Abstract

This article explains the stellar lifecycle in terms of thermodynamic and quantum mechanical relations. The fate of the stars depending on their initial mass has been discussed on the ground of modern physics. Degeneracy pressure of the fermions like electrons/neutrons stabilizes the compressed remnant of the lower massive star from collapsing into a black at the end of their active life. The fundamental principle of physics has been applied to explain some important and fundamental properties of the stars. Some recent observations, such as the magnetic radiation of the binary white dwarf that helped us to reevaluate our understanding on the present theories of stellar evolution and their constitutive physics has also been addressed in the text.
