TRAPPIST-1 is a fantastic nearby (∼ 39.14 light years) planetary system made of at least
seven transiting terrestrial-size, terrestrial-mass planets all receiving a moderate amount of …

The habitable zone (HZ) is the circular region around a star (s) where standing bodies of
water could exist on the surface of a rocky planet. Space missions employ the HZ to select …

Context. The TRAPPIST-1 system hosts seven Earth-sized, temperate exoplanets orbiting an
ultra-cool dwarf star. As such, it represents a remarkable setting to study the formation and …

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

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 …

The Cosmic Shoreline: The Evidence that Escape Determines which Planets Have
Atmospheres, and what this May Mean for Proxima Centauri B - IOPscience Skip to content IOP …

Context. Recently, the He I triplet at 10 830 Å was rediscovered as an excellent probe of the
extended and possibly evaporating atmospheres of close-in transiting planets. This has …

TRAPPIST-1 is a nearby 0.08 M⊙ M-star that was recently found to harbor a planetary
system of at least seven Earth-sized planets, all within 0.1 au. The configuration confounds …

We analyze the K2 light curve of the TRAPPIST-1 system. The Fourier analysis of the data
suggests P rot= 3.295±0.003 days. The light curve shows several flares, of which we …

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 …
