Primordial Evolution of Dense Cores: Learning from Observations
and Simulations

We present results on our studies of the early stages of evolution of dense cores in a Giant Molecular Cloud from both the observational and the computational point of view. On one hand, our high resolution near-IR extinction maps of a collection of little evolved dense cores in the Pipe Nebula refresh our understanding of their characteristics, from the scale of their internal structure to the global perspective of the whole cloud. On the other hand, our exploration of the characteristics of dense cores in a simulated filamentary cloud, as they evolve toward condensation and gravitational collapse, contribute to the understanding of the global properties of dense cores in their early stages. | |
Caption: Extinction map of the Barnard 59 region at a spatial resolution of 20''. The map was constructed with a combination of ground based near-IR imaging data from ESO-NTT/VLT and the 2MASS survey and space based mid-infrared IRAC images from the Spitzer Telescope. The map reveals the complex structure of filaments and peripheral cores and resolves for the first time the internal structure of the central, active cluster forming core. | |
