A class of conformally flat solutions for systems undergoing radiative gravitational collapse
Ranjan Sharma, Shyam Das, Ramesh Tikekar
We present a class of conformally flat solutions of the Einstein's field equations for spherical systems undergoing gravitational collapse accompanied with radial heat flux. The in…
Relativistic Models Of A Class Of Compact Objects
Rumi Deb, Bikash Chandra Paul, Ramesh Tikekar
A class of general relativistic solutions in isotropic spherical polar coordinates are discussed which describe compact stars in hydrostatic equilibrium. The stellar models obtaine…
Non-adiabatic radiative collapse of a relativistic star under different initial conditions
R. Sharma, R. Tikekar
We examine the role of space-time geometry in the non-adiabatic collapse of a star dissipating energy in the form of radial heat flow, studying its evolution under different initia…
Space-time inhomogeneity, anisotropy and gravitational collapse
R. Sharma, R. Tikekar
We investigate the evolution of non-adiabatic collapse of a shear-free spherically symmetric stellar configuration with anisotropic stresses accompanied with radial heat flux. The…
Domain Walls in Kaluza-Klein spacetime
L. K. Patel, Naresh Dadhich, R. Tikekar
Three families of exact solutions of Einstein field equations are found. Each family contains three parameters. Two of these families represent thick domain walls in a five dimensi…
Higher Dimensional Analogue of McVittie Solution
L. K. Patel, R. Tikekar, Naresh Dadhich
A generalization of the McVittie solution, representing spacetime of a mass particle placed in (n+2) dimensional Robertson-Walker universe is reported.
