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 field of exoplanet atmospheric characterization has recently made considerable
advances with the advent of high-resolution spectroscopy from large ground-based …

The TRAPPIST-1 system is remarkable for its seven planets that are similar in size, mass,
density and stellar heating to the rocky planets Venus, Earth and Mars in the Solar System …

Planets orbiting M-dwarf stars are prime targets in the search for rocky exoplanet
atmospheres. The small size of M dwarfs renders their planets exceptional targets for …

The critical first step in the search for life on exoplanets over the next decade is to determine
whether rocky planets transiting small M-dwarf stars possess atmospheres and, if so, what …

We have collected transit times for the TRAPPIST-1 system with the Spitzer Space
Telescope over four years. We add to these ground-based, HST, and K2 transit-time …

TRAPPIST-1 is a nearby system of seven Earth-sized, temperate, rocky exoplanets transiting
a Jupiter-sized M8. 5V star, ideally suited for in-depth atmospheric studies. Each TRAPPIST …

Abstract The James Webb Space Telescope (JWST) will offer the first opportunity to
characterize terrestrial exoplanets with sufficient precision to identify high mean molecular …

In the past decade, observations from space and the ground have found water to be the
most abundant molecular species, after hydrogen, in the atmospheres of hot, gaseous …

Observations of exoplanet atmospheres have shown that aerosols, like in the solar system,
are common across a variety of temperatures and planet types. The formation and …
