22. Modelling exoplanet atmospheres to interpret GIANO observations

Matteo Brogi (University of Warwick)

05/05/2020, 14:30

Near-infrared high-resolution spectroscopy relies on cross correlation with model spectra to extract information about the chemical and physical conditions of exoplanet atmospheres. In this talk I will review recent efforts to identify the most reliable molecular line lists applicable to simulate the high temperatures of extrasolar planets. Furthermore, I will explain how GIANO could be used...

3. Understanding the XUV-induced Atmospheric Erosion of Young Planets and their Evolution With Time

Darius Modirrousta Galian (Istituto Nazionale di Astrofisica (INAF))

In the talk we will discuss the effects of X-ray and ultraviolet radiation on atmospheric erosion around young stars. Specifically, we focus on the bimodal distribution of exoplanet radii (i.e. “The Fulton Gap”; Fulton et al. 2017). In Modirrousta-Galian et al. (2020,b) this distribution is theoretically analysed in order to make several predictions that can be astronomically tested. For...

34. Evaporation models and the importance of determining the parameters of young planets

Daniele Locci

The knowledge of planetary mass and radius of young planets is crucial in the understanding if their atmospheres can survive at the intense XUV stellar irradiation
