The rotational velocities of a sample of Herbig Ae/Be stars

Rotational velocity estimates are presented for 15 Herbig Ae/Be stars. Those objects with nominal optical spectral types between B5 and A0 show a frequency distribution of v sin i values significantly different from that of normal Be stars in this spectral type range; the Herbig emission stars must...

Description
Summary:Rotational velocity estimates are presented for 15 Herbig Ae/Be stars. Those objects with nominal optical spectral types between B5 and A0 show a frequency distribution of v sin i values significantly different from that of normal Be stars in this spectral type range; the Herbig emission stars must have significantly smaller intrinsic rotational velocities. Herbig emission stars of types B0-B5 cannot be distinguished from normal Be stars on the basis of rotational velocity alone.
