Exoplanet Habitability: A Cross-Disciplinary Perspective from the 2017 AGU Fall Meeting
To the point
Giada Arney, Stephen Kane, Katherine Garcia-Sage, and David Brain say that identifying truly habitable exoplanets requires a cross-disciplinary, holistic approach that combines astrophysics, Earth science, heliophysics, and planetary science, uses direct imaging and solar-system analogs to test models, and acknowledges that many planets in the habitable zone may still be uninhabitable due to magnetic fields, stellar radiation, space weather, and atmospheric loss.
