Evidence for a bimodal distribution of rotation rates among B-stars (New Paper)

1 Dec

Screen shot 2013-02-08 at 12.40.44 PMThe rotation rates of 335 apparently single early B-type stars in the Tarantula nebula  show a bimodal distribution, resembling that found for late-B and early-A type stars.

The origin of the bimodality remains unclear, although it is likely that magentic braking and binary interaction play a role.
