, 2014 More than a thousand exoplanets have been discovered over the last decade. Perhaps more excitingly, probing their atmospheres has become possible. We now have spectra of hot Jupiters like HD 189733b and HD 209458b, of Neptune-like planets like GJ1214b and even smaller planets are within reach.

Formation of Near-surface Atmospheric Inversion and Surface Inversion in Hothouse Climates
The Astrophysical JournalA hothouse climate may develop throughout Earth’s history and its warming future, and on potentially habitable exoplanets near the inner edge of the habitable zone.

The Astrophysical JournalHot Jupiters are typically considered to be tidally locked due to their short orbital periods. The extreme irradiation can result in atmospheric species becoming thermally ionized on the dayside, which then interact with the planet’s magnetic field by ...

Evaporation of Close-in Sub-Neptunes by Cooling White Dwarfs
The Astrophysical Journal LettersMotivated by the recent surge in interest concerning white dwarf (WD) planets, this work presents the first numerical exploration of WD-driven atmospheric escape, whereby the high-energy radiation from a hot/young WD can trigger the outflow of the ...

Extreme Winds on the Emerging Dayside of an Ultrahot Jupiter
The Astrophysical Journal LettersHigh-resolution spectroscopy provides a unique opportunity to directly probe atmospheric dynamics by resolving Doppler shifts of planetary signals as a function of orbital phase. Using the optical spectrometer the Keck Planet Finder, we carry out a pilot

HD 206893 B at High Spectral Resolution with the Keck Planet Imager and Characterizer
The Astronomical JournalWe present an atmospheric characterization and orbital analysis of HD 206893 B, an exceptionally red, L/T-transition substellar companion in a multiplanetary system, via Keck Planet Imager and Characterizer (KPIC) high-resolution ( R ∼ 35,000) K- band ...

Atmospheric Collapse and Reinflation through Impacts for Terrestrial Planets around M Dwarfs
The Astrophysical Journal LettersDetection of an atmosphere around a terrestrial exoplanet will be a major milestone in the field, but our observational capacities are biased towards tidally locked, close-in planets orbiting M dwarf stars. The atmospheres of these planets are vulnerable

Asymmetries in the Simulated Ozone Distribution on TRAPPIST-1e due to Orography
The Astrophysical JournalTRAPPIST-1e is a tidally locked rocky exoplanet orbiting the habitable zone of an M dwarf star. Upcoming observations are expected to reveal new rocky exoplanets and their atmospheres around M dwarf stars.
