Abstract:
We investigated almost 500 stars distributed among 193 binary or
multiple systems made of late-F, G-, or early-K primaries and late-K
or M dwarf companion candidates. For all of them, we compiled or
measured coordinates, J-band magnitudes, spectral types, distances,
and proper motions. With these data, we established a sample of 192
physically bound systems. In parallel, we carried out observations
with HERMES/Mercator and obtained high-resolution spectra for the 192
primaries and five secondaries. We used these spectra and the
automatic STEPAR code for deriving precise stellar atmospheric
parameters: Teff, logg, ξ, and chemical abundances for 13 atomic
species, including [Fe/H]. After computing Galactocentric space
velocities for all the primary stars, we performed a kinematic
analysis and classified them in different Galactic populations and
stellar kinematic groups of very different ages, which match our own
metallicity determinations and isochronal age estimations. In
particular, we identified three systems in the halo and 33 systems in
the young Local Association, Ursa Major and Castor moving groups, and
IC 2391 and Hyades Superclusters. We finally studied the
exoplanet-metallicity relation in our 193 primaries and made a list 13
M-dwarf companions with very high metallicity that can be the targets
of new dedicated exoplanet surveys. All in all, our dataset will be of
great help for future works on the accurate determination of
metallicity of M dwarfs.
Description:
First of all, we collected from the literature 193 binary or multiple
system candidates formed by late-F, G-, or early K-type primaries
and late-K or M-type secondaries observable from Calar
Alto, in Southern Spain (δ>-23{deg).
We took high-resolution echelle spectra of 192 primaries and 5
secondaries with HERMES (High Efficiency and Resolution Mercator
Echelle Spectrograph) at the 1.2m Mercator Telescope at the
Observatorio del Roque de los Muchachos (La Palma, Spain) between
January 2010 and December 2017.
We also observed many M-dwarf companions with the low-resolution
optical spectrograph CAFOS at the 2.2m Calar Alto telescope.

Note (3): Notes as follows:
d = Contrary to Simbad, it is not a spectroscopic binary
(Goldin & Makarov, 2007ApJS..173..137G 2007ApJS..173..137G).
e = B component, unresolved by us, is GJ 105 C, an M7V at rho=1.7-3.3-arcsec
(Golimowski et al., 1995ApJ...444L.101G 1995ApJ...444L.101G).
f = BD+50 860C in Simbad.
g = Equatorial coordinates and, therefore, rho and theta are from
raw H-band 2MASS images.
h = B component, unresolved by us, is 9 Aur B, an M2V at rho=4.5-6.3arcsec
(Krisciunas et al., 1993MNRAS.263..781K 1993MNRAS.263..781K).
i = Discoverer code not available in WDS. System taken from
Salim & Gould (2003, Cat. J/ApJ/582/1011).
j = Discoverer code not available in WDS. System taken from
Poveda et al. (2009ApJ...706..343P 2009ApJ...706..343P).
k = CCDM J08162+5705C in Simbad.
l = Pair rejected by proper motions in Caballero (2009A&A...507..251C 2009A&A...507..251C)
(note the wrong WDS identifier in his Table 2), but physical in WDS and
this work.
m = CCDM J14260+3423C in Simbad.
n = Discoverer code not available in WDS. System taken from
Valls-Gabaud (1988LAstr.102..493V 1988LAstr.102..493V).
o = B and C spectral types are switched in Simbad and literature.
p = WDS "D" component, LEP 96, points wrongly to a 2MASS artifact, which
leads to considerable confusion in Simbad.
