Abstract
In this chapter we describe properties of the nearest star-forming complexes, and physical processes which lead to, and are associated with, star formation. We present basic ideas and recent results, primarily from an observational viewpoint, with emphasis on spectroscopy. We present in §3 properties of dense cores, in §4 the role of turbulent cores in forming star clusters, in §5 evidence for inward motion in dense cores, and in §6 some models of inward motion.
