SB2 (797) Eclipsing binary (796). Spectral types F3V + F8V (797) 51 are probably too early for any chromospheric activity, but 51 that needs to be confirmed.

SB2 (794) (794) derived an orbit with P_orb = 47.958 days, e = 0.034 55 +/-0.003 and a mass ratio of 1.2.

Two velocities listed in (549) suggest 56 constant velocity. One velocity in (746) is different by 56 7 km/s from (549). But note that it is not clear that the 56 star listed in (549) is also the star listed in (746). 57 129674 7.46 x-ray source (603) SB1 (603) 1E1440.4+5213, F3V (604), but most likely too early in 57 spectral type to be chromospherically active. 58 131977 HR 5568B 7.93 ? SB2 (647) = Gl 570B, P_orb = 309 days, e = 0.76 (647). Spectral 58 type M1V + M3.5e? (647). Note that Gl 570A [~22" distant] 58 has moderate CaII H & K emission lines [Wilson & Bappu 58 1957, ApJ 125, 661; but see discussion in (647)]. 59 133822 HS Lup 7.7 ? SB2 (770) (677) report photometric variability of Delta b = 0.03 mag 59 and a significantly different photometric period of 7.07 59 days or twice that (14.14 days) compared to the orbital 59 period. Note that P_orb = 17.8, e = 0.2 (770) [see also 59 (712)] and that P_pseudo = 14.24 days according to Hut, 59 1981 [A&A 99, 126]. It is therefore likely that P_rot = 59 2 P_phtm and that the stars are rotating (pseudo) synchro- 59 nously. Spectral type G6-8V + G6-8V (677); (677) rule out 59 the luminosity class of IV originally given by Evans 59 (=770). Improved orbital period in (677). 60 137763 Gl 586 A 6.83 ? SB2 (849) The eccentricity of 0.975 for Gl 586A is the highest value 60 yet found among spectroscopic binaries. At periastron the 60 components are separated by only a few stellar radii 60 (849). P_orb=889.6 days (849), spectral type K1V (380), 60 secondary probably M0V (849) from mass ratio 0.67. 60 vsini(K1) < 3 km/s (849). Gl 856A is the brightest member 60 of the Gliese 856ABC system. A somewhat less precise orbit 60 found earlier by (866) is in agreement with e = 0.975. 61 139777(B) HR 5829(B) 7.31 HK emission (802) maybe (802) B-component of ADS 9696.

G2IV+G0V (868), light variability of 0.01 63 mag suspected by (868) who also noted H and K emission 63 lines. HD 147633 is one of three possible optical 63 identifications of EXO1621-4901. 64 148405 BD+24 3008 8.5 very weak HK (KGS) SB1 (720) K0III, P_orb = 52 days (720). (614) could not find a 64 convincing period in their photometry albeit they observed 64 a full range of 0.107 mag in V. The giant luminosity 64 classification is tentatively (720). 65 151288 9.48 HK emission (747) SB? Two velocities in (549) and one in (747) do NOT exclude 65 velocity variations. Spectral type K7.5Ve (746). 66 153525 7.92 HK emission (747) SB? (747) Two velocities in (747) might indicate short-term 66 variations. HD spectral type K0 (147). 67 154338 EXO1703-3745 9.73 x-ray source (865) ? V amplitude of 0.10 mag and P_phtm ~ 2.7 days (865). The 67 mean colors in (865) indicate a spectral type around G6IV 67 or V or G0III. A low resolution spectrum suggests G0III 67 or IV (865). (501) classified it as G6/8 with no 67 luminosity class. (868) revised their photometric period 67 of 2.7 days to 3.27 days and noted H and K emission lines. 68 154417 V2213 Oph 5.9 HK emission (741) ? HR 6349. IAU velocity standard but velocities from a 68 variety of sources listed in (746) suggest a range of ~30 68 km/s! Mean CaII S-index ~0.27 (776) implies probably too 68 weak an emission to be included in the catalog except the 68 star is a composite binary. Twelve velocities by (372) 68 suggest no variations although the standard deviation is 68 somewhat higher than expected for a constant star. 69 158394/5 SAO 208893 8.25 x-ray source (865) ? (501) classified it as A2V+G(8III). Evidence for weak, but 69 significant, photometric variability (865). H_alpha line 69 is filled in (865).

CaII H & K S-index varied between 0.66 and 0.91, 76 which is about the same value as measured for HD 199178 76 [S-index ~0.87 (776)]. Though no H & K emission lines 76 were reported by (747). Radial velocities of (747) 76 suggest a range of 20 km/s and (747) noted "short-period 76 variation is likely". Spectral type K5V in (746). 77 197010 9.35 x-ray source (604) SB1 (603) Eclipsing binary with P_orb = 0.71 days (784). Large 77 asymmetry of the out-of-eclipse light suggests star-spot 77 activity (784, 785). Both stars are inside their Roche 77 lobes if mass ratio is larger than ~0.6 (784). Orbit 77 needed! (603) lists it as F8 with v sin i = 100 km/s and 77 suggest it to be a W UMa-type binary. This needs to be 77 confirmed. Spectral type more likely G8-9 (Nations et 77 al., BAAS 23, 1414). log L_x = 30.34 erg/s (856). 78 199305 10.03 HK emission (747) SB? One velocity listed in (549) of -8.4 km/s, two measures by 78 (747) of -12 and -17 km/s, however (747) noted "range of 78 15 km/s observed; variation likely". Spectral type M2V 78 listed in (746). 79 200740 HR 8072 6.37 weak HK em. (288) v_r const? (543) Hyades moving group (77). (288) suggests that "HR 8072 79 belongs perhaps to the long-period group RS CVn systems", 79 it shows CaII emission reversals about 25% weaker than the 79 eps UMi-system. Fig. 3 of (288) shows the emission to be 79 quite weak (note that eps UMi has an early type companion 79 which dilutes the emission). (288) gives log F_x = 5.07 79 erg/cm^2/s. Four radial velocity observations by (543) 79 showed apparently no variations, but that needs to be 79 confirmed. 80 201270 7.3 ?

(548) (288) suggested that HR 8964 belongs to the long-period 87 group of RS CVn systems and gives log F_x = 5.64 87 erg/cm^2/s. However, Fig. 3 of (288) shows this emission 87 to be quite weak. (306) lists Dist. = 44 pc. Four radial 87 velocity observations at 66 A/mm by (548) showed 87 apparently no variations, but that needs to be confirmed. 88 222688 6.6 ? composite? (501) The Michigan Catalog (501) gives K1-2III + [G] and 88 includes the comment "composite; is visual double but mag 88 difference varies too great".

X-ray source EXO 99 020528+1454.8. 100 HR Aur 11.43 ? eclipsing (698) Vitrichenko 1970 [Astr. Tsirk. No. 552] classified it as a 100 G0I W Vir-type Cepheid. Light curve is stable at minimum 100 (698) but other parts of the light curve exhibit varia- 100 tions from year to year of ~0.1 mag in V. (V-R) amplitude 100 of almost 0.2 mag due to eclipse (698). Spectral type 100 probably later than K0 (698). Variable H_alpha emission 100 (698). Orbital period is 1.627777 days (702). Spot wave 100 amplitude in V is 0.2: mag (698). Likely a BY Dra system. 101 V532 Cen 12.37 strong HK em. (289) maybe (542) = 3A1431-409. Spectral type G8V-IV (258). Light varia- 101 bility of 0.03-0.25 mag (542). Star 1 is the X-ray source 101 and our "active star" candidate. Star 2 is a Cepheid! 101 (289) reports H_alpha emission, strong CaII H & K emis- 101 sion, high X-ray luminosity L_x <= 8.3*10^33 erg/s and 101 Dist. <= 235+/-30 pc. However, their colors are not con- 101 sistent with the G8 classification derived from spectro- 101 scopy [(B-V) = 1.2 and (U-B) = 1.1 mag]. Therefore, (289) 101 estimated from these colors a K5 dwarf at 100 pc. (542) 101 assumed a distance of 200 pc. (542) also observed a 101 double-peaked H_alpha emission profile (EW ~ 16 A), and 101 estimated M3V-IV(:) for the cooler star. (258) classified 101 it as RS CVn(:)! If V532 Cen is an RS CVn system, then it 101 is unusually highly active (289, 542). Finding chart in 101 (542). 102 V1068 Cyg 10.3 ? eclipsing (227) Orbital period P_orb = 42.7 days (553). Spectral type 102 B5-A5/G8III-II (227). Light variation of ~0.10 mag seen 102 by (227). (227) suggested it as a long period RS CVn 102 system. (553) found the correct period, the older GCVS 102 1969 periods are wrong. (258) [= GCVS 1985] listed it as 102 B9/G8III-II and classified it as an RS CVn(:) system. 103 V530 Ori 9.87 ?
