Proton Irradiation of Primitive Atmospheres of Young Exoplanets and early Earth: Greenhouse Warming and Prebiotic Synthesis
Kensei Kobayashi, Vladimir S. Airapetian, Takumi Udo +8
The emergence of habitable conditions on the early Earth and on rocky exoplanets requires persistent energy sources that can drive both prebiotic chemistry and climate warming unde…
Venus as an Exoplanet: I. An Initial Exploration of the 3-D Energy Balance for a CO Exoplanetary Atmosphere Around an M-Dwarf Star
Christopher D. Parkinson, Stephen W. Bougher, Franklin P. Mills +5
The chemical evolution of an exoplanetary Venus-like atmosphere is dependent upon the ultraviolet to near ultraviolet (FUV-NUV) radiation ratio from the parent star, the balance be…
Atmospheric Escape Processes and Planetary Atmospheric Evolution
Guillaume Gronoff, Phil Arras, Suleiman M Baraka +17
The habitability of the surface of any planet is determined by a complex evolution of its interior, surface, and atmosphere. The electromagnetic and particle radiation of stars dri…
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…
Reconstructing Extreme Space Weather from Planet Hosting Stars
V. S. Airapetian, V. Adibekyan, M. Ansdell +80
The field of exoplanetary science is making rapid progress both in statistical studies of exoplanet properties as well as in individual characterization. As space missions provide…
EUV influences on exoplanet atmospheric stability and evolution
Allison Youngblood, Kevin France, Tommi Koskinen +15
The planetary effective surface temperature alone is insufficient to characterize exoplanet atmospheres and their stability or evolution. Considering the star-planet system as a wh…
Exploring Extreme Space Weather Factors of Exoplanetary Habitability
V. S. Airapetian, V. Adibekyan, M. Ansdell +46
It is currently unknown how common life is on exoplanets, or how long planets can remain viable for life. To date, we have a superficial notion of habitability, a necessary first s…
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…
