Exploration of Exoplanet Atmospheres with the James Webb Space Telescope
Sasha Hinkley, David K. Sing
The James Webb Space Telescope (JWST) is providing transformative characterization capabilities for the study of both transiting and directly imaged extrasolar planets. Observation…
Flow-Driven Limb-Asymmetry of Haze Distribution Part I: An Analytical Framework for Predicting the Size Distribution of Photochemical Hazes Across the Two Limbs of hot-Jupiters
Mei Ting Mak, Thaddeus D. Komacek, Nathan J. Mayne +1
The paper presents an analytical model that predicts how photochemical haze particle sizes are distributed between the morning and evening limbs of hot‑Jupiter exoplanets, accounti…
Aerosols and hydrocarbons in the atmosphere of a white dwarf planet
Ryan J. MacDonald, Christopher E. O'Connor, Victoria A. Boehm +15
Most stars, including our Sun, will one day evolve into red giants and, subsequently, white dwarfs. Several planet candidates have recently been identified orbiting white dwarfs, d…
Characterizing Transiting Exoplanet Atmospheres in the 2030s with the Hubble Space Telescope
Joshua D. Lothringer, Hannah R. Wakeford, Robert C. Frazier +7
The Hubble Space Telescope inaugurated the era of exoplanet atmospheric characterization. While the James Webb Space Telescope has largely taken up the mantle of infrared atmospher…
Magnesium Silicate Clouds in the Atmosphere of HD 209458b from a Rule-Based Tree-Structured Data Reduction
Katy L. Chubb, David Grant, Hannah R. Wakeford +14
HD 209458b is the canonical hot Jupiter: the first to have its atmosphere measured and the first to hint at the role of aerosols in exoplanet atmospheres through the muting of Na a…
A High-Resolution NUV Transmission Spectrum of KELT-9b: Mg II and Fe II Escaping from the Hottest Known Giant Planet
Austin Baldwin, Joshua D. Lothringer, Leonardo A. Dos Santos +5
We present high-resolution NUV observations from Hubble Space Telescope's (HST) Space Telescope Imaging Spectrograph (STIS) data for the hottest known gas planet, KELT-9b. Observat…
