Title: Star Formation in Context

Abstract: Stars of low mass can form in nearby, low mass cores, either isolated or as parts of large clouds. As part of this process, disks form around the young stars, providing the site for planet formation. A combination of techniques have been brought to bear on understanding this process. Data from an impressive array of new instruments, including the Spitzer Space Telescope, are revolutionizing this field. Theoretical models can be tested at a new level of detail using self-consistent calculations to translate the models into observables. The formation of massive stars in clustered environments is less understood and inherently more complex. Recent theoretical and observational advances promise insights into massive star formation, which in turn is needed for understanding galaxy formation and evolution. Studies of dust and molecules at high redshift suggest that conditions in some extreme starbursts are similar to those in the dense cores of molecular clouds in our Galaxy.
