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…
Maximum Force in Modified Gravity Theories
John D. Barrow, Naresh Dadhich
We investigate the existence and nature of classical maximum force bound between two black holes with touching horizons. Besides general relativity, the maximum force bound is inde…
Dust collapse in 4D Einstein-Gauss-Bonnet gravity
Daniele Malafarina, Bobir Toshmatov, Naresh Dadhich
We consider gravitational collapse in the recently proposed 4D limit of Einstein-Gauss-Bonnet gravity. We show that for collapse of a sphere made of homogeneous dust the process is…
Supermassive black holes as possible sources of ultra high energy cosmic rays
Arman Tursunov, Zdeněk Stuchlík, Martin Kološ +2
Production and acceleration mechanisms of ultra-high-energy cosmic rays (UHECRs) of energy eV, clearly beyond the GZK-cutoff limit remain unclear that points to exotic na…
Limits on stellar structures in Lovelock theories of gravity
Sumanta Chakraborty, Naresh Dadhich
We study the bound on the compactness of a stellar object in pure Lovelock theories of arbitrary order in arbitrary spacetime dimensions, involving electromagnetic field. The bound…
On causal structure of -Einstein-Gauss-Bonnet black hole
Naresh Dadhich
The recently proposed effective equation of motion for the - Einstein-Gauss-Bonnet gravity admits a static black hole solution that has, like the Rissner-Nordström charged blac…
