The secular evolution of the purely general relativistic low angular momentum accretion flow
around a spinning black hole is shown to exhibit hysteresis effects. This confirms that a …

We analyze the properties of a polytropic fluid that is radially accreted into a Schwarzschild
black hole. The case where the adiabatic index γ lies in the range of $1\lt\gamma\leqslant …

Using mathematical formalism borrowed from dynamical systems theory, a complete
analytical investigation of the critical behaviour of stationary flows in low angular momentum …

This work makes the first ever attempt to understand the influence of the black hole
background spacetime in determining the fundamental properties of the embedded …

In black hole evaporation process, the mass of the hole anti-correlates with the Hawking
temperature. This indicates that the smaller holes have higher surface gravity. For analogue …

We introduce a novel formalism to investigate the role of the spin angular momentum of
astrophysical black holes in influencing the behavior of low angular momentum general …

Fractal concepts have been introduced in the accretion disc as a new feature. Due to the
fractal nature of the flow, its continuity condition undergoes modifications. The conserved …

For low angular momentum axially symmetric accretion flow maintained in hydrostatic
equilibrium along the vertical direction, the value of the Mach number at the critical points …

A first-order correction in the α-viscosity parameter of Shakura & Sunyaev has been
introduced in the standard inviscid and thin accretion disk. A linearized time-dependent …

In a novel approach to studying viscous accretion flows, viscosity has been introduced as a
perturbative effect, involving a first-order correction in the α-viscosity parameter. This method …
