Periodic massloss from viscous accretion flows around black holes
Santabrata Das, Indranil Chattopadhyay, Anuj Nandi +1
We investigate the behaviour of low angular momentum viscous accretion flows around black holes using Smooth Particle Hydrodynamics (SPH) method. Earlier, it has been observed that…
Low angular momentum flow model for Sgr A*
Toru Okuda, Diego Molteni
We examine the low angular momentum flow model for Sgr A* using two-dimensional hydrodynamical calculations based on the parameters of the specific angular momentum and total energ…
How initial and boundary conditions affect protoplanetary migration in a turbulent sub-Keplerian accretion disc: 2D non viscous SPH simulations
Vincenzo Costa, Valerio Pirronello, Gaetano Belvedere +3
Current theories on planetary formation establish that giant planet formation should be contextual to their quick migration towards the central star due to the protoplanets-disc in…
The Jets and Disc of SS 433 at Super-Eddington Luminosities
Toru Okuda, Galina V. Lipunova, Diego Molteni
We examine the jets and the disc of SS 433 at super-Eddington luminosities with 600 times Eddington critical accretion rate by time-dependent two-dimensional radiation hydrodynamic…
Shock oscillation model for QPOs in stellar-mass and supermassive black holes
T. Okuda, V. Teresi, D. Molteni
We numerically examine centrifugally supported shock waves in 2D rotating accretion flows around a stellar-mass (10M_sun) and a supermassive (10^6M_sun) black holes over a wide ran…
Steady shocks around black holes produced by sub-keplerian flows with negative energy
D. Molteni, G. Gerardi, V. Teresi
We discuss a special case of formation of axisymmetric shocks in the accretion flow of ideal gas onto a Schwarzschild black hole: when the total energy of the flow is negative. The…
