The EBLM project – XIII. The absolute dynamical masses of the circumbinary planet host TOI-1338/BEBOP-1, and applications to the study of exoplanet atmospheres

Monthly Notices of the Royal Astronomical Society
ABSTRACT High-contrast eclipsing binaries with low mass M-dwarf secondaries are precise benchmark stars to build empirical mass–radius relationships for fully convective low-mass ($\rm M_{\star } \lt 0.35\, M_{\odot }$) dwarf stars. The contributed light of the M-dwarf in such binaries is usually much less than one per cent at optical ...

Characterisation of exoplanet atmospheres using high-resolution spectroscopy [PDF]

The characterisation of exoplanet atmospheres is crucial to understanding planet formation, the exploration of extreme atmospheric physics, finding habitable worlds, and searching for extraterrestrial life, but challenged by the overwhelming star-to ...

The composition and dynamics of exoplanet atmospheres. [PDF]

The study of exoplanets has rapidly developed in the last twenty years, and the detailed characterization of planetary atmospheres has become a key area of research.\ud \ud For transiting planets around bright stars, atmospheric features can be detected with transmission spectroscopy.

Observational constraints of exoplanet clouds

, 2023
We entered a new era in extrasolar planets characterisation. We are indeed given access to constraints on their meteorology. New facilities have been designed specifically for exoplanet atmospheric characterisation.

Coupled Orbital and Interior Evolution of Sub-Neptunes

The Astrophysical Journal
Recent observations have yielded the first measurements of young exoplanet demographics. Close-in sub-Neptune occurrence rates appear to rise from young (10–100 Myr) to intermediate (100 Myr–1 Gyr) ages and then decline sharply in the old (≳1 Gyr) Kepler

Exoplanet Aeronomy: A Case Study of WASP-69 b’s Variable Thermosphere

The Astronomical Journal
Aeronomy, the study of Earth’s upper atmosphere and its interaction with the local space environment, has long traced changes in the thermospheres of Earth and other solar system planets to solar variability in the X-ray and extreme-ultraviolet ...

Analytic Modeling of Tidally Locked Rocky Planet Atmospheres across Dynamical Regimes

The Astrophysical Journal
We present a new first-principles analytic approach to interpreting eclipses and phase curves of rocky planets. Observations with JWST have reported nondetections of atmospheres around the majority of hot rocky planets orbiting M dwarfs. However, most of
