WebNeutron stars form in the death throes of stars with masses of 10–20 M ⊙. Such high-mass stars can form at any time. Theory suggests, though, that they are dominant in the early universe, a few hundred million years after … WebStars are born out of the gravitational collapse of cool, dense molecular clouds. As the cloud collapses, it fragments into smaller regions, which themselves contract to form stellar cores. These protostars rotate faster and increase in temperature as they condense, and are surrounded by a protoplanetary disk out of which planets may later form.
