Formation of Population II Stars

Publications of the Astronomical Society of Japan, 1975
Abstract Thermal and dynamical properties of gas clouds of mass between 1 M◉ and 106  M◉ with a fractional mass of heavy elements Z=10−3 to Z=10−5 are investigated by comparing the time scales of cooling, heating, expansion, and contraction for two cases with and without grains.
