The ultra-hot Jupiter KELT-9b forces us to reconsider existing models of the upper atmospheres of hot exoplanets, which were previously developed using the example of G or M star systems such as HD209458b and GJ436b. The unique conditions for the interaction of the radiation of an A-class star with the atmosphere necessitate kinetic modeling of excited levels of elements, primarily the hydrogen atom. For KELT-9b, absorption was recorded for several lines of hydrogen and lines of a number of heavy elements, the quantitative interpretation of which is an urgent task. In this work, for the first time, 3D modeling of the atmosphere of a planet with a close location of the Roche lobe has been implemented, taking into account the aeronomy, kinetics of excited hydrogen and several lines of heavy elements.
期刊介绍：
Solar System Research publishes articles concerning the bodies of the Solar System, i.e., planets and their satellites, asteroids, comets, meteoric substances, and cosmic dust. The articles consider physics, dynamics and composition of these bodies, and techniques of their exploration. The journal addresses the problems of comparative planetology, physics of the planetary atmospheres and interiors, cosmochemistry, as well as planetary plasma environment and heliosphere, specifically those related to solar-planetary interactions. Attention is paid to studies of exoplanets and complex problems of the origin and evolution of planetary systems including the solar system, based on the results of astronomical observations, laboratory studies of meteorites, relevant theoretical approaches and mathematical modeling. Alongside with the original results of experimental and theoretical studies, the journal publishes scientific reviews in the field of planetary exploration, and notes on observational results.
