3D Numerical Model for Studying Electron Precipitation in the Upper Atmospheres of Venus-Like Exoplanets

In the paper, a three-dimensional numerical model of solar wind plasma flow around a terrestrial planet that does not have its own magnetic field has been present. The model has been based on the approximation of multicomponent magnetohydrodynamics and has taken into account ionization and recombination processes. The numerical model has been validated using the example of the magnetosphere of Venus. Our model, in particular, has made it possible to calculate the structure and parameters of electron precipitation into the planet’s ionosphere. The developed model has been supposed to be used to study observational manifestations of the NO potential biomarker in the atmospheres of exoplanets without their own magnetic field.
