Rotation of Evolving A and F Stars
Listed in IVOA Registry (Virtual Observatory)
The authors have studied a vertical strip in the HR diagram covering the range of spectral types A5 through F9.
Description
Rotational velocities for a total of 579 stars of all luminosity classes were accumulated. HR number, rotational velocity v sin(i), (b-y) index, m1, c1, reference and group are given.
The rotational velocities are also included in the compilation by Uesugi and Fukuda (catalog <III/63>) Introduction: Approximately 360 stars from the Bright Star Catalogue (Hoffleit, 1964) were observed with the coude spectrograph on the 84 in. telescope at Kitt Peak National Observatory at a dispersion of 13.6 A/mm. A few stars were observed with the coude spectrograph on the 100 in. telescope at Mt. Wilson.

The remainder were obtained from the published material that the authors considered to provide reliable rotational velocities. The values given here generally agree with the mean v sin(i) found in the literature to within 15%. The method for determining the rotational velocities is somewhat different from the usual approach.
A grid of standard stars, judged from their line-widths to have small rotation, was chosen. Five sections of their spectra traced on the microphotometer at Harvard College Observatory were mathematically broadened according to the usual formula to provide a grid of spectra with which observed spectra could be compared to obtain the rotational velocity.
