The EXO-UV program: lastest advances of experimental studies to investigate the biological impact of UV radiation on exoplanets
Ximena C. Abrevaya, Petra Odert, Oscar J. Oppezzo +4
The EXO-UV program is an international, interdisciplinary collaboration between astrophysicists and biologists aimed at expanding the characterization of ultraviolet radiation (UVR…
Protective Effects of Halite to Vacuum and Vacuum-Ultraviolet Radiation: A Potential Scenario During a Young Sun Superflare
Ximena C. Abrevaya, Douglas Galante, Paula M. Tribelli +16
Halite (NaCl mineral) has exhibited the potential to preserve microorganisms for millions of years on Earth. This mineral was also identified on Mars and in meteorites. In this stu…
Modification of the radioactive heat budget of Earth-like exoplanets by the loss of primordial atmospheres
N. Erkaev, M. Scherf, O. Herbort +6
The initial abundance of radioactive heat producing isotopes in the interior of a terrestrial planet are important drivers of its thermal evolution and the related tectonics and po…
Formation of Venus, Earth and Mars: Constrained by isotopes
H. Lammer, R. Brasser, A. Johansen +2
We discuss the current state of knowledge of terrestrial planet formation from the aspects of different planet formation models and isotopic data from 182Hf-182W, U-Pb, lithophile-…
Modeling the Ly transit absorption of the hot Jupiter HD 189733b
P. Odert, N. V. Erkaev, K. G. Kislyakova +7
Hydrogen-dominated atmospheres of hot exoplanets expand and escape due to the intense heating by the X-ray and extreme ultraviolet (XUV) irradiation of their host stars. Excess abs…
Escape and fractionation of volatiles and noble gases from Mars-sized planetary embryos and growing protoplanets
P. Odert, H. Lammer, N. V. Erkaev +6
Planetary embryos form protoplanets via mutual collisions, which can lead to the development of magma oceans. During their solidification, large amounts of the mantles' volatile co…
