Martin Turbet - LAB, Bordeaux La Terre, Vénus et Mars ont aujourd'hui des atmosphères et climats en apparence radicalement différents. Alors que la Terre possède les conditions idéales pour maintenir des océans, mers et lacs d'eau liquide, Vénus est une véritable fournaise, et Mars un monde glacial. Mais en a-t-il toujours été ainsi ? Quand […]
Benjamin Crinquant - IRAP A variety of astrophysical phenomena can only be explained as being powered by black holes. Black-hole activity can manifest itself through the launching of a relativistic jet, or the production of short, intense gamma-ray flares. Recent progress in instrumentation has allowed us to probe these processes with unprecedented detail. For example, […]
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, […]
Andrea Chiavassa - Lagrange, 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 […]
