Gravitational collapse of anisotropic stars
Shyam Das, Bikash Chandra Paul, Ranjan Sharma
We study the gravitational collapse of a spherically symmetric anisotropic relativistic star within Einstein theory of gravity making use of one of our recently developed collapsin…
Tidal love number of a static spherically symmetric anisotropic compact star
Shyam Das, Bikram Keshari Parida, Ranjan Sharma
Tidal deformability of a coalescing neutron star subjected to an external tidal field plays an important role in our probe for the structure and properties of compact stars. In par…
Electromagnetic and anisotropic extension of a plethora of well-known solutions describing relativistic compact objects
K. Komathiraj, Ranjan Sharma
We demonstrate a technique to generate new class of exact solutions to the Einstein-Maxwell system describing a static spherically symmetric relativistic star with anisotropic matt…
Revisiting Vaidya-Tikekar stellar model in the linear regime
Ranjan Sharma, Shyam Das, Megan Govender +1
We obtain a new class of solutions by revisiting the Vaidya-Tikekar stellar model in the linear regime. Making use of the Vaidya and Tikekar metric ansatz [J. Astrophys. Astron. {\…
Anisotropic generalization of Vaidya-Tikekar superdense star
S. Thirukkanesh, Ranjan Sharma, Sunil D. Maharaj
We study superdense relativistic stars with anisotropic matter distributions with spheroidal spatial hypersurfaces. We propose a methodology to make an anisotropic generalization o…
An electromagnetic extension of the Schwarzschild interior solution and the corresponding Buchdahl limit
Ranjan Sharma, Naresh Dadhich, Shyam Das +1
We wish to construct a model for charged star as a generalization of the uniform density Schwarzschild interior solution. We employ the Vaidya and Tikekar ansatz [{\it Astrophys. A…
