Cloud Morphology Also Shapes the Clusters

Feedback from massive stars is thought to play an important role in the evolution of molecular clouds. Although the effect of stellar feedback in simulated giant molecular clouds (GMCs) has been studied in detail, the initial conditions of these simulations lacked the complexity of observed clouds, or the effect of the feedback was studied in full-scale galactic models that did not properly resolve sub-pc physics. We present the first simulations of two clouds (one gravitationally bound collapsing cloud and one unbound cloud disrupted by galactic shear) which are extracted from large scale galactic models and are re-simulated at a spatial resolution of ~ 0.01 pc, with a mass resolution of 0.5 Msun, and including feedback from winds, supernovae (SNe). We find that the morphology of the cloud plays also an important role in the creating of the stellar clusters. We observe the impact of the SNe, as our model is now self-consistent, although its effect on the cloud is minor compared to winds. | |
