Pleiades low-mass stars rotational velocities

The differential rotational broadening has been resolved for all the stars in our sample. These results, combined with previously published measurements, provide a complete and unbiased rotation data set for stars in the mass range from 0.6 to 1.2M_{sun}_.

Applying a numerical inversion technique on the vsini distributions, we derive the distributions of equatorial velocities for low-mass Pleiades members. We find that half of the Pleiades dwarfs with a mass between 0.6 to 1M_{sun}_ have rotation rates lower than 10km/s.
