CAI formation in the early Solar System
P. Woitke, J. Drażkowska, H. Lammer +2
Ca-Al-rich inclusions (CAIs) are the oldest dated solid materials in the solar system, found as light-coloured crystalline ingredients in meteorites. Their formation time is common…
On the required mass for exoplanetary radio emission
Jean-Mathias Grießmeier, N. V. Erkaev, C. Weber +3
The detection of radio emission from an exoplanet would constitute the best way to determine its magnetic field. Indeed, the presence of a planetary magnetic field is a necessary c…
Three-dimensional modelling of absorption by various species for hot Jupiter HD 209458b
I F Shaikhislamov, M L Khodachenko, H Lammer +3
The absorption of stellar radiation observed by the HD209458b in resonant lines of OI and CII has not yet been satisfactorily modeled. In our previous 2D simulations we have shown…
Solar XUV and ENA-driven water loss from early Venus' steam atmosphere
H. I. M. Lichtenegger, K. G. Kislyakova, P. Odert +8
The influence of the hydrogen hydrodynamic upper atmosphere escape, driven by the solar soft X-ray and extreme ultraviolet radiation (XUV) flux, on an expected magma ocean outgasse…
3D Aeronomy Modeling of Close-in Exoplanets
I. F. Shaikhislamov, M. L. Khodachenko, H. Lammer +3
We present a 3D fully selfconsistent multi-fluid hydrodynamic aeronomy model to study the structure of a hydrogen dominated expanding upper atmosphere around the hot Jupiter HD 209…
A grid of upper atmosphere models for 1--40 MEARTH planets: application to CoRoT-7 b and HD219134 b,c
Daria Kubyshkina, Luca Fossati, Nicolay V. Erkaev +5
There is growing observational and theoretical evidence suggesting that atmospheric escape is a key driver of planetary evolution. Commonly, planetary evolution models employ simpl…
