Evidence for Multiple Pathways to Deuterium Enhancements in Protoplanetary Disks
Evidence Multiple Pathways Deuterium Enhancements Protoplanetary Disks
2012/2/23
The distributions of deuterated molecules in protoplanetary disks are expected to depend on the molecular formation pathways. We use observations of spatially resolved DCN emission from the disk aroun...
AMBER high-spectral resolution interferometry of Be stars: More than just stars and disks?
high-spectral resolution interferometry stars disks
2011/10/17
High spectral-resolution Br-gamma VLTI/AMBER observations of classical Be stars reveal complex visibility, phase, and closure phase profiles, which were not seen in previous lower-resolution data. The...

Star formation self-gravitating disks active galactic Metallicity gradients
2011/10/11
It has been suggested that the high metallicity generally observed in active galactic nuclei (AGNs) and quasars originates from ongoing star formation in the self-gravitating part of accretion disks a...

2011/10/11
We study the role resonant scattering plays in the transport of Lyman-alpha photons in accreting protoplanetary disk systems subject to varying degrees of dust settling. While the intrinsic stellar FU...
Fragment Production and Survival in Irradiated Disks: A Comprehensive Cooling Criterion
Fragment Production Survival Irradiated Disks Comprehensive Criterion
2011/9/27
Accretion disks that become gravitationally unstable can fragment into stellar or sub-stellar companions. The formation and survival of these fragments depends on the precarious balance between self-g...
