P43H:
Impacts of Space Weather from the Sun and Active Stars on Atmospheric Evolution of Terrestrial (Exo)Planets I Posters


Submit an Abstract to this Session


Session ID#: 52982

Session Description:
Recent explosion of the discovered terrestrial exoplanets around active G-M dwarfs raises a fundamental question about how to detect habitable worlds. Recently detected superflares on late-type stars and associated space weather in the form of XUV emission, coronal mass ejection and solar energetic particle events can cause atmospheric erosion and chemical changes. These factors may present significant challenges for surface habitability. The proposed session invites theoretical, observational and laboratory studies that shed light on factors of atmospheric ion and neutral escape from the current and early Earth, Mars and exoplanetary atmospheres including chemical changes due to various factors of space weather.

Bioorganic compound survivability against γ radiation on Mars&5 cm below with a dose corresponding to 500000 years were studied: Organic compound lost due to gamma radiation is about 90% for samples on the surface, while only about 10% for samples located 5 cm below the surface: Results demonstrate the organic accumulation instead of organic lost.
