The Astronomical Journal, 2023 We present high-resolution dayside thermal emission observations of the exoplanet WASP-18 b using IGRINS on Gemini South. We remove stellar and telluric signatures using standard algorithms, and we extract the planet signal via cross-correlation with ...

Photochemistry in Hot H2-dominated Exoplanet Atmospheres [PDF]
Astrophysical Journal, 2019 Photochemistry has the potential to substantially impact the atmospheric composition of exoplanets with consequences on the radiative transfer, thermal structure, and dynamics of the atmospheres, particularly in UV-rich stellar environments.

Hydrogen sulfide and metal-enriched atmosphere for a Jupiter-mass exoplanet. [PDF]
NatureAs the closest transiting hot Jupiter to Earth, HD 189733b has been the benchmark planet for atmospheric characterization 1,2,3. It has also been the anchor point for much of our theoretical understanding of exoplanet atmospheres from composition 4 ...

Highlights in the Study of Exoplanet Atmospheres [PDF]
Nature, 513, pp. 345-352, 2014, 2014 Exoplanets are now being discovered in profusion. However, to understand their character requires spectral models and data. These elements of remote sensing can yield temperatures, compositions, and even weather patterns, but only if significant improvements in both the parameter retrieval process and measurements are achieved.

The EXoplanet Climate Infrared TElescope - EXCITE
, 2021 EXCITE is a balloon-borne near-infrared spectrometer designed to observe from 0.6 to 4 micron and to perform phase-resolved spectroscopy of hot Jupiters during a Long-Duration Balloon (LDB) flight from Antarctica in 2024. These spectral ...

Clouds in Exoplanetary Atmospheres [PDF]
, 2020 Today, we know ~4330 exoplanets orbiting their host stars in ~3200 planetary systems. The diversity of these exoplanets is large, and none of the known exoplanets is a twin to any of the solar system planets, nor is any of the known extrasolar planetary systems a twin of the solar system.

IGRINS Observations of WASP-127 b: H2O, CO, and Super-solar Atmospheric Metallicity in the Inflated Sub-Saturn [PDF]
Astronomical JournalHigh-resolution spectroscopy of exoplanet atmospheres provides insights into their composition and dynamics from the resolved line shape and depth of thousands of spectral lines. WASP-127 b is an extremely inflated sub-Saturn (R p = 1.311 R Jup, M p

Exoplanet winds: Modelling atmospheric dynamics via resolved spectral lines
, 2021 This thesis benchmarked a new probe of atmospheric dynamics in exoplanet atmospheres by resolving the spectral lines stemming from these far atmospheres and then modelling their line shape taking into account the broadening from atmospheric winds. This gives us a window into atmospheric winds for these far away worlds only limited by the depths of the ...
