| dc.description | Spectral synthesis calculations based on three-dimensional stellar atmosphere models are limited by the affordable angular resolution of the radiation field. This hampers an accurate treatment of rotational line broadening. We aim to find a treatment of rotational broadening of a spherical star when the radiation field is only available at a modest number of limb-angles. We apply a combination of analytical considerations of the line-broadening process and numerical tests. We obtain a method which is closely related to classical flux convolution and which performs noticeably better than a previously suggested procedure. It can be applied to rigid as well as differential rotation. | |
