Formation of Accretion Disks in Close-Binary Systems with Magnetic Fields
Accretion Disks Close-Binary Systems Magnetic Fields
2011/1/10
We have developed a three-dimensional numerical model and applied it to simulate plasma flows in semi-detached binary systems whose accretor possesses a strong intrinsic magnetic field. The model is b...
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 ...
Connections Between Tilted Accretion Disks Around White Dwarfs and Substellar Companions
Substellar companions infrared excess debris disks protoplanetary disks exo-zodiacal dust
2010/11/16
Accretion disks in white dwarf systems are believed to be tilted. In a recent publication, the lift force has been suggested to be a source to disk tilt, a source that is likely relevant to all accret...
Accretion Disks Around Binary Black Holes: A Quasistationary Model
ProAccretion Disks Binary Black Holes Quasistationary Model
2010/11/9
Tidal torques acting on a gaseous accretion disk around a binary black hole can create a gap in the disk near the orbital radius. At late times, when the binary inspiral timescale due to gravitational...
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...
Accretion Disks in Evolved Cataclysmic Variables
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/22
We explore conditions and structure of accretion disks in short-period Cata- clysmic Variables (CVs), which have evolved beyond the period minimum. We show that accretion discs in systems with extreme...
Resistivity-driven State Changes in Vertically Stratified Accretion Disks
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/22
We investigate the effect of shear viscosity and Ohmic resistivity on the magnetorotational instability (MRI) in vertically stratified accretion disks through a series of local simulations computed wi...
