A different approach to anisotropic spherical collapse with shear and heat radiation

摘要: In order to study the type of collapse mentioned in title, we introduce a physically meaningful object, called horizon function. It directly enters expressions for many stellar characteristics. The main junction equation, which governs collapse, transforms into Riccati equation with simple coefficients We integrate this geodesic case. same is done general case when one or another vanish. shown how build classes star models formulation problem and solutions are given.
