UM atUM [S03-ep06]: Stellar Magnetic Fields

This week on *AUM science*, Julien Morin, a researcher at the Univers et Particules laboratory in Montpellier (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 learn about aquaponics. The show airs every Wednesday at 6 p.m. on Divergence FM 93.9.

On October 13, Hubert Reeves, one of the pioneers of French astrophysics, passed away. A professor of nuclear physics at the University of Montreal and an advisor to NASA in the early 1960s, he moved to Belgium and then to France in 1965 at the invitation of the CNRS, which offered him a position as research director. In 1971, he published an article with two of his students that revolutionized our understanding of the elements produced during the life cycles of stars. Around the same time, he demonstrated an extraordinary talent for popularizing science, which would later lead him to television appearances—notably the unforgettable *Nuit des étoiles* episodes that left a lasting impression on an entire generation. Even today, Patience in the Azure and *Stardust* remain classics for sky enthusiasts, inspiring many to pursue careers in astronomy.

And perhaps that’s the case with our guest. He is a researcher at the Universe and Particles Laboratory in Montpellier. We had him here in this studio in 2021 to talk about a very young exoplanet discovered thanks to Spirou, a spectropolarimeter and planet hunter developed for the Canada-France-Hawaii Telescope.  We’re joined by him again today to discuss a new paper on the magnetic field of the red dwarf Ad Leonis, published in the journal *Astronomy and Astrophysics*.

In the second half of the program, we continue our tour of the Mediterranean Coastal Environment Station, where we’ll explore the new aquaponics training facility. Gérard Sposito, a project manager in the continuing education department of the aquaculture division, explains how fish can be raised and plants grown within the same system.
