Context. 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 …

A benchmark brown dwarf (BD) is a BD whose properties (eg, mass and chemical
composition) are precisely and independently measured. Benchmark BDs are valuable in …

We compare high angular resolution mid-infrared (mid-IR) and Atacama Large Millimeter/
submillimeter Array (ALMA) far-infrared (far-IR) images of twelve nearby (median 21 Mpc) …

Isotope ratios have recently been measured in the atmospheres of directly imaged and
transiting exoplanets from ground-based observations. The arrival of JWST allows us to …

Abstract epsilon Eridani is a young planetary system hosting a complex multibelt debris disk
and a confirmed Jupiter-like planet orbiting at 3.48 au from its host star. Its age and …

Context. Young brown dwarfs exhibit atmospheric characteristics similar to those of super-
Jupiters, providing a unique opportunity to study planetary atmospheres. Atmospheric …

Context. The diffusion of adaptive optics systems in astronomical instrumentation for large
ground-based telescopes is rapidly increasing and the pyramid wavefront sensor is …

Proxima b is a rocky exoplanet in the habitable zone of the nearest star system and a key
test case in the search for extraterrestrial life. Here, we investigate the characterization of a …

The pyramid wave front sensor (PyWFS) has become increasingly popular to use in
adaptive optics (AO) systems due to its high sensitivity. The main drawback of the PyWFS is …

Context. Exomoons are expected to orbit gas giant exoplanets just as moons orbit Solar
System planets. Tidal heating is present in Solar System satellites, and it can heat up their …
