Context. We present angle-dependent, broad-band intensity spectra from accretion disks around black holes of 10 M⊙. In our computations disks are assumed to be slim, which means that the radial advect...

Thermal conduction between a cool accretion disk and a hot inner corona can result in either evaporation of the disk or condensation of the hot corona. At low mass accretion rates, evaporation dominat...

Many different system types retrogradely precess, and retrograde precession could be from a tidal torque by the secondary on a misaligned accretion disk. However, a source to cause and maintain disk t...
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?

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...

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...
Dissecting the Moth: Discovery of an off-centered ring in the HD 61005 debris disk with high-resolution imaging

font style='font-size:12px;'>
2010/11/15
The debris disk known as “The Moth” is named after its unusually asymmetric surface brightness distribution. It is located around the ∼90Myr old G8V star HD 61005 at 34.5 pc and has previously b...
Spatially Resolved Star Formation History Along the Disk of M82 Using Multi-Band Photometric Data

We present the results on the star formation history and extinction in the disk of M82 over
spatial scales of 10′′ (180 pc). Multi-band photometric data covering from the far ultraviolet to the near...
