Magnetic activity of red giants: Correlation between the amplitude of solar-like oscillations and chromospheric indicators
Previous studies have found that red giants (RGs) in close binary systems undergoing spin-orbit resonance exhibit an enhanced level of magnetic activity with respect to single RGs rotating at the same rate, from measurements of photometric variability, S ph ', and the chromospheric emission S-index, S Ca II. Here, we consider a sample of 4465 RGs
