Theoretical models of star formation

Theoretical models of star formation describe how stars develop from clouds of gas and dust in space. Initially, gravity pulls materials together, forming a dense core. As the core contracts, it heats up and spins faster, creating a protostar. When temperatures reach millions of degrees, nuclear fusion begins, converting hydrogen into helium and releasing energy. This process counteracts gravity, stabilizing the star. The resulting energy output allows the star to shine. There are various models that detail these stages, influenced by factors like cloud density, temperature, and magnetic fields, which help astronomers understand the diverse environments where stars form.
