論文摘要

Evolution of the Stellar Family Structure

[ Oral ]

Wen-Ping Chen 陳文屏 (NCU)

Stars are formed in groups out of dense molecular clouds. Most these stellar aggregates are dispersed as long as placental gas and dust is cleared, and only a minor fraction remain gravitationally bound and seen today as star clusters. I will report on the efforts by my group to diagnose the cluster dynamical evolution, from initial morphology at birth, to mass segregation via internal relaxation, to stellar evaporation that eventually leads to cluster disintegration, with then-members becoming the Galactic field stars. I will outline a few outstanding issues in the study of star clusters in general.
