Seven rocky planets orbit the nearby dwarf star TRAPPIST-1, providing a unique opportunity
to search for atmospheres on small planets outside the Solar System. Thanks to the recent …

TRAPPIST-1 is a fantastic nearby (∼ 39.14 light years) planetary system made of at least
seven transiting terrestrial-size, terrestrial-mass planets all receiving a moderate amount of …

We have collected transit times for the TRAPPIST-1 system with the Spitzer Space
Telescope over four years. We add to these ground-based, HST, and K2 transit-time …

Context. Previous theoretical works on planet formation around low-mass stars have often
been limited to large planets and individual systems. As current surveys routinely detect …

The mass–luminosity relation for late-type stars has long been a critical tool for estimating
stellar masses. However, there is growing need for both a higher-precision relation and a …

Abstract The James Webb Space Telescope (JWST) will offer the first opportunity to
characterize terrestrial exoplanets with sufficient precision to identify high mean molecular …

We present a new method to detect planetary transits from time-series photometry, the transit
least squares (TLS) algorithm. TLS searches for transit-like features while taking the stellar …

Context. The TRAPPIST-1 system hosts seven Earth-sized, temperate exoplanets orbiting an
ultra-cool dwarf star. As such, it represents a remarkable setting to study the formation and …

M dwarfs are common host stars to exoplanets but often lack atmospheric abundance
measurements. Late-M dwarfs are also good analogs to the youngest substellar …

Context. In the age of JWST, temperate terrestrial exoplanets transiting nearby late-type M
dwarfs provide unique opportunities for characterising their atmospheres, as well as …
