Diagnosing Evolution of Star Clusters and Their Dynamical Disintegration(3/3)

Project Details

Description

We propose to study the assembly and disassembly of star clusters. Stars are formed in groups out of molecular cloud. Those that survive the internal dynamics plus external perturbation, and remain gravitationally bound, become the star clusters we see today. We will (1) investigate the interplay between the youngest, embedded stellar systems and the molecular gas and dust to trace possible triggered formation of next-generation stars, (2) detect JCMT/SCUBA-2 submillimeter brightness outburst using due to sporadic accretion to diagnose how protostars gain their mass, (3) correlate stars, and in some cases substellar objects, at different evolutionary stages with warm dust clouds, including stellar magnetic activity, (4) derive detailed parameters (age, distance, shape, size, membership, mass function, dynamical status) of nearby star clusters of different ages and at different Galactic locations to quantify the key mechanism leading to disintegration of star clusters.
