Abstract:
We have measured vsini for a selected sample of dM1-type stars. We
give 114 measurements of vsini for 88 different stars, and six upper
detection limits. These are the first measurements of vsini for most
of the stars studied here. This represents the largest sample of vsini
measurements for M dwarfs at a given spectral type. For these
measurements, we used four different spectrographs: HARPS (ESO),
SOPHIE (OHP), ELODIE (OHP) and UVES (ESO). Two of these spectrographs
(HARPS and SOPHIE) are particularly stable in wavelength since they
were designed for exoplanet searches.
