P006:
Planetary Habitability and the Main Control Factors.





Session ID#: 25016

Session Description:
This session addresses the broad question of what a planet needs to enable life as we know it to thrive. Is a solar-type star required? with a particular electromagnetic spectrum? Does a planet need a magnetic field to sustain an atmosphere? Is an atmosphere or a magnetic field more efficient at deflecting penetrating radiation and cosmic rays? Are tides required and therefore a moon? Does a solar system need a Jupiter-like planet to protect inner planets? We invite abstracts related to these topics in general and in particular: 1) relevant phenomena at Earth, for example atmospheric stripping, polar wind, auroral heating, magnetosphere-ionosphere coupling; 2) how do solar system objects like Venus and Titan sustain robust (but apparently uninhabitable) atmospheres despite having no magnetic field; 3) where on Mars might life still be found and why and 4) which exoplanets are most likely to sustain an habitable atmosphere?
