirm here. 116920 See 116858 117987 Known as a `proper-motion star', {mu} almost 0.6-arcsec per annum. 118597 Companion at 25-arcsec, 127{deg}, with no dip in radial-velocity trace, 118597 presumably early type. 119188B vsini=10+/-4km/s. 119321 Crifo et al. (1992A&A...258..116C) pointed out an error in the SAO proper 119321 motion. 120013 ADS 9024, wide optical double (Hough, 1894, Astron. Nachr. 135, 281), 120013 companion approx. 18-arcsec, 171{deg}. 120304 Type B7-B9, evidently misidentified (Sundman, Loden & Nordstrom, 120304 1974, cat. ). 120571 Discovered to be a `certain barium star' by MacConnell et al. 120571 (1972AJ.....77..384M) and repeatedly reaffirmed as such since. The 120571 barium character was not recognized in the revision of the HD Catalogue 120571 (Houk & Smith-Moore, 1988, Cat. ) and led to the assignment of 120571 a luminosity class that is too bright. Our two radial-velocity 120571 observations show no change but were taken only one year apart; two 120571 measurements by Catchpole, Robertson & Warren (1977MNRAS.181..391C) 120571 show a 14km/s mutual discordance that may be significant. 121552 IDS lists 11.7-mag companion (van den Bos 1931, Union Obs. Circ., 3, 183) 121552 at 1.7-arcsec, 176{deg}. 122055 Discovered by Hipparcos to be a photometric variable, now designated 122055 MQ Vir, type LB (`slow irregular variable of late spectral type'). 122055 Koen & Eyer (2002, Cat. ) claimed to find a 120-d 122055 periodicity that had escaped Hipparcos. vsini=8.9+/-1.1km/s. 125169 Wide visual double (Herschel 1847, p. 216), 11.9-mag companion at 125169 18-arcsec, 23{deg}. 125268 The SIMBAD bibliographic entry appears to refer to a different star 125268 (HD 122563). 125493 Rossiter (1955POMic..11....1R) discovered a very faint companion at 125493 4-arcsec, 82{deg}. 176772 Feeble radial-velocity dip, weaker than would normally correspond to its 176772 colour index and spectral type. Velocities uncertain. 182073 Very weak and unquantifiably wide radial-velocity dip. 184626 (HD 184650 = HD 184626B) vsini=17+/-3km/s. 186043 See (1898) listed a 12-mag companion at about 10-arcsec, 130{deg}. There 186043 is a brighter star (HD 186032, 8.26mag, A1V) at 135-arcsec, 325{deg}. 186058 Wilhelmina Fleming (Pickering & Fleming, 1896ApJ.....4..142P) noted this 186058 star as type B2p with H in emission, but it has since appeared to be a 186058 normal K star. Hoffleit (1975MNSSA..34...81H) managed to retrieve the 186058 very plate which was the basis for Fleming's classification and found it 186058 to show almost nothing. 188202 Type O9.5 III (Peton et al., 1972, Cat. ), evidently 188202 misidentified. 189855 Several mentions in the literature arising from its adoption as a 189855 photometric standard in one of the Cape `E regions' by Cousins & Stoy 189855 (1962RGOB...49....3C). 194327 Close (0.3-arcsec) and nearly equal visual double star (Innes, 1948, 194327 Union Obs. Circ., 5, 193 ), motion 2{deg} per year. 195477 Faint companion seen at 17-arcsec, 116{deg}. 195660 Faint companion seen at 47-arcsec, 59{deg}. 197890 Variable star BO Mic, `Speedy Mic', very rapid rotation, very large 197890 literature (more than 60 items in SIMBAD since 1992 when its rotational 197890 velocity was first recognized). See text, end of Section 5. 199242 Listed as a subdwarf by Carney (1978AJ.....83.1087C). 200382 Much too blue for its classification of K1/K2 III; listed by Nordstrom 200382 et al. (2004, Cat. ) as having M_V_=6.18mag. 210009 Faint companion seen at 42-arcsec, 350{deg}. 218109 Very faint companion seen at 17-arcsec, 327{deg}. 222899 May be SB2 - discrepancies in width and depth of dip as well as in 222899 velocity. 223614 Very unequal Hipparcos double star; 12.3-mag companion at 223614 0.43-arcsec, 184{deg}. 223646 Discovered as a barium star in the revision of the HD Catalogue by 223646 Houk & Cowley (1975, Cat. ). Our radial velocities are modestly 223646 discordant but represent only two epochs, so in the spirit of the third 223646 paragraph of Section 4 above we can note the object only as a `possible 223646 SB', although in the light of the barium nature of the star the 223646 discordance could be seen as confirming the expectation that it is a 223646 spectroscopic binary. 223845 Faint companion seen at 43-arcsec, 339{deg}.
