M Star Astrosphere Size Fluctuations and Habitable Planet Descreening
David S. Smith, John M. Scalo
Stellar astrospheres--the plasma cocoons carved out of the interstellar medium by stellar winds--are continually influenced by their passage through the fluctuating interstellar me…
Risks due to X-ray Flares during Astronaut Extravehicular Activity
David S. Smith, John M. Scalo
Solar hard X-ray flares can expose astronauts on lunar and deep space extravehicular activities (EVAs) to dangerous acute biological doses. We combine calculations of radiative tra…
Solar X-ray Flare Hazards on the Surface of Mars
David S. Smith, John M. Scalo
Putative organisms on the Martian surface would be exposed to potentially high doses of ionizing radiation during strong solar X-ray flares. We extrapolate the observed flare frequ…
Transport of Ionizing Radiation in Terrestrial-like Exoplanet Atmospheres
David S. Smith, John Scalo, J. Craig Wheeler
(Abridged) The propagation of ionizing radiation through model atmospheres of terrestrial-like exoplanets is studied for a large range of column densities and incident photon energ…
