Answer:
Step-by-step explanation:
Here's what the gas is doing in this context:
Accretion: The gas is falling inward toward the protostar due to gravitational attraction. As it falls, it gains kinetic energy and heats up, forming a rotating accretion disk around the protostar.
Heat and Pressure: As the gas accumulates in the vicinity of the protostar, it becomes increasingly compressed and heated. The increasing temperature and pressure at the core of the protostar trigger nuclear fusion reactions, which are the processes that power stars.
Formation of a Star: The gas continues to accrete onto the protostar until a point is reached where the internal temperature and pressure are sufficient to sustain nuclear fusion reactions in its core. At this stage, the protostar becomes a full-fledged star, primarily fueled by hydrogen fusion.
Outflow and Jets: During the protostellar phase, there can also be outflows and jets of gas and material emanating from the protostar's poles. These outflows can carry away excess angular momentum and help regulate the star formation process.
