Here is a summary of the projects I am working on.

Each work tried to answer one or more specific questions, click the following links to see more detailed explanation.

Population of stellar rotation rates in star clusters

• Whether stellar rotation rates is the reason for extended main-sequence turnoff found in intermediate-age clusters?

• Does split MS originates from stellar rotation dichotomy? If true, what causes the rotation distribution?

• Can stellar rotation explain every clusters? Is there any contribution from other mechanism?

• Is the rotation rates in star clusters regulated by the same mechanism? Whether we can distinguish different formation scenario for the observed rotation distribution?

Blue straggler stars in Magellanic Clouds clusters

• What's the origin of blue straggler stars in Magellanic Clouds clusters? Formed from primordial binaries or dynamical interaction?

• Can we use the radial distribution of blue straggler stars as dynamical clocks in Magellanic Clouds clusters?

Properties of contact binaries

• How to derive physical parameters for large population of contact binaries with only photometric observation? Is there any difference between various subtypes?

Planetary nebulae in globular clusters

• Is there any planetary nebulae in globular clusters in the Virgo cluster? If so, what can we learn from that?

Mass function of young massive clusters

• Is the initial cluster mass function universal?
