Low-metallicity star formation

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

We study the evolution of low-metallicity star-forming clouds up to the formation of protostars by way of radiation hydrodynamics with spherical symmetry. From obtained thermal evolution, we discuss their fragmentation mass scales. From the structure of the envelope at the time of protostar formation, we derive the protostellar accretion rate and calculate the evolution of protostars in the main accretion phase. Finally, we evaluate the upper limit on the stellar mass by the stellar feedback.
