Notes. Block 1: Red giants from Gaulme et al. (2020). Inactive stars present no evidence for rotational modulation in the light curve, while stars with low-S/N spots and clear spots exhibit rotational modulation, and have a measurement of their rotation period. Block 2: Red giants from Gaulme et al. (2020) that are identified as binaries by Gaia DR3. Wide binaries have an orbital period P_orb > 150 days, while close binaries have P_orb ≤ 150 days. Non-oscillating stars are in a close binary system that is tidally locked or in spin-orbit resonance, with clear rotational modulation and a measured rotation period. Block 3: Post-mass-transfer red giant candidates of Deheuvels et al. (2022) and Rui & Fuller (2021). The control sample of Deheuvels et al. (2022) is composed of RGB stars with no evidence for a mass gain, i.e. low-mass red giants with a degenerate core and intermediate-mass red giants with a nondegenerate core.
