Biomarker Response to Galactic Cosmic Ray-Induced NOx and the Methane Greenhouse Effect in the Atmosphere of an Earthlike Planet Orbiting an M-Dwarf Star
John Lee Grenfell, Jean-Mathias Griessmeier, Beate Patzer +6
Planets orbiting in the habitable zone (HZ) of M-Dwarf stars are subject to high levels of galactic cosmic rays (GCRs) which produce nitrogen oxides in earthlike atmospheres. We in…
Spectral signatures of photosynthesis II: coevolution with other stars and the atmosphere on extrasolar worlds
Nancy Y. Kiang, Antigona Segura, Giovanna Tinetti +6
As photosynthesis on Earth produces the primary signatures of life that can be detected astronomically at the global scale, a strong focus of the search for extrasolar life will be…
The Response of Atmospheric Chemistry on Earthlike Planets around F, G and K Stars to Small Variations in Orbital Distance
John Lee Grenfell, Barbara Stracke, Philip von Paris +4
One of the prime goals of future investigations of extrasolar planets is to search for life as we know it. The Earth's biosphere is adapted to current conditions. How would the atm…
A Re-appraisal of the Habitability of Planets Around M Dwarf Stars
Jill C. Tarter, Peter R. Backus, Rocco L. Mancinelli +29
Stable, hydrogen-burning, M dwarf stars comprise about 75% of all stars in the Galaxy. They are extremely long-lived and because they are much smaller in mass than the Sun (between…
Biosignatures from Earth-Like Planets Around M Dwarfs
Antigona Segura, James F. Kasting, Victoria Meadows +5
Coupled one-dimensional photochemical-climate calculations have been performed for hypothetical Earth-like planets around M dwarfs. Visible, near-infrared and thermal-infrared synt…
