Shadow of nulllike and timelike naked singularities without photon spheres
Dipanjan Dey, Rajibul Shaikh, Pankaj S. Joshi
In this paper, we derive general conditions for a shadow to occur, without a photon sphere in a spacetime, caused by central nulllike or timelike naked singularities. Using these c…
Constraining modified gravity from tidal phenomena in binary stars
Pritam Banerjee, Debojyoti Garain, Suvankar Paul +2
In beyond-Horndeski theories of gravity, the Vainshtein screening mechanism might only be partially effective inside stellar objects. This results in a modification of the pressure…
Perihelion Precession and Shadows near Blackholes and Naked Singularities
Dipanjan Dey, Rajibul Shaikh, Pankaj S. Joshi
It is now known that, apart from black holes, some naked singularities can also cast shadows which provide their possible observable signatures. We examine the relevant question he…
