Speaker: Salvatore Colombo Titolo: “Radiation hydrodynamic and magnetohydrodynamic models of plasma flows accreting onto Classical T Tauri Stars” Abstract: “Secondo lo scenario più accettato, le stelle T Tauri sono stelle giovani che accrescono massa dal loro disco circumstellare. L’obiettivo del mio dottorato è stato quello di studiare il fenomeno di accrescimento di massa in questi sistemi. Durante il mio seminario

 

Speaker: A. Garrido (UNIPA) Titolo: Analysis of exoplanetary atmospheres. Abstract: The seminar summarizes the work of my last PhD year. During the talk I will explain how to obtain an atmospheric transmission spectrum of a transit exoplanet: Kelt-9b. The analyzes carried out will be explained and finally I will show the Balmer lines of the exoplanet’s atmosphere. The seminar concludes with the derivation

Speaker:  Darius Modirrousta Galian Titolo: Theoretical exoplanetology Seminario: Why does 55 Cancri e have a H/H 2 -rich atmosphere? Why is there a bimodal distribution of exoplanet radii with one peak at ~ 1.3R ⨁ , the other and ~ 2.4R ⨁ , and the minima at ~ 1.8R ⨁ . Why do some airless magma ocean super-Earths have albedos close
