On the Limitations of a Generalized Vaidya Metric
Soumya Chakrabarti, Naresh Dadhich, Chiranjeeb Singha
We prove that there can not be a smooth matching of the Generalized Vaidya metric with an exterior Schwarzschild/Vaidya patch across a finite boundary hypersurface unless the mass…
Buchdahl stars and bounds with cosmological constant
Christian G. Boehmer, Naresh Dadhich, Surajit Das
The Schwarzschild interior solution, when combined with the assumption of a finite central pressure, leads to the well-known Buchdahl bound. This bound establishes an upper limit o…
Relativistic Virial Theorem, Limiting Compactness, and the end state of gravitational collapse
Naresh Dadhich
It is noteworthy that limiting compactness of a static bounded configuration is characterized by a general principle: \textit{one, by equipartition of mass between inside and outsi…
Energetics of Buchdahl stars and the magnetic Penrose process
Sanjar Shaymatov, Naresh Dadhich, Arman Tursunov
Buchdahl star is the most compact object without an event horizon and is an excellent candidate for a black hole mimicker. Unlike black holes, rotating Buchdahl star can be over-ex…
On the equilibrium of the Buchdahl star
Naresh Dadhich
The Buchdahl star is the limiting compactness (which is indicated by sturation of the Buchdahl bound) object without horizon. It is in general defined by the potential felt by radi…
Extending the weak cosmic censorship conjecture to the charged Buchdahl star by employing the gedanken experiments
Sanjar Shaymatov, Naresh Dadhich
In this paper, we wish to investigate the weak cosmic censorship conjecture (WCCC) for the non black hole object, Buchdahl star and test its validity. It turns out that the extrema…
