Rotational Velocities of Stars in IC 4665
Abstract
The B4-B7 V stars in the open cluster IC 4665 have an extremely small mean rotational velocity compared with the Pleiades or field stars, while the mean rotational velocities of the B8-A3 V stars are the same as for the Pleiades. It is suggested that tidal interactions in binary systems, which are frequent in IC 4665 but not in the Pleiades, cause the low mean rotational velocities in the former cluster.
