Location of the search sample (GKM-type main-sequence stars, Teff < 6000 K, log[g/(cm s−2)] > 4.0) on the Hertzsprung-Russell diagram. The stellar parameters corresponding to the grey squares are obtained from the LAMOST-MRS parameter catalogue in the LAMOST DR8. The green crosses represent the sample for this study, and their parameters come from the LAMOST-MRS parameter catalogue in the LAMOST DR8 and DR9 v0. The red solid circles show the locations of the host stars for the three stellar CME candidates.
