| Research Abstract |
We studied the origin of two modes of star formation : "isolated" vs. "clustered" ; the former mostly represents low-mass star formation and the latter high-mass. In this context, we searched for extremely young protostar(s) as well as cluster of such (proto)stars over a wide range of stellar masses, and investigated physical properties of their natal molecular gas, focusing on accretion onto central star(s).
