Measuring the magnetic fields in the chromospheres of low-mass stars
Tianqi Cang, Pascal Petit, Jean-François Donati +11
Magnetic fields in the upper atmospheres of solar-like stars are believed to provide an enormous amount of energy to power the hot coronae and drive large-scale eruptions that coul…
Solar and Stellar Activity
S. Bellotti, J. Morin
This chapter provides an overview of the magnetic activity of the Sun and stars, discussing its underlying physical origin, manifestations, and fundamental role in exoplanet studie…
The magnetic and spin-down properties of slowly rotating fully convective M dwarfs
Victor See, Louis Amard, Stefano Bellotti +19
The evolution of the magnetism, winds and rotation of low-mass stars are all linked. One of the most common ways to probe the magnetic properties of low-mass stars is with the Zeem…
Evolving magnetic lives of Sun-like stars. I. Characterisation of the large-scale magnetic field with Zeeman-Doppler imaging
S. Bellotti, T. Lueftinger, S. Boro Saikia +6
Planets orbiting young, solar-type stars are embedded in a more energetic environment than that of the solar neighbourhood. They experience harsher conditions due to enhanced stell…
Location and energy of electrons producing the radio bursts from AD Leo observed by FAST in December 2021
Philippe Zarka, Corentin K. Louis, Jiale Zhang +3
In a recent paper, we presented circularly polarized radio bursts detected by the radio telescope FAST from the flare star AD Leo on December 2-3, 2021, which were attributed to th…
