Abstract:
Present and future high-precision radial-velocity spectrometers
dedicated to the discovery of low-mass planets orbiting low-mass
dwarfs need to focus on the best selected stars to make an efficient
use of telescope time. In the framework of the preparation of the
SPIRou Input Catalogue (SPIC), the CoolSnap program aims at screening
M dwarfs in the solar neighbourhood against binarity, rapid rotation,
activity, etc. To optimize the selection, this paper describes the
methods used to compute effective temperature, metallicity, projected
rotation velocity of a large sample of 440 M dwarfs observed in the
visible with the high-resolution spectropolarimeter Echelle
SpectroPolArimetric Device for the ObservatioN of Stars (ESPaDOnS) at
Canada-France-Hawaii Telescope. It also summarizes known and newly
discovered spectroscopic binaries, and stars known to belong to visual
multiple systems. A calibration of the projected rotation velocity
versus measured line widths for M dwarfs observed by the ESPaDOnS
spectropolarimeter is derived, and the resulting values are compared
to equatorial rotation velocities deduced from rotation periods and
radii. A comparison of the derived effective temperatures and
metallicities with literature values is also conducted. Finally, the
radial-velocity uncertainty of each star in the sample is estimated,
to narrow down the selection of stars to be included into the SPIC.
Description:
Observations were conducted with the ESPaDOnS spectropolarimeter at
the CFHT 3.6m telescope on top of Maunakea (Hawaii), which provides a
wide optical range from 367 to 1050nm in a single shot at a resolving
power of 65000 (polarimetry) or 68000 (pure spectroscopy in the
so-called star plus sky mode, with one fibre on the target and one on
the sky ("S+S").
In addition to our own measurements, we searched the ESPaDOnS archive
in polarization mode at the Canadian Astronomy Data Center (CADC) from
2005 to 2015 (inclusively) and found 839 spectra for 71 additional M
dwarfs.
Finally, we also searched the ESPaDOnS archives for stars observed in
the purely spectroscopic S+S mode. We found 785 spectra for 255
additional stars, raising the total sample of M dwarfs observed with
ESPaDOnS to 440.
Spectra of stars belonging to the complementary samples (polarimetric
and spectroscopic) have generally been published, but we reanalyse
them to derive their effective temperature, metallicity, and projected
rotation velocity in a consistent way.
