High Mass Inner Regions Found in Five Outbursting Sources
Jenny K. Calahan, Edwin A. Bergin, Merel van't Hoff +3
Young stellar objects are thought to commonly undergo sudden accretion events that result in a rise in bolometric luminosity. These outbursts likely coincide with the onset of plan…
Chemistry in Protoplanetary Disks
Ke Zhang
Planets are formed inside disks around young stars. The gas, dust, and ice in these natal disks are the building materials of planets, and therefore their compositions fundamentall…
The Carbon Isotopic Ratio and Planet Formation
Edwin A. Bergin, Arthur Bosman, Richard Teague +6
We present the first detection of 13CCH in a protoplanetary disk (TW Hya). Using observations of C2H we measure CCH/13CCH = 65 +/- 20 in gas with a CO isotopic ratio of 12CO/13CO =…
Molecular Gas Tracers in Young and Old Protoplanetary Disks
Dana E. Anderson, L. Ilsedore Cleeves, Geoffrey A. Blake +6
Molecular emission is used to investigate both the physical and chemical properties of protoplanetary disks. Therefore, to accurately derive disk properties, we need a thorough und…
How large is a disk -- what do protoplanetary disk gas sizes really mean?
Leon Trapman, Giovanni Rosotti, Ke Zhang +1
It remains unclear what mechanism is driving the evolution of protoplanetary disks. Direct detection of the main candidates, either turbulence driven by magnetorotational instabili…
A gap-sharing planet pair shaping the crescent in HD 163296: a disk sculpted by a resonant chain
Juan Garrido-Deutelmoser, Cristobal Petrovich, Carolina Charalambous +2
ALMA observations of the disk around HD 163296 have resolved a crescent-shape substructure at around 55 au, inside and off-center from a gap in the dust that extends from 38 au to…
