Protostellar research focuses on the study of the earliest stages of star formation, when a dense core of gas and dust collapses under its own gravity to form a protostar. Protostars are not yet undergoing nuclear fusion, but are still accumulating mass and growing in size. Researchers in this field aim to understand the physical processes that govern the formation and evolution of protostars, as well as the role they play in shaping the formation of planetary systems. Observational studies using telescopes like the Atacama Large Millimeter Array (ALMA) and theoretical modeling are both crucial tools in protostellar research.
