Impact of Space Weather on Climate and Habitability of Terrestrial Type Exoplanets
V. S. Airapetian, R. Barnes, O. Cohen +43
The current progress in the detection of terrestrial type exoplanets has opened a new avenue in the characterization of exoplanetary atmospheres and in the search for biosignatures…
Atmospheric reconnaissance of the habitable-zone Earth-sized planets orbiting TRAPPIST-1
J. de Wit, H. R. Wakeford, N. Lewis +14
Seven temperate Earth-sized exoplanets readily amenable for atmospheric studies transit the nearby ultracool dwarf star TRAPPIST-1 (refs 1,2). Their atmospheric regime is unknown a…
Life Beyond the Solar System: Space Weather and Its Impact on Habitable Worlds
V. S. Airapetian, W. C. Danchi, C. F. Dong +33
The search of life in the Universe is a fundamental problem of astrobiology and a major priority for NASA. A key area of major progress since the NASA Astrobiology Strategy 2015 (N…
Temporal evolution of the high-energy irradiation and water content of TRAPPIST-1 exoplanets
V. Bourrier, J. de Wit, E. Bolmont +13
The ultracool dwarf star TRAPPIST-1 hosts seven Earth-size transiting planets, some of which could harbour liquid water on their surfaces. UV observations are essential to measure…
A map of the large day-night temperature gradient of a super-Earth exoplanet
Brice-Olivier Demory, Michael Gillon, Julien de Wit +11
Over the past decade, observations of giant exoplanets (Jupiter-size) have provided key insights into their atmospheres, but the properties of lower-mass exoplanets (sub-Neptune) r…
Searching for Terrestrial Planets Orbiting in the Habitable Zone of Ultra-Cool Stars and Brown Dwarfs
Brice-Olivier Demory, Sara Seager, Jack Lissauer +11
We propose to use Kepler in 2-wheel mode to conduct a detailed search for Earth-sized planets orbiting ultra-cool stars and brown dwarfs (spectral types from M7 to L3). This popula…
Towards the Minimum Inner Edge Distance of the Habitable Zone
Andras Zsom, Sara Seager, Julien de Wit +1
We explore the minimum distance from a host star where an exoplanet could potentially be habitable in order not to discard close-in rocky exoplanets for follow-up observations. We…
