Seven rocky planets orbit the nearby dwarf star TRAPPIST-1, providing a unique opportunity
to search for atmospheres on small planets outside the Solar System. Thanks to the recent …

Here we examine how our knowledge of present day Venus can inform terrestrial
exoplanetary science and how exoplanetary science can inform our study of Venus. In a …

OVERVIEW Nearly 30 years after the discovery of the first exoplanet around a main
sequence star, thousands of planets have now been confirmed. These discoveries have …

In recent years, the discovery of increasing numbers of rocky, terrestrial exoplanets orbiting
nearby stars has drawn increased attention to the possibility of studying these planets' …

Abstract During its 2 yr Prime Mission, TESS observed over 232,000 stars at a 2 minute
cadence across∼ 70% of the sky. These data provide a record of photometric variability …

Oxygen is a promising exoplanet biosignature due to the evolutionary advantage conferred
by harnessing starlight for photosynthesis, and the apparent low likelihood of maintaining …

Short-period exoplanets on circular orbits are thought to be tidally locked into synchronous
rotation. If tidally locked, these planets must possess permanent day-and night-sides, with …

Transiting planets orbiting M dwarfs provide the best opportunity to study the atmospheres of
rocky planets with current facilities. As JWST enters its second year of science operations …

The extreme environments of ultra-short-period planets (USPs) make excellent laboratories
to study how exoplanets obtain, lose, retain, and/or regain gaseous atmospheres. We …

Over the past several decades, thousands of planets have been discovered outside our
Solar System. These planets exhibit enormous diversity, and their large numbers provide a …
