Thin accretion disks around traversable wormholes
Farook Rahaman, Tuhina Manna, Rajibul Shaikh +3
In this paper, we aim to investigate various physical properties and characteristics of radiation emerging from the surface of accretion disks, in a rotating traversable axially sy…
Lyapunov exponent ISCO and Kolmogorov Senai entropy for Kerr Kiselev black hole
Monimala Mondal, Farook Rahaman, Ksh. Newton Singh
Geodesic motion has significant characteristics of space-time. We calculate the principle Lyapunov exponent (LE), which is the inverse of the instability timescale associated with…
A new model for dark matter fluid sphere
Shyam Das, Nayan Sarkar, Monimala Mondal +1
We develop a new model for a spherically symmetric dark matter fluid sphere containing two regions: {\bf (i)} Isotropic inner region with constant density and {\bf (ii)} Anisotropi…
Geodesic stability and Quasi normal modes via Lyapunov exponent for Hayward Black Hole
Monimala Mondal, Parthapratim Pradhan, Farook Rahaman +1
We derive proper-time Lyapunov exponent and coordinate-time Lyapunov exponent for a regular Hayward class of black hole. The proper-time corresponds to and…
Singularity-free nonexotic compact star in gravity
Anil Kumar Yadav, Monimala Mondal, Farook Rahaman
In the present work, we have searched the existence of anisotropic and non-singular compact star in the gravity by taking into account the non-exotic equation of state (Eo…
