A very early origin of isotopically distinct nitrogen in inner Solar System protoplanets
Damanveer S. Grewal, Rajdeep Dasgupta, Bernard Marty
Understanding the origin of life-essential volatiles like N in the Solar System and beyond is critical to evaluate the potential habitability of rocky planets. Whether the inner So…
A 4565 Myr old andesite from an extinct chondritic protoplanet
Jean-Alix Barrat, Marc Chaussidon, Akira Yamaguchi +5
The age of iron meteorites implies that accretion of protoplanets began during the first millions of years of the solar system. Due to the heat generated by 26Al decay, many early…
Loss and fractionation of noble gas isotopes and moderately volatile elements from planetary embryos and early Venus, Earth and Mars
H. Lammer, M. Scherf, H. Kurokawa +12
Here we discuss the current state of knowledge on how atmospheric escape processes can fractionate noble gas isotopes and moderately volatile rock-forming elements that populate pr…
Is the faint young Sun problem for Earth solved?
Benjamin Charnay, Eric T. Wolf, Bernard Marty +1
Stellar evolution models predict that the solar luminosity was lower in the past, typically 20-25 % lower during the Archean (3.8-2.5 Ga). Despite the fainter Sun, there is strong…
Perspectives on atmospheric evolution from noble gas and nitrogen isotopes on Earth, Mars & Venus
Guillaume Avice, Bernard Marty
The composition of an atmosphere has integrated the geological history of the entire planetary body. However, the long-term evolutions of the atmospheres of the terrestrial planets…
Chemistry under EUV Irradiation of H-CO-N Gas Mixtures: Implications for Photochemistry in the Outer CSE of Evolved Stars
Jérémy Bourgalais, David V. Bekaert, Aurore Bacmann +2
{CircumStellar Envelopes (CSEs) of stars are complex chemical objects for which theoretical models encounter difficulties in elaborating a comprehensive overview of the occurring c…
