Research Interests

• The formation and evolution of spiral galaxies M31, like the Milky Way, is a nearest spiral galaxy to us. It offers another opportunity that study the formation and evolution of spiral galaxies through individual stars. The metallicity and abundances gradient will be explore based on the large sample of supergiants from LAMOST survey.
• Galactic Archeaology Stellar streams encode enormous amounts of information on the present dynamical state and the formation history of the Milky Way. Searching streams and identifying their origination will enable us to trace the whole history of Galactic disk(s).
• Astroseismology and Spectroscopy data Asteroseismology can provide the fundamental quantities, such as radii and masses, which can be used to obtain information on distances and ages with the complementarity of effective temperature and chemical compositions obtained from spectroscopy analysis.
• Chemical Tagging Chemical tagging is a powerful technique to reconstruct dissolved star clusters and identify tidal debris from accreted galaxies through elemental abundances. It can help us to study the radial mixing or migration process of the Galactic disk(s).

Research grant
