Comparative Analysis of the Model for Exoplanet Atmosphere Outflow
P. B. Isakova, Ya. N. Pavlyuchenkov, E. S. Kalinicheva +1
Modeling the outflow of planetary atmospheres is important for understanding the evolution of exoplanet systems and for interpreting their observations. Modern theoretical models o…
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…
Hot oxygen and carbon escape from the martian atmosphere
Hannes Gröller, Herbert Lichtenegger, Helmut Lammer +1
The escape of hot O and C atoms from the present martian atmosphere during low and high solar activity conditions has been studied with a Monte-Carlo model. The model includes the…
Survival of a planet in short-period Neptunian desert under effect of photo-evaporation
Dmitry E. Ionov, Yaroslav N. Pavlyuchenkov, Valery I. Shematovich
Despite the identification of a great number of Jupiter-like and Earth-like planets at close-in orbits, the number of "hot Neptunes" - the planets with 0.6-18 times of Neptune mass…
Influence of Photoelectrons on the Structure and Dynamics of the Upper Atmosphere of a Hot Jupiter
D. E. Ionov, V. I. Shematovich, Ya. N. Pavlyuchenkov
A self-consistent, aeronomic model of the upper atmosphere of a "hot Jupiter" including reactions involving suprathermal photoelectrons is presented. This model is used to compute…
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-…
