論文摘要

Interplay between Molecular Clouds and Young Objects in the Rho Ophiuchus

Aashish Gupta (National Central University); Wen-Ping Chen (National Central University)

The ρ Ophiuchus cloud complex, with its proximity (∼138 pc) and a high concentration of gas and stellar population in infancy (1-2 Mys), is a vintage laboratory to study macrophysics of star formation. Here we present the deepest 850-micron JCMT/SCUBA-2 image and most complete catalogue of Young Stellar Objects of the region. Using these datasets, we diagnosed the spatial and kinematic correlation of the young stellar population, at different evolutionary stages classified using SEDs, with respect to the gaseous structures. Among other interesting results, we can see a bound cluster forming in Oph A, simultaneously with star-formation.
