Global 3D simulation of the upper atmosphere of HD189733b and absorption in metastable HeI and Lyα lines
M. S. Rumenskikh, I. F. Shaikhislamov, M. L. Khodachenko +4
A 3D fully self-consistent multi-fluid hydrodynamic aeronomy model is applied to simulate the hydrogen-helium expanding upper atmosphere of the hot Jupiter HD189733b, and related a…
The Exosphere as a Boundary: Origin and Evolution of Airless Bodies in the Inner Solar System and Beyond Including Planets with Silicate Atmospheres
H. Lammer, M. Scherf, Y. Ito +6
In this review we discuss all the relevant solar/stellar radiation and plasma parameters and processes that act together in the formation and modification of atmospheres and exosph…
Escape and evolution of Mars' CO2 atmosphere: Influence of suprathermal atoms
U. V. Amerstorfer, H. Gröller, H. Lichtenegger +7
With a Monte-Carlo model we investigate the escape of hot oxygen and carbon from the martian atmosphere for four points in time in its history corresponding to 1, 3, 10, and 20 tim…
An Overabundance of Low-density Neptune-like Planets
Patricio Cubillos, Nikolai V. Erkaev, Ines Juvan +6
We present a uniform analysis of the atmospheric escape rate of Neptune-like planets with estimated radius and mass (restricted to ). For each planet we c…
Magnetic moment and plasma environment of HD 209458b as determined from Ly observations
K. G. Kislyakova, M. Holmström, H. Lammer +2
Transit observations of HD 209458b in the stellar Lyman- (Ly) line revealed strong absorption in both blue and red wings of the line interpreted as hydrogen atoms escaping fr…
Heating efficiency in hydrogen-dominated upper atmospheres
Valery I. Shematovich, Dmitry E. Ionov, Helmut Lammer
Context. The heating efficiency is defined as the ratio of the net local gas-heating rate to the rate of stellar radiative energy absorption. It plays an important role in thermal-…
