On coordinate frames relevant for pulsar physics
Jyotijwal Debnath, Manjari Bagchi
Pulsars can be either isolated or binary (or even in triple) systems. Observational features of pulsars are used to probe various aspects of fundamental physics, including emission…
On the effect of the light bending phenomenon for a pulsar in a binary with a Kerr black hole
Jyotijwal Debnath, Manjari Bagchi
We study the effect of light-bending on the signal of a pulsar in binaries with rotating black hole companions, focusing on stellar mass black holes. We show that the impacts of va…
Astrophysics with Compact Objects: An Indian Perspective, Present Status and Future Vision
Manjari Bagchi, Prasanta Bera, Aru Beri +18
Astrophysical compact objects, viz., white dwarfs, neutron stars, and black holes, are the remnants of stellar deaths at the end of their life cycles. They are ideal testbeds for v…
Quasi-normal f-modes of anisotropic quark stars in full general relativity
Sushovan Mondal, Manjari Bagchi
We investigate f-mode oscillations of anisotropic quark stars within the framework of full general relativity. We consider two different equations of state (EOSs), one is the MIT b…
Thirty Meter Telescope International Observatory Detailed Science Case 2024
Warren Skidmore, Bob Kirshner, David Andersen +168
The Thirty Meter Telescope (TMT) International Observatory (TIO) will be a revolutionary leap forward in astronomical observing capabilities, enabling us to address some of the mos…
f-mode oscillations of anisotropic neutron stars in full general relativity
Sushovan Mondal, Manjari Bagchi
We investigate f-mode oscillations of static anisotropic stable neutron stars within the framework of full general relativity. We present equations governing unperturbed stellar st…
