- A protostar is a stage in the formation of a star where a dense cloud of gas and dust begins to collapse under its own gravity. This collapse triggers the process of nuclear fusion, which eventually leads to the birth of a new star.

A protostar is a very young star that is still gathering mass from its parent molecular cloud. It is the earliest phase in the process of stellar evolution. [1] For a low-mass star (i.e. that of the Sun or lower), it lasts about 500,000 years. [2]
Apr 9, 2024 · Protostars become stars when nuclear fusion begins in their cores. This process involves the fusion of hydrogen atoms into helium, releasing energy in the form of light and heat. Once fusion ignites, the protostar starts shining brightly and becomes a main sequence star.
Nov 21, 2023 · A protostar is a young star that has not yet depleted its surrounding molecular gas through gravitational contraction. Additionally, a protostar's core has not yet...
Apr 12, 2024 · What is a Protostar? A protostar is a young star that is still in the process of forming. It is the stage in a star’s life cycle before it becomes a fully-fledged star, like our Sun. Protostars are typically found in dense regions of interstellar gas and dust, where gravity causes these materials to clump together and form a dense core.
Apr 11, 2022 · During the time a dense core is contracting to become a true star, but before the fusion of protons to produce helium begins, we call the object a protostar. Figure \(\PageIndex{7}\) Formation of a Star.
Aug 30, 2004 · Protostars. The image below shows a very young protostar, still deeply embedded in its dust cloud. The star itself is the bright red spot near the base of the dark region. The bright spots above the star and strange spikes are artifacts in the image.
