CO Ro-vibrational Spectroscopy of AB Aurigae -- A Potential Point Source is Present
Janus Kozdon, Jeffrey Fung, Sean D. Brittain +4
The Herbig Ae star AB Aurigae hosts a vast, low-inclination protoplanetary disk that exhibits a plethora of substructures, including the protoplanet candidate AB Aur b. We present…
Dynamical Excitation as a probe of planetary origins
Brad M. S. Hansen, Tze-Yeung Yu, Neel Nagarajan +1
We present a set of numerical simulations of the dynamical evolution of compact planetary systems migrating in a protoplanetary disk whose inner edge is sculpted by the interaction…
Water vapor as a probe of the origin of gas in debris disks
Yasuhiro Hasegawa, Riouhei Nakatani, Isabel Rebollido +5
Debris disks embrace the formation and evolution histories of planetary systems. Recent detections of gas in these disks have received considerable attention, as its origin ties up…
Planet Mass and Metallicity: The Exoplanets and Solar System Connection
Mark R. Swain, Yasuhiro Hasegawa, Daniel P. Thorngren +1
Theoretical studies of giant planet formation suggest that substantial quantities of metals - elements heavier than hydrogen and helium - can be delivered by solid accretion during…
Bulk and atmospheric metallicities as direct probes of sequentially varying accretion mechanisms of gas and solids onto planets
Yasuhiro Hasegawa, Mark R. Swain
Core accretion is the standard scenario of planet formation, wherein planets are formed by sequential accretion of gas and solids, and is widely used to interpret exoplanet observa…
