Life as the Only Reason for the Existence of N2-O2-Dominated Atmospheres
Laurenz Sproß, Manuel Scherf, Valery I. Shematovich +2
The Earth's N2-dominated atmosphere is a very special feature. Firstly, N2 as main gas is unique on the terrestrial planets in the inner solar system and gives a hint for tectonic…
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-…
Did Mars possess a dense atmosphere during the first ~400 million years?
M. Scherf, H. Lammer
It is not yet entirely clear whether Mars began as a warm and wet planet that evolved towards the present-day cold and dry body or if it always was cold and dry with just some spor…
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…
Nitrogen Atmospheres of the Icy Bodies in the Solar System
M. Scherf, H. Lammer, N. V. Erkaev +3
This brief review will discuss the current knowledge on the origin and evolution of the nitrogen atmospheres of the icy bodies in the solar system, particularly of Titan, Triton an…
Escape and evolution of Titan's N atmosphere constrained by N/N isotope ratios
N. V. Erkaev, M. Scherf, S. E. Thaller +4
We apply a 1D upper atmosphere model to study thermal escape of nitrogen over Titan's history. Significant thermal escape should have occurred very early for solar EUV fluxes 100 t…
