In🇬🇧: We measured for the very first time magnetic fields in cores of stars. It shows how powerful is asteroseismology! Read here our article "Magnetic fields of 30 to 100 kG in the cores of red giant stars" published in nature: rdcu.be/cWXAb

Exchange day! Our secondary mirror is replacing MegaCam at the top of the telescope. SPIRou is heading to it's home at the bottom (Cassegrain) of the telescope for its upcoming run.

Boiling coffee with a moka. This is a movie made with neutron images that shows the coffe making process. The movie was made by A. Kaestner at the cold neutron imaging beam line ICON at the Paul Scherrer Institute [full video: buff.ly/2KDuOT4]

Want to know how we can study the magnetic fields of cool stars with our new tool ZeeTurbo? Check out our paper, accepted for publication in MNRAS, and already available on ArXiv: arxiv.org/abs/2303.11241

It's M dwarf time! Eh, paper time! Using ZeeTurbo, I've carried out an analysis of 44 M dwarfs to study their small-scale magnetic fields ! Check out the publication here: ui.adsabs.harvard.edu/abs/2023MNRAS.…

Our Cool Stars 22 splinter session on magnetic fields in the Sun and stars is accepting contributions (deadline March 12) ! Visit our webpage: sites.google.com/cfa.harvard.ed…

M dwarfs are not the only interesting stars out there. Some are big, and rotate so fast they break apart ! Checkout our new paper on NGC 330, accepted for publication in ApJ ! ui.adsabs.harvard.edu/abs/2024arXiv2…

Were you wondering where to read on our latest spectroscopic investigation of the young LMC clusters NGC 1856 and NGC 1953? Well it is now on arxiv, and accepted for publication in ApJ ! arxiv.org/abs/2508.02599

Very happy to share that our latest paper on the small-scale magnetic field of M dwarfs was accepted for publication in A&A and is now available on arXiv ! ui.adsabs.harvard.edu/abs/2025arXiv2… Stay tuned for more at paulcristofari.github.io
