le 17 novembre 2023, 10h45 à 12h45, Guillaume Loizelet, salle Jules Verne, OMP, site Belin Resumé: It is not possible to develop a mathematical model without a reliable and consistent database.In this session, I will first detail the cultural context that led the Babylonian « astronomers » to establish formidable data collections in the form of clay tablets. […]
le 10 novembre 2023, 10h45 à 12h45, David Tsang, salle Jules Verne, OMP, site Belin Resumé: I will discuss the basic structure of Neutron stars, including the Tolman-Oppenheimer-Volkoff equations, the dense matter equation of state, and the properties of the neutron star crust and core. I will then discuss how asteroseismic modes of a neutron star […]
le 20 octobre 2023, 10h45 à 12h45, Katia Ferrière, salle Jules Verne, OMP, site Belin Resumé: Magnetic fields are ubiquitous in the Universe. Most celestial bodies, from planets to stars to galaxies, appear to be magnetized. Even intergalactic space could be threaded by a magnetic field. Cosmic magnetic fields generally play an important role. They […]

le 6 octobre 2023, 10h45 à 12h45, Oliver Berné, salle Jules Verne, OMP, site Belin Resumé: In this seminar, I will present the first scientific results that have been obtained from the JWST mission. After a general presentation of the mission and science results on various topics, I will describe the Early Release Science (ERS) project […]
le 29 septembre 2023, 10h45 à 12h45, Nicolas Laporte, salle Jules Verne, OMP, site Belin Resumé: One of the most intriguing topics in modern extragalactic astronomy is the quest to understand when the first generation of stars and galaxies bathed the Universe in light. This quest for Cosmic Dawn began in the 1950s and has […]
le 22 septembre 2023, 10h45 à 12h45, Angèle Mouinié, salle Jules Verne, OMP, site Belin Resumé:
le 15 septembre 2023, 10h45 à 12h45, Florian Debras, salle Jules Verne, OMP, site Belin Resumé: With more than 5000 exoplanets discovered, we have access to numerous statistics which represent the condition of formation and evolution of planetary systems. One of such statistics is the eccentricity distribution of warm Jupiters: planets around the mass of Jupiter, […]
le 8 septembre 2023, 08h30 à 10h15, Natalie Webb, salle Jules Verne, OMP, site Belin Resumé: Thanks to large surveys such as Gaia, the Sloan Digital Sky Survey (SDSS), GALEX, 2MASS, NVSS, FIRST, XMM-Newton and Chandra, we have catalogued many different stars and galaxies. We have also found some very exotic objects, especially when we observe […]
