Modeling Solar Proton Event-induced Martian Surface Radiation Dose
Dimitra Atri, Caitlin MacArthur, Ian Dobbs-Dixon
Solar Proton Events (SPEs) can cause abrupt and significant enhancements to the Martian surface radiation dose. Observations of the impact of SPEs on the Martian surface are availa…
From Starspots to Stellar Coronal Mass Ejections -- Revisiting Empirical Stellar Relations
Konstantin Herbst, Athanasios Papaioannou, Vladimir S. Airapetian +1
Upcoming missions, including the James Webb Space Telescope, will soon characterize the atmospheres of terrestrial-type exoplanets in habitable zones around cool K- and M-type star…
Gamma Ray Bursts: Not so Much Deadlier than We Thought
Brian C. Thomas, Dimitra Atri, Adrian L. Melott
We analyze the additional effect on planetary atmospheres of recently detected gamma-ray burst afterglow photons in the range up to 1 TeV. For an Earth-like atmosphere we find that…
Stellar Flares versus Luminosity: XUV-induced Atmospheric Escape and Planetary Habitability
Dimitra Atri, Shane R. Carberry Mogan
Space weather plays an important role in the evolution of planetary atmospheres. Observations have shown that stellar flares emit energy in a wide energy range (10^30-10^38 ergs),…
Investigating the biological potential of galactic cosmic ray-induced radiation-driven chemical disequilibrium in the Martian subsurface environment
Dimitra Atri
There is growing evidence suggesting the presence of aqueous environment on ancient Mars, raising the question of the possibility of life in such an environment. Subsequently, with…
