    • Differential equations for relativistic radiating stars. 

      Abebe, Gezahegn Zewdie. (2013)
      We consider radiating spherical stars in general relativity when they are conformally flat, geodesic with shear, and accelerating, expanding and shearing. We study the junction conditions relating the pressure to the ...
    • Lie symmetries of junction conditions for radiating stars. 

      Abebe, Gezahegn Zewdie. (2013-10-31)
      We consider shear-free radiating spherical stars in general relativity. In particular we study the junction condition relating the pressure to the heat flux at the boundary of the star. This is a nonlinear equation in ...
