Abstract: One of the reasons that the new stellar limb darkening linear empirical law ismore accurate can be explained from aspect of geometry. The LTE generalizationof the new law agrees to the observation results of the Sun and the Antares well.The condition under which two limb darkening zero order approximations(UD andFDD) could be applied is summarized in the paper. -
