In the coming years and decades, advanced space-and ground-based observatories will
allow an unprecedented opportunity to probe the atmospheres and surfaces of potentially …

Rocky planets are common around other stars, but their atmospheric properties remain
largely unconstrained. Thanks to a wealth of recent planet discoveries and upcoming …

The search for life in the Universe is a fundamental problem of astrobiology and modern
science. The current progress in the detection of terrestrial-type exoplanets has opened a …

In recent years, the advent of a new generation of radial velocity instruments has allowed us
to detect planets with increasingly lower mass and to break the one Earth-mass barrier. Here …

The TRAPPIST-1 planetary system provides an unprecedented opportunity to study
terrestrial exoplanet evolution with the James Webb Space Telescope (JWST) and ground …

Exoplanet hunting efforts have revealed the prevalence of exotic worlds with diverse
properties, including Earth-sized bodies, which has fueled our endeavor to search for life …

The presence of an atmosphere over sufficiently long timescales is widely perceived as one
of the most prominent criteria associated with planetary surface habitability. We address the …

TRAPPIST-1 planets are invaluable for the study of comparative planetary science outside
our solar system and possibly habitability. Both transit timing variations (TTV) of the planets …

Mass-radius relationships for water-rich rocky planets are usually calculated assuming most
water is present in condensed (either liquid or solid) form. Planet density estimates are then …

We present the discovery of an Earth-mass planet (M b sin i= 1.26±0.21 M⊕) on a 15.6 d
orbit of a relatively nearby (d~ 9.6 pc) and low-mass (0.167±0.011 M⊙) M5. 0 V star, Wolf …
