Origin and Evolution of Cosmic PAHs: Tracing Molecular Content of Dust Analogs, Meteorites and Asteroids

Soutenance de HDR de Hassan Sabbah (Salle de Conférence) Résumé de la HDR Large carbonaceous molecules such as polycyclic aromatic hydrocarbons (PAHs) and fullerenes are prevalent in astrophysical environments.They play a significant role in the physics and chemistry of regions where stars and planets form. The investigation into the formation of specific molecules within these families, […]

A viewpoint on modeling stellar atmospheres and their impact on planets

Salle Lyot - IRAP Belin 14 avenue Edouard Belin, Toulouse, FR

Andrea Chiavassa - Lagrande, Nice Stars exhibit intricate and stochastic patterns on their surfaces due to convective heat transport, known as granulation. Convection manifests in the surface layers as a particular pattern of downflowing cooler plasma and bright areas where hot plasma rises. Convection is a difficult process to understand, because it is non-local and […]

The Past, Present, and Future of Asteroid Exploration

Salle de Conférence - IRAP Roche 9 avenue du Colonel Roche, Toulouse, FR

Jay McMahon - UC Boulder In this talk I will briefly review the past missions to asteroids including NEAR, Hayabusa, Dawn, and Hayabusa2. I will then delve a bit deeper talking about OSIRIS-REx and DART - two recent NASA missions that I was a part of. For each of these missions, I will show some […]
