J/MNRAS/407/1657    Rotation velocities of dwarf M stars  (Houdebine, 2010)

Observation and modelling of main-sequence star chromospheres. XIV. Rotation of dM1 stars. Houdebine E.R. <Mon. Not. R. Astron. Soc., 407, 1657-1673 (2010)> =2010MNRAS.407.1657H
ADC_Keywords: Stars, dwarfs ; Rotational velocities Keywords: stars: low-mass - stars: rotation - subdwarfs 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. File Summary:
