Systematic Variations of CO Gas Abundance with Radius in Gas-rich Protoplanetary Disks
Ke Zhang, Edwin A. Bergin, Kamber R. Schwarz +2
CO is the most widely used gas tracer of protoplanetary disks. Its abundance is usually assumed to be an interstellar ratio throughout the warm molecular layer of the disk. But rec…
Unlocking CO Depletion in Protoplanetary Disks II. Primordial C/H Predictions Inside the CO Snowline
Kamber R. Schwarz, Edwin A. Bergin, L. Ilsedore Cleeves +4
CO is thought to be the main reservoir of volatile carbon in protoplanetary disks, and thus the primary initial source of carbon in the atmospheres of forming giant planets. Howeve…
Line Ratios Reveal N2H+ Emission Originates Above the Midplane in TW Hydrae
Kamber R. Schwarz, Richard Teague, Edwin A. Bergin
Line ratios for different transitions of the same molecule have long been used as a probe of gas temperature. Here we use ALMA observations of the N2H+ J~=~1-0 and J~=~4-3 lines in…
Realizing the Unique Potential of ALMA to Probe the Gas Reservoir of Planet Formation
L. Ilsedore Cleeves, Ryan Loomis, Richard Teague +21
Understanding the origin of the astonishing diversity of exoplanets is a key question for the coming decades. ALMA has revolutionized our view of the dust emission from protoplanet…
