Dynamics of a thin spherically symmetric radiating shells and collapsed astronomical objects

In ref. [1] it studied the dynamics of a thin dust radiating shell, endowed with spherical symmetry moving in the gravitational field of a central body. We used the General Relativity Theory; in our formalism the shell is a three-dimensional (two space like dimensions, one time like dimension) singu...
