Observations in the UV Band and Problems of Star Formation Studies

Abstract

In this contribution, I consider those aspects of the modern star formation theory, which can be substantiated with observations in the UV band, paying special attention to early stages of molecular cloud formation and initial conditions for the chemical evolution of starless cores. I describe the main results of available diffuse cloud observations in the UV band, as well as prospective directions for future studies with the instrumentation of the World Space Observatory project.
