Toward a Statistical Understanding of Star Formation: the Origin and Evolution of Stars and Disks


Our current understanding of the phases of low mass star formation was built on classifications which could be defined based on in-depth observations of relatively few objects. Similarly, investigations of the role of turbulence and magnetic fields in the regulation of star formation processes rest observationally on relatively few star-forming cores in well-studied regions. Other parameters, such as the timescales of each phase or the presence of extinction thresholds for star formation require observations of ensembles of objects through wide-field imaging. I will present some recent work on specific protostellar objects, such as Barnard 1c, as well early results from a current Spitzer survey which illustrates the approach being taken to address star formation statistically. I will also discuss upcoming far-IR and submillimeter surveys which are critical for assessing the formation rate and lifetimes of starless cores and Class 0 objects. Finally, I will discuss how outstanding questions can be addressed with centimeter/millimeter surveys for dense gas with the EVLA, GBT and ALMA.
