A gaseous metal disk around a white dwarf.
TL;DR: A metal-rich gas disk around a moderately hot and young white dwarf implies that planetary systems may form around high-mass stars.
Journal ArticleDOI
Disk Winds and Disk Emission Lines
Norman Murray,J. Chiang +1 more
TL;DR: In this article, it was shown that a thin disk illuminated by a central source will produce single peaked broad emission lines if there is a wind emerging from the disk, and the lines are single peaked, in spite of the fact that the emission comes from gas on essentially circular orbits.
Journal ArticleDOI
H2o and oh gas in the terrestrial planet-forming zones of protoplanetary disks
Colette Salyk,Klaus M. Pontoppidan,Geoffrey A. Blake,Fred Lahuis,Ewine F. van Dishoeck,Neal J. Evans +5 more
TL;DR: In this article, the authors present detections of numerous 10-20 μm H 2O emission lines from two protoplanetary disks around the T Tauri stars AS 205A and DR Tau, obtained using the InfraRed Spectrograph on the Spitzer Space Telescope.

Weak Turbulence in the HD 163296 Protoplanetary Disk Revealed by ALMA CO Observations
Kevin Flaherty,A. Meredith Hughes,Katherine A. Rosenfeld,Sean M. Andrews,Eugene Chiang,Jacob B. Simon,Jacob B. Simon,Skylar Kerzner,David J. Wilner +8 more
TL;DR: In this paper, the authors derived stringent limits on the non-thermal motions in the upper layers of the outer disk such that any contribution to the line-widths from turbulence is 30AU) disk.

Dynamical Evidence for a Black Hole in the Microquasar XTE J1550–564*
Jerome A. Orosz,Paul J. Groot,Michiel van der Klis,Jeffrey E. McClintock,Michael R. Garcia,Ping Zhao,Raj K. Jain,Charles D. Bailyn,Ronald A. Remillard +8 more
TL;DR: In this article, the mass of the companion star in the microquasar system XTE J1550-564 was derived from the ellipsoidal light and radial velocity curves.
