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.
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.
All stars are formed from protostars.
On the contrary, "protostar" is the name of an early stage in the development of a star.
Protostars
The clumped spinning masses of hydrogen and dust that eventually become stars are called "molecular clouds" or "stellar nurseries." Within these regions, gravity causes the gas and dust to collapse and condense, leading to the formation of protostars. Over time, as these protostars accumulate more material and heat up, they can ignite nuclear fusion and become fully-fledged stars.
Protostars are the beggining of stars
Clouds of gas will collapse, under certain circumstances, due to their own gravity. These will eventually become stars. This process is described in more detail in the Wikipedia article on "Protostars".
Glowing cloud sections that will eventually become stars are protostars. These protostars are clouds of interstellar gas and dust, which gradually collapse causing a hot dense core to form and evolve into a star.
Clouds of gas and dust, called nebulas and then form into protostars.
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.
Protostars was created in 1971.
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.
