Rotational velocities of F dwarfs: application of the Fourier-Bessel transformation method.

GROOT P.J., PITERS A.J.M. and VAN PARADIJS J.

Abstract (from CDS):

Projected rotational velocities are presented for 178 bright dwarf stars (V<7) with spectral types in the range A8 till G2. These rotational velocities have been determined by Fourier-Bessel transformation of the line profiles of six Fe I absorption lines in a 50 A wide range centered on 6250A. Rotational velocities of stars with suspected velocities of more than 40km/s were also determined by fitting the whole spectral range with a profile of a slowly rotating star of the same spectral type that has been convolved with a rotation profile. The agreement between the results obtained with these two methods is very good.
