PublicationGiant white-light flares on fully convective stars occur at high latitudes
In a systematic analysis of fully convective stars observed with TESS, we detected four stars that displayed giant flares that were...

PublicationIUE MG II doublet observations in F and G main sequence stars
Mg II resonance lines at 2800 A were studied in the spectra of F and G main sequence stars, observed with the IUE satellite in high resolution mode. Correlation...

PublicationLithium and rotation in the Hyades late F and G stars
Selecting stars with previously measured or estimated rotational periods we have measured equivalent widths of the Li doublet (6708 A) in 8 stars of the Hyades...

PublicationLithium in T Tauri stars
The lithium abundance in 26 T Tauri stars is derived using data taken at the Isaac Newton Telescope and data from literature. The aim is to understand the...

PublicationMagnetic Activity Evolution of Solar-like Stars. I. S <SUB>ph</SUB>-Age Relation Derived from Kepler Observations
The ages of solar-like stars have been at the center of many studies such as exoplanet characterization or Galactic-archeology. While ages are usually computed...

PublicationMagnetic 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...
