R K Anand, H C Yadav

This paper presents power series similarity solutions for spherical shock waves of variable energy propagating in a radiating gas, taking into consideration the Rosseland’s radiative diffusion model. These similarity solutions are obtained for an energy i... see more

Hans-Peter Morsch

The expanding (decaying) universe is discussed in the framework of a local quantum field theory, based on a Lagrangian, in which all fermion operators are coupled to bosons. In this formalism the initial phase of the universe has been explained by creatio... see more

Cas A is the well known supernova remnant and detailed observational data have been accumulated. In particular, recent observations suggest that the element distributions for silicon (Si) and iron (Fe) are very peculiar: Fe locates in front of Si. On the ... see more
