Possibilities and attempts to determine the differential rotation on F-type main-sequence stars
Abstract
The differential rotation upper limits have been determined for 11 F-type stars, mostly from the main sequence, by means of a Fourier transformation analysis of their spectral lines. No indication is found of steep differential rotation for stars of this type, as claimed by Belvedere et al. (1980). The present results are in keeping with those obtained by Gray (1982) for other spectral lines of largely different stars.
