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 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.
Gravitational force is what causes protostars to form. Gravity pulls together gas and dust in a molecular cloud, causing it to clump and collapse, eventually leading to the formation of a protostar.
The Wikipedia article mentions CARMA-7 and HBC-1 as examples.
Protostars are difficult to observe because they are surrounded by dense clouds of gas and dust, which block their visible light from reaching us. Additionally, protostars are still forming and are often embedded within their natal clouds, making it challenging to distinguish them from the surrounding material. Their emission is often in the infrared, which can be absorbed by Earth's atmosphere.
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.
Protostars was created in 1971.
Protostars has 271 pages.
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
small nebulae that fluctuate in brightness
Gravitational force is what causes protostars to form. Gravity pulls together gas and dust in a molecular cloud, causing it to clump and collapse, eventually leading to the formation of a protostar.
Clouds of gas and dust, called nebulas and then form into protostars.
If you can see it, its a star. Protostars radiate only in the infrared.
On the contrary, "protostar" is the name of an early stage in the development of a star.
