Li-rich giant stars under scrutiny: binarity, magnetic activity, and the evolutionary status after Gaia DR2
We present a study of the evolutionary state of a few lithium-rich giant stars based on the Gaia Data Release 2 (DR2) parallaxes and photometry. We also investigate the chromospheric activity, the presence of a surface magnetic field, and the radial velocity for our sample stars. We analysed both ar...
