Basic Solar Physics Seminars (extra) - Solar Irradiance and upper planetary atmospheres

by Gaël Cessateur

Friday, 18 May 2018 from to (Europe/Brussels)
at Meridian Room
Description
The solar UV radiation is responsible for the photo-ionization and photo-dissociation processes within planetary and cometary atmospheres. In the framework of planetary space weather, there is nowadays a real need for monitoring the solar UV for a various range of timescales. 
After a quick review how we can retrieve the solar UV irradiance from a theoretical point of view, I will present different models of photo-excitation in the case of moons and comets, for different solar activities. Atmospheric emissions are indeed a signature of the solar UV impact, and are interesting tools for space weather.
