Super-Earths span a wide range of bulk densities, indicating a diversity in interior conditions
beyond that seen in the solar system. In particular, an emerging population of low-density …

We report the discovery, mass, and radius determination of TOI-1801 b, a temperate mini-
Neptune around a young M dwarf. TOI-1801 b was observed in TESS sectors 22 and 49 …

Lyman α transits have been detected from several nearby exoplanets and are one of our
best insights into the atmospheric escape process. However, due to ISM absorption, we …

Context. One of the goals of the Echelle Spectrograph for Rocky Exoplanets and Stable
Spectroscopic Observations (ESPRESSO) Guaranteed Time Observations (GTO) …

We report on the precise radial velocity follow-up of TOI-544 (HD 290498), a bright K star
(V= 10.8), which hosts a small transiting planet recently discovered by the Transiting …

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 …

We present spright, a python package that implements a fast and lightweight mass–density–
radius relation for small planets. The relation represents the joint planetary radius and bulk …

Is the population of close-in planets orbiting M dwarfs sculpted by thermally driven escape or
is it a direct outcome of the planet formation process? A number of recent empirical results …

In Lammer et al.(2024), we defined Earth-like habitats (EHs) as rocky exoplanets within the
habitable zone of complex life (HZCL) on which Earth-like N2-O2-dominated atmospheres …

Long-term magma ocean phases on rocky exoplanets orbiting closer to their star than the
runaway greenhouse threshold—the inner edge of the classical habitable zone—may offer …
