PublicaciónMagnetic and Rotational Evolution of ρ CrB from Asteroseismology with TESS
During the first half of main-sequence lifetimes, the evolution of rotation and magnetic activity in solar-type stars appears to be strongly coupled. Recent...

PublicaciónMapping magnetic activity indicators across the M dwarf domain
Stellar activity poses one of the main obstacles for the detection and characterisation of exoplanets around cool stars, as it can induce radial velocity (RV)...

PublicaciónMapping stellar activity indicators across the M dwarf domain
Despite stellar magnetic activity being present in most cool stars, its effects on spectroscopic observations are still not well understood. Several activity...
