My Research Interests

My Research Interests

My research interests are concerned with computational and mathematical physics and its application in Astrophysics. Numerical and SYMBOLIC tools (FORTRAN and MATHEMATICA) are used to simulate radiation transfer in plasma, modeling the physical parameters of the stellar atmosphere, polytropic and isothermal gas sphere, and stellar nuclear reactions (i.e. Helium Burning).  I applied the above algorithms to probe the physical properties of the plasma inside the stars, spectroscopic and photometric studies will help to give an overview of the physical process that occurred in the media having high density and very high temperature (i.e. White Dwarfs and Neutron Stars). These algorithms are developed in both integer and fractional forms.
