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…

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…

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…
