Rotational velocities of B stars

The rotational velocities of 87 B stars were obtained. The method used is based on the half widths of the HeI 4471 and MgII 4481 lines calibrated on a series of standard stars. Finally the present results were compared with Buscombe’s and Slettebak’s with the following results: V sin i ( Bu ) = 1.4...

Sumario:The rotational velocities of 87 B stars were obtained. The method used is based on the half widths of the HeI 4471 and MgII 4481 lines calibrated on a series of standard stars. Finally the present results were compared with Buscombe’s and Slettebak’s with the following results: V sin i ( Bu ) = 1.42 V sin i (SI) ± 46 km/sec. V sin i ( Bu ) = 1.56 V sin i (Ma-Le) ± 55 km/sec. The complete paper will be published elsewhere.
