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-…
Types of Gaseous Envelopes of "Hot Jupiter" Exoplanets
D. V. Bisikalo, P. V. Kaigorodov, D. E. Ionov +1
As a rule, the orbital velocities of "hot Jupiters," i.e., exoplanets with masses comparable to the mass of Jupiter and orbital semi-major axes less than 0.1 AU, are supersonic rel…
3D Gas Dynamic Simulation of the Interaction Between the Exoplanet WASP-12b and Its Host Star
D. Bisikalo, P. Kaygorodov, D. Ionov +3
HST transit observations in the near-UV performed in 2009 made WASP-12b one of the most "mysterious" exoplanets; the system presents an early-ingress, which can be explained by the…
Gas dynamic simulation of the star-planet interaction using a binary star model
D. E. Ionov, D. V. Bisikalo, P. V. Kaygorodov +1
We have performed numerical simulations of the interaction between "hot Jupiter" planet and gas of the stellar wind using numerical code developed for investigations of binary star…
