Gravitational collapse due to dark matter and dark energy in the brane world scenario
Soma Nath, Subenoy Chakraborty, Ujjal Debnath
Gravitational collapse of FRW brane world embedded in a conformaly flat bulk is considered for matter cloud consists of dark matter and dark energy with equation of state $(…
Adiabatic Particle Production with Decaying and Anisotropic Universe
Sisir Bhanja, Subenoy Chakraborty, Ujjal Debnath
Here we study an anisotropic model of the universe with constant energy per particle. A decaying cosmological constant and particle production in an adiabatic process are considere…
Role of Pressure in Quasi-Spherical Gravitational Collapse
Subenoy Chakraborty, Sanjukta Chakraborty, Ujjal Debnath
We study quasi-spherical Szekeres space-time (which possess no killing vectors) for perfect fluid, matter with tangential stress only and matter with anisotropic pressure respectiv…
Quasi-spherical gravitational collapse and the role of initial data, anisotropy and inhomogeneity
Subenoy Chakraborty, Ujjal Debnath
In this paper, the role of anisotropy and inhomogeneity has been studied in quasi-spherical gravitational collapse. Also the role of initial data has been investigated in character…
