Important forward step in colour-magnitude diagram study: successful simple stellar population model for interpreting CMDs of LMC star clusters
Prof. Dr. Zhongmu LI
Zhongmu Li's group brought a new model for interpreting CMDs of LMC. Most observational results such as broad or multiple turn-offs, broad or dual red clumps, blue stragglers, red stragglers, and wide main sequence can be successfully explained by bianry star simple stellar populations (bsSSPs) including both binary evolution and stellar rotation. This is the only SSP model that can explain most observations by now. The result will be published by Astrophysical Journal Letters.
