All stars are formed from protostars.
Protostars
Not all protostars become true stars. Some protostars may not have enough mass to sustain nuclear fusion in their cores and never become true stars, instead becoming failed stars known as brown dwarfs.
Protostars are the beggining of stars
1.Nebula ( plural for nebulae) are the birth place of stars. 2. If a critical temperature in the core of a protostar is not reached, it ends up a brown dwarf. 3. Stars begin their lives inside molecular clouds.
Not all protostars become stars; some may fail to accumulate enough mass to ignite nuclear fusion in their cores. Factors such as insufficient material, environmental influences, or interactions with nearby stars can prevent a protostar from reaching the necessary conditions for star formation. Additionally, protostars can also be ejected from their forming regions before they fully develop. Thus, while many protostars do evolve into stars, the outcome depends on various conditions and processes in their formation environment.
Clouds of gas and dust, called nebulas and then form into protostars.
Usually blue.
On the contrary, "protostar" is the name of an early stage in the development of a star.
Because when they are newly formed, they are very hot.
Other stars did the stars. This is true in tabloids as well as in astronomy. The birth of stars is usually preceded by the death of nearby stars. Stars going nova cause compression waves in the interstellar medium, causing pockets of gas to reach critical density. These pockets then collapse in on themselves creating protostars. Protostars contract until they reach critical density, and hydrogen in their cores start to fuse. A star is born.
Stars are formed from clouds of dust and gas known as nebulae. Under the influence of gravity, these clouds collapse and condense, leading to the formation of protostars. As the protostar continues to gather mass and heat up, nuclear fusion ignites in its core, eventually resulting in the birth of a new star.
The prefix "proto-" typically means "first" or "primary," indicating that a protostar is an early stage in the formation of a star. This suggests that protostars are the initial phase in stellar development, where matter begins to clump together and heat up before eventually becoming a fully formed star. The use of "proto" highlights the evolutionary process that stars undergo from formation to maturity.
