Protostar - Wikipedia
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]
Protostar – Definition & Detailed Explanation - Sentinel Mission
What is a Protostar? 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.
What is a Protostar? (with pictures) - AllTheScience
A protostar is a young star which is in the early stages of formation, before it reaches the main sequence stage. This stage of star formation can last 100,000 years or more, depending on the size of the star.
Protostar - Las Cumbres Observatory
A protostar becomes a main sequence star when its core temperature exceeds 10 million K. This is the temperature needed for hydrogen fusion to operate efficiently. The length of time all of this takes depends on the mass of the star.
Protostars - Harvard University
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.
Glossary term: Protostar
Description: A protostar is an early stage in the star formation process. It is a large mass of gas and dust formed as a result of the contraction of a giant molecular cloud in the interstellar medium. As the cloud collapses, gravitational energy is converted into heat, warming the still-forming protostar.
Protostar - Simple English Wikipedia, the free encyclopedia
Protostar is an early stage in the evolution of a star that usually grows to the point of beginning nuclear fusion and becoming a star by gathering mass. [1] It is made of a contracting cloud of cold and dark interstellar medium (mostly hydrogen gas).
Protostar Formation - Definition & Detailed Explanation - Astronomical ...
A protostar is a young star that is still in the process of forming. It is the earliest stage in the life cycle of a star, before it begins nuclear fusion in its core. Protostars are typically found within dense molecular clouds, where gravity causes the gas and dust to collapse in on itself, forming a dense core that will eventually become a star.
What is A Protostar – Mass Formed Because of Contraction of Gas
Because of the gravitational attraction that the molecules have, the nebula can unite into a denser, tightly packed object called a protostar through the process of accretion. The cloud becomes so dense that visible light inside it is blocked and cannot be seen.
Protostar – Definition & Detailed Explanation - Sentinel Mission
A protostar is a young star that is still in the process of forming. It is the earliest stage in the life cycle of a star, before it begins nuclear fusion in its core and starts shining brightly. Protostars are typically surrounded by a dense cloud of gas and dust, which is gradually pulled in by the star’s gravity as it grows in size and mass. II.
