On the particle collisions during gravitational collapse of Vaidya spacetimes
Vitalii Vertogradov
The center-of-mass energy can be arbitrarily high in Schwarzschild spacetime if one considers the front collision of two particles, one of which moves along so-called white hole ge…
The Negative Energy in Generalized Vaidya Spacetime
Vitalii Vertogradov
In this paper we consider the negative energy problem in generalized Vaidya spacetime. We consider several models when we have the naked singularity as a result of the gravitationa…
The structure of the generalized Vaidya spacetime containing the eternal naked singularity
Vitalii Vertogradov
In this paper the structure of the generalized Vaidya spacetime when the type-II of the matter field satisfies the equation of the state is investigated. Satisfying all energ…
Non-linearity of Vaidya spacetime and forces in the central naked singularity
Vitalii Vertogradov
In this paper we consider non-linear Vaidya spacetime i.e. the case when the mass function has the non-linear form . We prove that the central na…
