Multifaceted Accretion: The Interplay of Turbulence, Resistivity, Thermal Transport, and Dust around Black Holes
Asish Jyoti Boruah, Liza Devi, Biplob Sarkar
Accretion near black holes (BHs) is multidimensional, with turbulence, resistivity, thermal transport, and dust dynamics all playing essential roles. In cold accretion discs (ADs)…
An Overview of the Effect of Self-Gravity on the Structure of Accretion Discs
Darashan Saikia, Liza Devi, Biplob Sarkar +1
In astrophysical systems like X-ray binaries (XRBs), active galactic nuclei (AGN), and young stellar objects (YSOs), we often observe a very fundamental structure called accretion…
An Overview of Rossby Wave Instability in Accretion Discs surrounding Black Holes
Bibhuti Bhusan Dutta, Liza Devi, Biplob Sarkar +1
The Rossby Wave Instability (RWI) has become an important concept in understanding the hydrodynamics (HDs) of accretion discs (ADs), especially in systems around black holes (BHs)…
Relativistic Accretors and High Energy X-Ray view
Asish Jyoti Boruah, Liza Devi, Biplob Sarkar
Relativistic accretors are cosmic objects that pull matter from their surroundings at speeds almost equal to the light's speed. Because of the tremendous gravitational force from t…
An Overview of Numerical Simulations in Accretion Physics
Biplob Sarkar, Liza Devi, Asish Jyoti Boruah
Accretion physics studies the process of gravitational capture of ambient matter by massive stars. The background processes are very challenging to observe and measure due to the e…
Accretion Disc Outbursts and Stability Analysis
Liza Devi, Asish Jyoti Boruah, Biplob Sarkar
Accretion disc outbursts are re-occurring events observed in various astrophysical systems, including X-ray binaries and cataclysmic variables. These outbursts are characterized by…
