The dozens of rocky exoplanets discovered in the circumstellar habitable zone (CHZ)
currently represent the most suitable places to host life as we know it outside the Solar …

Context. Small planets located at the lower mode of the bimodal radius distribution are
generally assumed to be composed of iron and silicates in a proportion similar to that of the …

Context. The current architecture of a given multi-planetary system is a key fingerprint of its
past formation and dynamical evolution history. Long-term follow-up observations are key to …

Context. The Neptunian desert and savanna have recently been found to be separated by a
ridge, an overdensity of planets in the period range of≃ 3–5 days. These features are …

The main scientific goal of TESS is to find planets smaller than Neptune around stars that
are bright enough to allow for further characterization studies. Given our current …

Context. The next generation of space-based observatories will characterize the
atmospheres of low-mass, temperate exoplanets with the direct-imaging technique. This will …

ABSTRACT For stars hosting Circumstellar Habitable Zone (CHZ) exoplanets, we
investigate the time evolution of their ultraviolet habitable zone (UHZ), the annular region …

Context. The transit technique has been very efficient over the past decades in detecting
planet-candidate signals. The so-called statistical validation approach has become a …

Fuelled by space photometry, asteroseismology is vastly benefitting the study of cool main-
sequence stars, which exhibit convection-driven solar-like oscillations. Even so, the tiny …

Context. Planetary systems with close-in giant planets can experience magnetic star-planet
interactions that modify the activity levels of their host stars. The induced activity is known to …
