The First Galaxies: Assembly of Disks and Prospects for Direct Detection
cosmology observations galaxies formation galaxies
2010/11/9
The James Webb Space Telescope (JWST) will enable observations of galaxies at redshifts z & 10 and hence allow to test our current understanding of structure formation at very early times. Previous wo...
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...
Asymmetric Line Profiles in Spectra of Gaseous Metal Disks Around Single White Dwarfs
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
Around several single DAZ and DBZ white dwarfs metal-rich disks have been observed, which are mostly believed to originate from disruption of smaller rocky planetesimals. In some cases the material do...
A Spitzer IRS Study of Debris Disks Around Planet-Host Stars

Since giant planets scatter planetesimals within a few tidal radii of their orbits, the locations of existing planetesimal belts indicate regions where giant planet formation failed in bygone protoste...
We present a novel theoretical tool to analyze the dynamical behaviour of a Be disk fed by non-constant decretion rates. It is mainly based on the computer code HDUST, a fully three-dimensional radiat...
