Young Star Clusters

A major study of the molecular gas surrounding young star clusters is underway. We are using the Columbia University 1.2–m millimeter-wave telescope to observe emission from the J=1→0 rotation transition of 12CO in the vicinities of 128 open star clusters. The survey region around each cluster is at least 10 cluster diameters in size, typically ≳ 5 square degrees. Sensitivity is sufficient to detect lines as weak as 1 K over a range in velocity ± 83 km/s centered on the cluster velocity and with a velocity resolution of 0.65 km/s. Clusters in this sample have well-determined distances ranging from 1 to 5 kpc, and ages ≳ 100 million years (Myr).

Young Star Clusters

ABSTRACT More and more observations indicate that young star clusters could retain imprints of their formation process. In particular, the degree of substructuring and rotation are possibly the direct result of the collapse of the parent molecular cloud from which these systems form. Such properties can, in principle, be washed-out, but they are also expected to have an impact on the relaxation of these systems. We ran and analysed a set of 10 hydrodynamical simulations of the formation of embedded star clusters through the collapse of turbulent massive molecular clouds. We systematically studied the fractality of our star clusters, showing that they are all extremely substructured (fractal dimension D = 1.0–1.8). We also found that fractality is slowly reduced, with time, on small scales, while it persists on large scales on longer time-scales. Signatures of rotation are found in different simulations at every time of the evolution, even for slightly supervirial substructures, proving that the parent molecular gas transfers part of its angular momentum to the new stellar systems.

AbstractHere, we present a theoretical model for the global evolution of isolated giant molecular clouds. Accounting for the amount of mass, momentum, and energy supplied by accretion and star formation feedback, we are able to follow the growth, evolution, and dispersal of individual GMCs. We compare our models to observations of GMCs and associated young star clusters in the Large Magellanic Cloud and find good agreement between our model clouds and the observed relationship between Hii regions, young star clusters, and GMCs.
