Hydrogen airglow from an escaping ultrahot Jupiter atmosphere

Yapeng Zhang, Chenliang Huang, Aaron Householder +17

Intense high-energy irradiation of close-in gaseous exoplanets drives the rapid escape of their atmospheres, fundamentally shaping planetary demographics. While atmospheric loss is…

Unraveling the Mystery of the Peculiar and Young Hot Jupiter CoRoT-2b. I. HO and CO Detection from Dayside Observations with Gemini-S/IGRINS

Ying Shu, Lisa Dang, Antoine Darveau-Bernier +12

We present ground-based high-resolution spectroscopic pre-eclipse observations of the hot Jupiter CoRoT-2b obtained with the IGRINS spectrograph on Gemini South. Using cross-correl…

The compositions of the HR 8799 planets reflect accretion of both solids and metal-enriched gas

Jerry W. Xuan, Jean-Baptiste Ruffio, Yayaati Chachan +24

With four giant planets (, $T_\rm{eff}\sim900-1200$ K) orbiting between 15-70 au, HR 8799 provides an unparalleled testbed for studying giant planet formatio…

Limits on the Post-eclipse Emission Spectrum of HD 80606 b From High-Resolution Spectroscop

Luke Finnerty, Aurora Kesseli, Kyle Pearson +2

We present Keck/NIRSPEC -band observations of HD 80606 b, one of the most eccentric known exoplanets. HD 80606 b was observed after secondary eclipse, close to periastron, when…

Extreme winds on the emerging dayside of an ultrahot Jupiter

Yapeng Zhang, Joost P. Wardenier, Aaron Householder +16

High-resolution spectroscopy provides a unique opportunity to directly probe atmospheric dynamics by resolving Doppler shifts of planetary signal as a function of orbital phases. U…

Jupiter-like uniform metal enrichment in a system of multiple giant exoplanets

Jean-Baptiste Ruffio, Jerry W. Xuan, Yayaati Chachan +15

The accretion of icy and rocky solids during the formation of a gas giant planet is poorly constrained and challenging to model. Refractory species, like sulfur, are only present i…
