    • Abiotic ozone and oxygen in atmospheres similar to prebiotic earth 

      Domagal-Goldman, S.D.; Segura, A.; Claire, M.W.; Robinson, T.D.; Meadows, V.S. (2014-09-10) - Journal article
      The search for life on planets outside our solar system will use spectroscopic identification of atmospheric biosignatures. The most robust remotely detectable potential biosignature is considered to be the detection of ...
    • Lightning chemistry on Earth-like exoplanets 

      Ardaseva, Aleksandra; Rimmer, Paul B.; Waldmann, Ingo; Rocchetto, Marco; Yurchenko, Sergey N.; Helling, Christiane; Tennyson, Jonathan (2017-08) - Journal article
      We present a model for lightning shock-induced chemistry that can be applied to atmospheres of arbitrary H/C/N/O chemistry, hence for extrasolar planets and brown dwarfs. The model couples hydrodynamics and the STAND2015 ...
    • UV surface environment of Earth-like planets orbiting FGKM stars through geological evolution 

      Rugheimer, S.; Segura, A.; Kaltenegger, L.; Sasselov, D. (2015-06-12) - Journal article
      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 the origin and evolution of life. We model ...
