A Primordial Origin for the Gas-Rich Debris Disks Around Intermediate-Mass Stars
Riouhei Nakatani, Neal J. Turner, Yasuhiro Hasegawa +4
While most debris disks consist of dust with little or no gas, a fraction has significant amounts of gas detected via emission lines of CO, ionized carbon, and/or atomic oxygen. Al…
MAPS: Constraining Serendipitous Time Variability in Protoplanetary Disk Molecular Ion Emission
Abygail R. Waggoner, L. Ilsedore Cleeves, Ryan A. Loomis +12
Theoretical models and observations suggest that the abundances of molecular ions in protoplanetary disks should be highly sensitive to the variable ionization conditions set by th…
Primordial or Secondary? Testing models of debris disk gas with ALMA
Gianni Cataldi, Yuri Aikawa, Kazunari Iwasaki +13
The origin and evolution of gas in debris disks is still not well understood. Secondary gas production from cometary material or a primordial origin have been proposed. So far, obs…
Molecules with ALMA at Planet-forming Scales (MAPS). Complex Kinematics in the AS 209 Disk Induced by a Forming Planet and Disk Winds
Maria Galloway-Sprietsma, Jaehan Bae, Richard Teague +19
We study the kinematics of the AS 209 disk using the J=2-1 transitions of CO, CO, and CO. We derive the radial, azimuthal, and vertical velocity of the gas, ta…
