Context. Transmission spectroscopy is one of the most powerful techniques used to
characterize transiting exoplanets, since it allows for the abundance of the atomic and …

Ultracool dwarf stars are abundant, long-lived and uniquely suited to enable the
atmospheric study of transiting terrestrial companions with the JWST. Among them, the most …

The hot Neptune desert is one of the most sparsely populated regions of the exoplanet
parameter space, and atmosphere observations of its few residents can provide insights into …

Recent discoveries of Earth-sized planets transiting nearby M dwarfs have made it possible
to characterize the atmospheres of terrestrial planets via follow-up spectroscopic …

Flares, sometimes accompanied by coronal mass ejections (CMEs), are the result of sudden
changes in the magnetic field of stars with high energy release through magnetic …

LHS 1140 b is the second-closest temperate transiting planet to Earth with an equilibrium
temperature low enough to support surface liquid water. At 1.730±0.025 R⊕, LHS 1140 b …

Exoplanets in their infancy are ideal targets to probe the formation and evolution history of
planetary systems, including the planet migration and atmospheric evolution and …

Flares from magnetically active dwarf stars should produce relativistic particles capable of
creating γ-rays. So far, the only isolated main-sequence star besides the Sun to have been …

The high-energy radiative output, from the X-ray to the ultraviolet, of exoplanet host stars
drives photochemical reactions and mass loss in the upper regions of planetary …

The TEMPO (Transiting Exosatellites, Moons, and Planets in Orion) Survey is a proposed 30-
day observational campaign using the Nancy Grace Roman Space Telescope. By providing …
