Abstract:
CARMENES is a spectrograph for radial velocity surveys of M dwarfs
with the aim of detecting Earth-mass planets orbiting in the habitable
zones of their host stars. To ensure an optimal use of the CARMENES
guaranteed time observations, in this paper we investigate the
correlation of activity and rotation for approximately 2200 M dwarfs,
ranging in spectral type from M0.0 V to M9.0 V. We present new
high-resolution spectroscopic observations with FEROS, CAFE, and HRS
of approximately 500 M dwarfs. For each new observation, we determined
its radial velocity and measured its Hα activity index and its
rotation velocity. Additionally, we have multiple observations of many
stars to investigate if there are any radial velocity variations due
to multiplicity. The results of our survey confirm that early-M dwarfs
are Hα inactive with low rotational velocities and that late-M
dwarfs are Hα active with very high rotational velocities. The
results of this high-resolution analysis comprise the most extensive
catalogue of rotation and activity in M dwarfs currently available.
Description:
Based on observations made at the Calar Alto Observatory, Spain, the
European Southern Observatory, La Silla, Chile and McDonald
Observatory, USA.
