Gaps in Protoplanetary Disks as Signatures of Planets: I. Methodology and Validation
planet disk interactions protoplanetary disks planets and satellites detection radiative
2012/2/23
We examine the observational consequences of partial gaps being opened by planets in protoplanetary disks. We model the disk using a static alpha-disk model with detailed radiative transfer, parametri...
Turbulent Linewidths in Protoplanetary Disks: Predictions from Numerical Simulations
Turbulent Linewidths Protoplanetary Disks: Predictions Numerical Simulations
2011/10/11
Sub-mm observations of protoplanetary disks now approach the acuity needed to measure the turbulent broadening of molecular lines. These measurements constrain disk angular momentum transport, and fur...
The Role of Tiny Grains on the Accretion Process in Protoplanetary Disks
Tiny Grains Accretion Process Protoplanetary Disks
2011/10/9
Tiny grains such as PAHs have been thought to dramatically reduce the coupling between gas and magnetic fields in weakly ionized gas such as in protoplanetary disks (PPDs) because they provide tremend...

2011/10/9
The gas dynamics in protoplanetary disks (PPDs) is strongly affected by non-ideal MHD effects. Using a complex chemical reaction network with standard prescriptions for X-ray and cosmic-ray ionization...
