Science at UM [S03-ep06]: Stellar magnetic fields
This week on A l’UM la science, Julien Morin, researcher at the Montpellier Universe and Particles Laboratory (LUPM), talks to us about the magnetic field of the star AD Leonis. Our report takes you to the Mediterranean Coastal Environment Station (Smel) in Sète to discover aquaponics. The program is broadcast every Wednesday at 6 p.m. on Divergence FM 93.9.
On October 13, Hubert Reeves, one of the fathers of French astrophysics, joined the stars. A professor of nuclear physics at the University of Montreal and advisor to NASA in the early 1960s, he arrived in Belgium, then France in 1965 at the invitation of the CNRS, which offered him a position as director of research. In 1971, he published an article with two of his students that revolutionized our knowledge of the elements produced during the life of stars. At the same time, he demonstrated a remarkable talent for popularizing science, which would later lead him to television, notably the unforgettable Nuit des étoiles (Night of the Stars) program that left its mark on an entire generation. Even today Patience in the blue and Stardust remain classics for sky lovers and have inspired many a vocation.
And perhaps this is the case for our guest. He is a researcher at the Montpellier Universe and Particles Laboratory. We welcomed him to this studio in 2021 to talk about a newly discovered exoplanet found thanks to Spirou, a spectropolarimeter and planet hunter developed for the Canada-France-Hawaii Telescope. We are meeting him again today to talk about a new publication on the magnetic field of the red dwarf Ad Leonis, published in the journal Astronomy and Astrophysics.

In the second part of the program, we continue our visit to the Mediterranean coastal environment station, where we will discover the new aquaponics training unit. Gérard Sposito, project manager in the continuing education department at the aquaculture center, explains how fish can be farmed and plants grown in the same system.
