The Habitability of Proxima Centauri b: Environmental States and Observational Discriminants
Lustig-Yaeger, Jacob; Meadows, Victoria S.; Arney, Giada N. +11 more
Proxima Centauri b provides an unprecedented opportunity to understand the evolution and nature of terrestrial planets orbiting M dwarfs. Although Proxima Cen b orbits within its star's habitable zone, multiple plausible evolutionary paths could have generated different environments that may or may not be habitable. Here, we use 1-D coupled climat…
Clathrate Hydrates of Oxidants in the Ice Shell of Europa
Hand, Kevin P.; Carlson, Robert W.; Cooper, John F. +1 more
Europa's icy surface is radiolytically modified by high-energy electrons and ions, and photolytically modified by solar ultraviolet photons. Observations from the Galileo Near Infrared Mapping Spectrometer, ground-based telescopes, the International Ultraviolet Explorer, and the Hubble Space Telescope, along with laboratory experiment results, ind…
