Abstract

Structures of Newtonian super-massive stars are calculated with the opacity for Comptor effect K0/(1 + αT), where K0=0.21(1 +X and α=2.2×10-9K-1. The track of the Main-Sequence is turned right in the upper part of the HR diagram. Mass loss will occur in a Main-Sequence stage for a star with mass larger than a critical mass. The cause of mass loss and the expansion of the radius is continuum radiation pressure. The critical mass for mass loss is 1.02×106M for a Population I star, and 1.23×105M for Population III star. Mass loss rates expected in these stars are 3.3×10-3 and 4.0×10-3M yr-1, respectively.
