A Study of Stellar Model with Cramer's Opacity by using Runge Kutta Method with Programming C

Abstract

Bin Masud A

This paper, I have made an investigation on a stellar model with Kramer’s Opacity and negligible abundance of heavy elements. I have determined the structure of a star with mass 2.5⊗ M, i.e., the physical variables like pressure, density, temperature and luminosity at different interior points of the star. Discussed about some equation of structure, mechanism of energy production in a star and energy transports in stellar interior and then I solved radiative envelope and convective core by the matching or fitting point method by C Programming language.
