Transiting Exoplanet Survey Satellite (TESS) [PDF]
Astronomical Telescopes and Instrumentation, 2014 The Transiting Exoplanet Survey Satellite (TESS ) will search for planets transiting bright and nearby stars. TESS has been selected by NASA for launch in 2017 as an Astrophysics Explorer mission. The spacecraft will be placed into a highly elliptical 13.

Efficient metal emissions in the upper atmospheres of close-in exoplanets
Earth and Planetary Physics, 2018 Atmospheric escape is a key process controlling the long term evolution of planets. Radiative cooling competes for energy against atmospheric escape in planetary upper atmospheres.

Detection of an Atmosphere on a Rocky Exoplanet [PDF]
Astronomical Journal, 2021 We report the detection of an atmosphere on a rocky exoplanet, GJ 1132 b, which is similar to Earth in terms of size and density. The atmospheric transmission spectrum was detected using Hubble WFC3 measurements and shows spectral signatures of aerosol ...

Frontiers in Astronomy and Space Sciences, 2021 In the search for life on other planets, the presence of photosynthetic surface vegetation may be detectable from the colors of light it reflects. On the modern Earth, this spectral reflectance is characterized by a steep increase in reflectance between ...

Oxygen False Positives on Habitable Zone Planets Around Sun‐Like Stars
AGU Advances, 2021 Oxygen is a promising exoplanet biosignature due to the evolutionary advantage conferred by harnessing starlight for photosynthesis, and the apparent low likelihood of maintaining oxygen‐rich atmospheres without life.

A Guide to Realistic Uncertainties on the Fundamental Properties of Solar-type Exoplanet Host Stars [PDF]
Astrophysical Journal, 2020 Our understanding of the properties and demographics of exoplanets critically relies on our ability to determine the fundamental properties of their host stars. The advent of Gaia and large spectroscopic surveys has now made it possible, in principle, to
