'exoplanet': Gradient-based probabilistic inference for exoplanet data & other astronomical time series [PDF]

open access: yesJournal of Open Source Software, 2021
"exoplanet"is a toolkit for probabilistic modeling of astronomical time series data, with a focus on observations of exoplanets, using PyMC3 (Salvatier et al., 2016).

Early Release Science of the exoplanet WASP-39b with JWST NIRCam [PDF]

open access: yesNature, 2022
Time-series observations from the JWST of the transiting exoplanet WASP-39b show gaseous water in the planet’s atmosphere and place an upper limit on the abundance of methane.

Identification of carbon dioxide in an exoplanet atmosphere [PDF]

open access: yesNature, 2022
Carbon dioxide (CO_2) is a key chemical species that is found in a wide range of planetary atmospheres. In the context of exoplanets, CO_2 is an indicator of the metal enrichment (that is, elements heavier than helium, also called ‘metallicity’)^ 1 – 3 ,

Dark exoplanets

open access: yesPhysical Review D, 2023
The prevailing assumption is that all exoplanets are made of ordinary matter. However, we propose an unconventional possibility that some exoplanets could be made of dark matter, which we name "dark exoplanets." In this paper, we explore methods to search for dark exoplanets, including the mass-radius relation, spectroscopy, missing transit, and ...

Large Interferometer For Exoplanets (LIFE). I. Improved exoplanet detection yield estimates for a large mid-infrared space-interferometer mission [PDF]

open access: yesAstronomy & Astrophysics, 2021
One of the long-term goals of exoplanet science is the atmospheric characterization of dozens of small exoplanets in order to understand their diversity and search for habitable worlds and potential biosignatures.

Modeling of Magnetospheres of Terrestrial Exoplanets in the Habitable Zone around G-Type Stars

open access: yesUniverse, 2022
Using a paraboloid model of an Earth-like exoplanetary magnetospheric magnetic field, developed from a model of the Earth, we investigate the magnetospheric structure of planets located in the habitable zone around G-type stars.
