    • Abstract


      During its active lifetime, a star burns its nuclear fuel, andgravitation is held off by the pressure of the heated gas. Gravityshould take over once this fuel is exhausted unless someother agency saves the star from such a fate. Low mass starsfind peace as ‘white dwarfs’ when the electrons settle intoa Fermi degenerate phase where the pressure of degenerateelectrons balance the gravitational pressure.
