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

Low-mass stars show evidence of vigorous magnetic activity in the form of large flares and
coronal mass ejections. Such space weather events may have important ramifications for the …

Most definitions of life assume that, at a minimum, life is a physical form of matter distinct
from its environment at a lower state of entropy than its surroundings, using energy from the …

Atmospheric characterization of temperate, rocky planets is the holy grail of exoplanet
studies. These worlds are at the limits of our capabilities with current instrumentation in …

A planetary atmosphere is the outer gas layer of a planet. Besides its scientific significance
among the first and most accessible planetary layers observed from space, it is closely …

Abstract The nearby exoplanet Proxima Centauri b will be a prime future target for
characterization, despite questions about its retention of water. Climate models with static …

The era of atmospheric characterization of terrestrial exoplanets is just around the corner.
Modeling prior to observations is crucial in order to predict the observational challenges and …

Context. With seven planets, the TRAPPIST-1 system has among the largest number of
exoplanets discovered in a single system so far. The system is of astrobiological interest …

We present a large ensemble of simulations of an Earth-like world with increasing insolation
and rotation rate. Unlike previous work utilizing idealized aquaplanet configurations, we …

Low-mass stars are currently the most promising targets for detecting and characterizing
habitable planets in the solar neighborhood. However, the ultraviolet (UV) radiation emitted …
