Color–absolute magnitude diagram for the sample of AFGKM-type stars, where points are color coded according to number density on a logarithmic scale. The two sequences emerging from the lower right and upper right regions, where BP − RP exceeds 1.5 mag, correspond to the M-type stars compiled by B. Du et al. (2024).
