Exoplanet Exploration Program Analysis Group (ExoPAG) Report to Paul Hertz Regarding Large Mission Concepts to Study for the 2020 Decadal Survey
B. Scott Gaudi, Eric Agol, Daniel Apai +36
This is a joint summary of the reports from the three Astrophysics Program Analysis Groups (PAGs) in response to the "Planning for the 2020 Decadal Survey" charge given by the Astr…
Refraction in planetary atmospheres: improved analytical expressions and comparison with a new ray-tracing algorithm
Yan Betremieux, Lisa Kaltenegger
Atmospheric refraction affects to various degrees exoplanet transit, lunar eclipse, as well as stellar occultation observations. Exoplanet retrieval algorithms often use analytical…
Effect of UV Radiation on the Spectral Fingerprints of Earth-like Planets Orbiting M dwarfs
S. Rugheimer, L. Kaltenegger, A. Segura +2
We model the atmospheres and spectra of Earth-like planets orbiting the entire grid of M dwarfs for active and inactive stellar models with = 2300K to = 3800K a…
UV Surface Environment of Earth-like Planets Orbiting FGKM Stars Through Geological Evolution
S. Rugheimer, A. Segura, L. Kaltenegger +1
The UV environment of a host star affects the photochemistry in the atmosphere, and ultimately the surface UV environment for terrestrial planets and therefore the conditions for t…
Characterizing the Habitable Zones of Exoplanetary Systems with a Large Ultraviolet/Visible/Near-IR Space Observatory
Kevin France, Evgenya Shkolnik, Jeffrey Linsky +32
Understanding the surface and atmospheric conditions of Earth-size, rocky planets in the habitable zones (HZs) of low-mass stars is currently one of the greatest astronomical endea…
Characterising exoplanets and their environment with UV transmission spectroscopy
L. Fossati, V. Bourrier, D. Ehrenreich +36
Exoplanet science is now in its full expansion, particularly after the CoRoT and Kepler space missions that led us to the discovery of thousands of extra-solar planets. The last de…
