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 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...
