Laboratory modeling of MHD accretion disks [PDF]
Comptes Rendus. PhysiqueThis review article summarizes two decades of laboratory research aimed at understanding the dynamics of accretion disks, with particular emphasis on magnetohydrodynamic experiments involving liquid metals and plasmas.

Foundations of Black Hole Accretion Disk Theory
Living Reviews in Relativity, 2013 This review covers the main aspects of black hole accretion disk theory. We begin with the view that one of the main goals of the theory is to better understand the nature of black holes themselves.

Discovery of Two Different Full Disk Evolutionary Patterns of M-type T Tauri Stars with LAMOST DR8
The Astrophysical Journal, 2023 The full disk, full of gas and dust, determines the upper limit of planet masses, and its lifetime is critical for planet formation, especially for giant planets.

Outflows and particle acceleration in the accretion disks of young stars [PDF]
EPJ Web of Conferences, 2019 Magneto-gas-dynamic (MGD) outflows from the accretion disks of T Tauri stars with fossil large-scale magnetic fileld are investigated. We consider two mechanisms of the outflows: rise of the magnetic flux tubes (MFT) formed in the regions of efficient ...

ACCRETION DISKS WITH A LARGE SCALE MAGNETIC FIELD AROUND BLACK HOLES
Acta Polytechnica, 2013 We consider accretion disks around black holes at high luminosity, and the problem of the formation of a large-scale magnetic field in such disks, taking into account the non-uniform vertical structure of the disk.

The Astrophysical Journal, 2023 We present global 3D radiation magnetohydrodynamic simulations of accretion onto a 6.62 solar-mass black hole, with quasi-steady-state accretion rates reaching 0.016–0.9 times the critical accretion rate, which is defined as the accretion rate for ...

Global simulations of accretion flows onto perturbers embedded in magnetized disks
Astronomy & AstrophysicsWe present the highest resolution global magnetohydrodynamic simulations to date of gas flow around a low-mass perturber with a mass ratio q ∈ [10−4, 10−3], embedded in an accretion disk around a massive central object.

On the Formation and Interaction of Multiple Supermassive Stars in Cosmological Flows
The Astrophysical Journal, 2023 Supermassive primordial stars with masses exceeding ∼10 ^5 M _⊙ that form in atomically cooled halos are the leading candidates for the origin of high-redshift quasars at z > 6.

ACCRETION INTO BLACK HOLES WITH MAGNETIC FIELDS, AND RELATIVISTIC JETS
Odessa Astronomical Publications, 2011 We discuss the problem of the formation of a large-scale magnetic field in the accretion disks around black holes, taking into account the non-uniform vertical structure of the disk.

LAMOST Reveals Long-lived Protoplanetary Disks
The Astronomical JournalWhile both observations and theories demonstrate that protoplanetary disks are not expected to live much longer than ∼10 Myr, several examples of prolonged disks have been observed in the past.
