Tracing the Evolution of Matter from Dying Stars to the Solar System: A Laboratory Astrophysics Journey into Aromatics

Le 28 novembre 2025, Christine Joblin & Hassan Sabbah, 10h45 à 12h45, Salle Jules Verne, OMP, site Belin Summary: With the groundbreaking infrared capabilities of the James Webb Space Telescope, we can now observe the emission from polycyclic aromatic hydrocarbons (PAHs) with unprecedented precision in star- and planet-forming regions. In parallel, sample return missions are […]

Atmospheric physics and observations of giant exoplanets 

Le 14 novembre 2025, Florian Debras, 10h45 à 12h45, Salle Jules Verne, OMP, site Belin Summary: More than 5500 exoplanets have been discovered since 1995, the majority of which having roughly the size and mass of Jupiter as larger planets are easier to detect.In 20 years, our observation techniques have largely improved, and we can obtain reliable constraints […]

Atmospheric ion escape and its role in the evolution of planetary atmospheres

Le 7 novembre 2025, Iannis Dandouras, 10h45 à 12h45, Salle Jules Verne, OMP, site Belin Summary: Understanding the evolution of planetary atmospheres, and particularly the evolution of their composition and eventual habitability, is a major challenge. The evolution of an atmosphere is driven by its interactions with the planetary surface and interior, the influx from […]

Mining big data to find new and rare objects in the Universe

le 21 novembre 2025, Natalie Webb, 10h45 à 12h45, salle Jules Verne, OMP, site Belin Summary: Large surveys such as Gaia, the Sloan Digital Sky Survey (SDSS), GALEX, 2MASS, NVSS, FIRST, XMM-Newton and Chandra, have catalogued many different stars and galaxies. Other more exotic objects can also be found such as black holes, neutron stars […]

Asteroseismology of Neutron Stars

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 […]

Cosmic Magnetic Fields

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 […]

Writing a proposal for Space Based missions

le 13 octobre 2023, 10h45 à 12h45, Sylvestre Maurice, salle Jules Verne, OMP, site Belin Resumé: 

Results from the James Webb Space Telescope

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 […]

The first stars and galaxies : new insights from the James Webb Space Telescope

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 […]
