Over the last decades, M dwarfs have attracted increasing attention and were identified as targets of choice for the hunt of exoplanets located in the habitable zone of their host star, and for the study of magnetic fields in cool stars. Nonetheless,

Convective cores are the hydrogen reservoirs of main-sequence stars that are more massive than around 1.2 solar masses. Therefore, their sizes strongly impact the stellar evolution. However, several physical processes, which remain poorly understood

Asteroseismology has revolutionised our understanding of stellar interiors, through the observations of oscillations on the surface of stars. In solar-like oscillators, which exhibit a convective envelope, the turbulent motions caused by convection h

Asteroseismology consists in probing stellar interiors through the detection of seismic waves. Red giants are evolved low-mass stars that have exhausted hydrogen in their core. These stars are solar-type pulsators presenting mixed modes that allow us
