Clustered Star Formation and the Origin of Stellar Masses
Ralph E. Pudritz
Star clusters are ubiquitous in galaxies of all types and at all
stages of their evolution. We also observe them to be forming in a wide
variety of environments, ranging from nearby giant molecular clouds to
the supergiant molecular clouds found in starburst and merging
galaxies. The typical star in our galaxy and probably in others formed
as a member of a star cluster, so star formation is an intrinsically
clustered and not an isolated phenomenon. The greatest challenge
regarding clustered star formation is to understand why stars have a
mass spectrum that appears to be universal. This review examines the
observations and models that have been proposed to explain these
fundamental issues in stellar formation.
