Signatures of Differential Rotation in Solar-type Spectra
Abstract
Bruning (BAAS 38,915,2007) reported on the effects of surface convection on the Fourier signal of differential rotation in the solar spectrum. This paper extends the analysis to a range of parameters such as v sin i, limb darkening, amount of differential rotation, and convective shifts. This grid of models should help establish for observers whether differential rotation is discernible in late-type stellar spectra.
