Oxygen Isotope Constraints on the Importance of Photochemical Processing in Protoplanetary Disks
Fred J. Ciesla, Eric Van Clepper, Jennifer Bergner +1
Observations have revealed evidence of photochemical processing in protoplanetary disks. This processing occurs in the photon dominated layer, the optically thin regions of the dis…
Dust Recycling and Icy Volatile Enhancement (DRIVE): A Novel Method of Volatile Enrichment in Cold Giant Planets
Eric R. Van Clepper, Felipe Alarcón, Edwin Bergin +1
Giant planet atmospheres are thought to reflect the gas phase composition of the disk when and where they formed. However, these atmospheres may also be polluted via solid accretio…
Direct Measurement of Extinction in a Planet-Hosting Gap
G. Cugno, S. Facchini, F. Alarcon +12
Recent disk observations have revealed multiple indirect signatures of forming gas giant planets, but high-contrast imaging has rarely confirmed the presence of the suspected pertu…
Burned to ashes: How the thermal decomposition of refractory organics in the inner protoplanetary disc impacts the gas-phase C/O ratio
Adrien Houge, Anders Johansen, Edwin Bergin +5
The largest reservoir of carbon in protoplanetary discs is stored in refractory organics, which thermally decompose into the gas-phase at the organics line, well interior to the wa…
