DIRECT MEASURE OF RADIATIVE AND DYNAMICAL PROPERTIES OF AN EXOPLANET ATMOSPHERE [PDF]
The Astrophysical Journal Letters, 2016 ABSTRACT Two decades after the discovery of 51 Peg b, the formation processes and atmospheres of short-period gas giants remain poorly understood. Observations of eccentric systems provide key insights on those topics as they can illuminate how a planet’s atmosphere responds to changes in incident flux.

TOI-1670 c, a 40 day Orbital Period Warm Jupiter in a Compact System, Is Well Aligned
The Astrophysical Journal Letters, 2023 We report the measurement of the sky-projected obliquity angle λ of the warm Jovian exoplanet TOI-1670 c via the Rossiter–McLaughlin effect. We observed the transit window during UT 2023 April 20 for 7 continuous hours with NEID on the 3.5 m WIYN ...

Atmospheric dynamics of a near tidally locked Earth-sized planet [PDF]
Nature Astronomy, 2022 The discovery and characterization of Earth-sized planets that are in, or near, a tidally locked state are of crucial importance to understanding terrestrial planet evolution. For this purpose Venus is a clear analogue.

Angewandte Chemie, EarlyView.Under extreme pressure and temperature, superionic water acts as a strong superacid, catalyzing methane polycondensation through pentacoordinated carbonium ions (CH5+). This discovery reveals the non‐classical carbocation chemistry underlying the early stages of diamond formation in water under extreme conditions.

A New Method for Studying Exoplanet Atmospheres Using Planetary Infrared Excess [PDF]
Astrophysical Journal, 2020 To date, the ability for observers to reveal the composition or thermal structure of an exoplanet’s atmosphere has rested on two techniques: high-contrast direct imaging and time-series observations of transiting exoplanets.

Validating AU Microscopii d with Transit Timing Variations
The Astronomical Journal, 2023 AU Mic is a young (22 Myr), nearby exoplanetary system that exhibits excess transit timing variations (TTVs) that cannot be accounted for by the two known transiting planets nor stellar activity.
