The Interior and Atmosphere of the Habitable-zone Exoplanet K2-18b [PDF]

Astrophysical Journal, 2020
Exoplanets orbiting M-dwarfs present a valuable opportunity for their detection and atmospheric characterization. This is evident from recent inferences of H2O in such atmospheres, including that of the habitable-zone exoplanet K2-18b.

Direct Evidence of Photochemistry in an Exoplanet Atmosphere

, 2022
Photochemistry is a fundamental process of planetary atmospheres that is integral to habitability, atmospheric composition and stability, and aerosol formation. However, no unambiguous photochemical products have been detected in exoplanet atmospheres to

The single beacon: progresses in understanding Earth as an exoplanet using DSCOVR/EPIC observations

Frontiers in Remote Sensing
Almost 6000 exoplanets have thus far been confirmed, revolutionizing our understanding of planetary habitability. Yet, despite the identification of Earth-like exoplanets, definitive evidence of extraterrestrial life remains elusive.

Classification of Trajectories in a Two-planet Exosystem Using the Generalized Three-body Problem

The Astrophysical Journal, 2023
We deploy the theory of the generalized three-body problem to describe an exosystem composed of a host star, a transiting Jupiter-sized exoplanet, and an Earth-sized exoplanet.

Predictions of the Nancy Grace Roman Space Telescope Galactic Exoplanet Survey. II. Free-floating Planet Detection Rates [PDF]

Astronomical Journal, 2020
The Nancy Grace Roman Space Telescope (Roman) will perform a Galactic Exoplanet Survey (RGES) to discover bound exoplanets with semimajor axes greater than 1 au using gravitational microlensing. Roman will even be sensitive to planetary-mass objects that

The 0.5MJ transiting exoplanet WASP-13b [PDF]

, 2009
We report the discovery of WASP-13b, a low-mass $ M_{\rm p} = 0.46 ^_~M_J$ transiting exoplanet with an orbital period of 4.35298 $\pm$ 0.00004 days. The transit has a depth of 9 mmag, and although our follow-up photometry does not allow us to constrain ...
