Molecular Clouds & Gravitational Collapse: Observation, Measurement & Evidence

Stars form inside the coldest, densest parts of molecular clouds, enormous complexes made mostly of molecular hydrogen with helium, dust, and trace molecules. Cloud-collapse physics determines where stars form, how efficiently a cloud converts gas into stars, and why stars commonly form in groups.

supported

A dense core can become gravitationally unstable when its mass and density exceed the support available from internal motions and temperature.
