Influence of the black hole spin on the chaotic particle dynamics within a dipolar halo
Sankhasubhra Nag, Siddhartha Sinha, Deepika B. Ananda +1
We investigate the role of the spin angular momentum of astrophysical black holes in controlling the special relativistic chaotic dynamics of test particles moving under the influe…
Transonic behaviour and stability analysis of quasi-viscous black hole accretion
Deepika B. Ananda, Soumini Chaudhury, Tapas K. Das +2
Analytical studies of black hole accretion usually presumes the stability of the stationary transonic configuration. Various authors in the past several decades demonstrated the va…
Development of Secular Instability in Different Disc Models of Black Hole Accretion
Sankhasubhra Nag, Deepika B Ananda, Ishita Maity +1
Analytical treatment of black hole accretion generally presumes the stability of the stationary configuration. Various authors in the past several decades demonstrated the validity…
Acoustic geometry through perturbation of mass accretion rate - radial flow in static spacetimes
Deepika B. Ananda, Sourav Bhattacharya, Tapas K. Das
In this work we present an alternative derivation of the general relativistic acoustic analogue geometry by perturbing the mass accretion rate or flux of an ideal fluid flowing rad…
On the realizability of relativistic acoustic geometry under a generalized perturbation scheme for axisymmetric matter flow onto black holes
Deepika B. Ananda, Sourav Bhattacharya, Tapas K. Das
We propose a novel linear perturbation scheme to study the stability properties of the stationary transonic integral solutions for axisymmetric matter flow around astrophysical bla…
