General Relativistic Magnetohydrodynamic Bondi--Hoyle Accretion
General Relativistic Magnetohydrodynamic Bondi--Hoyle Accretion
2010/11/15
In this paper we present a fully relativistic study of axisymmetric magnetohydrodynamic Bondi{
Hoyle accretion onto a moving Kerr black hole. The equations of general relativistic magnetohydrodynamic...
Stability of general-relativistic accretion disks
Stability general-relativistic accretion disks
2010/11/15
Self-gravitating relativistic disks around black holes can form as transient structures in a number of astrophysical scenarios such as binary neutron star and black hole-neutron star coalescences, as ...
Accretion Discs with an Inner Spiral Density Wave
accretion accretion discs - binaries general - binaries close - stars dwarf novae - novae
2010/11/16
In Montgomery (2009a), we show that accretion discs in binary systems could retrogradely precess by the same physics that causes the Earth to retrogradely precess [i.e., tidal torques by the Moon and ...
Detection of Strong Millimeter Emission from the Circumstellar Dust Disk Around V1094 Sco: Cold and Massive Disk around a T Tauri Star in a Quiescent Accretion Phase?
stars circumstellar matter — stars individual formation
2010/11/9
We present the discovery of a cold massive dust disk around the T Tauri star V1094 Sco in the Lupus molecular cloud from the 1.1 millimeter continuum observations with AzTEC on ASTE. A compact (r .320...
Does an Average White Dwarf Have Enough Mass to Prevent an Accretion Disk Tilt?
astrophysics accretion white dwarfs cataclysmic variables
2010/11/16
In a recent publication, we introduce the lift force as a common source to accretion disk
tilt that is likely relevant to accretion disk systems. Lift is generated by slightly different supersonic ga...
The role of accretion disks in the formation of massive stars
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
We present radiation hydrodynamics simulations of the collapse of massive pre-stellar cores. We treat frequency dependent radiative feedback from stellar evolution and accretion luminosity at a numeri...
