Stellar formation is the process by which stars are created from interstellar gas and dust within molecular clouds. This process typically begins with the gravitational collapse of a region within a molecular cloud, leading to the formation of a dense core of material. As the core continues to collapse, it heats up and begins to form a protostar, which will eventually evolve into a full-fledged star. During the process of stellar formation, various physical and chemical processes occur, including the accretion of material onto the protostar, the formation of a protoplanetary disk, and the eventual ignition of nuclear fusion within the core of the star. Stellar formation is a complex and dynamic process that can be studied using a variety of observational and theoretical techniques, and it plays a crucial role in shaping the structure and evolution of galaxies.
