Two-dimensional Eclipse Mapping of the Hot-Jupiter WASP-43b with JWST MIRI/LRS

The Astronomical Journal
We present eclipse maps of the two-dimensional thermal emission from the dayside of the hot-Jupiter WASP-43b, derived from an observation of a phase curve with the JWST MIRI/LRS instrument.

Asymmetries in the Simulated Ozone Distribution on TRAPPIST-1e due to Orography

The Astrophysical Journal
TRAPPIST-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.

The Response of Planetary Atmospheres to the Impact of Icy Comets. I. Tidally Locked Exo-Earths

The Astrophysical Journal
Impacts by rocky and icy bodies are thought to have played a key role in shaping the composition of solar system objects, including the Earth’s habitability. Hence, it is likely that they play a similar role in exoplanetary systems. We investigate how an

A Time-resolved High-resolution Spectroscopic Analysis of Ionized Calcium and Dynamical Processes in the Ultra-hot Jupiter HAT-P-70 b

The Astrophysical Journal Letters
We present the first transmission spectroscopy study of an exoplanet atmosphere with the high-resolution mode of the new Gemini High-resolution Optical SpecTrograph (GHOST) instrument at the Gemini South Observatory. We observed one transit of HAT-P-70 b—

Haze Optical Depth in Exoplanet Atmospheres Varies with Rotation Rate: Implications for Observations

The Astronomical Journal
Transmission spectroscopy supports the presence of uncharacterized, light-scattering and -absorbing hazes in the atmospheres of many exoplanets. The complexity of factors influencing the formation, 3D transport, radiative impact, and removal of hazes ...

Comparative Planetology of Magnetic Effects in Ultrahot Jupiters: Trends in High-resolution Spectroscopy

The Astrophysical Journal
Ultrahot Jupiters (UHJs), being the hottest class of exoplanets known, provide a unique laboratory for testing atmospheric interactions with internal planetary magnetic fields at a large range of temperatures. Thermal ionization of atmospheric species on

Limited Hysteresis in the Atmospheric Dynamics of Hot Jupiters

The Astrophysical Journal
Over the past two decades, a coherent picture has emerged of the atmospheric dynamics of hot Jupiters from a combination of three-dimensional general circulation models and astronomical observations.

Spectroscopically Resolved Partial Phase Curve of the Rapid Heating and Cooling of the Highly Eccentric Hot Jupiter HAT-P-2b with WFC3

The Astronomical Journal
The extreme environments of transiting close-in exoplanets in highly eccentric orbits are ideal for testing exoclimate physics. Spectroscopically resolved phase curves not only allow for the characterization of their thermal response to irradiation ...

Is the Atmosphere of the Ultra-hot Jupiter WASP-121 b Variable?

The Astrophysical Journal Supplement Series
We present a comprehensive analysis of the Hubble Space Telescope observations of the atmosphere of WASP-121 b, an ultra-hot Jupiter. After reducing the transit, eclipse, and phase-curve observations with a uniform methodology and addressing the biases ...
