a. the protostar stage is very short.
b. they are surrounded by cocoons of gas and dust.
c. they radiate mainly in the infrared.
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.
Low temperatures are necessary for dense cores to form and contract into protostars because they promote gravitational collapse. When temperatures are lower, gas molecules move more slowly, allowing gravity to overcome thermal pressure and compress the core. This compression leads to higher densities and temperatures, ultimately initiating nuclear fusion and forming a protostar.
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.
It is relativley rare to observe a solar eclipse because the sun's light is blocked by the moon
Protostars was created in 1971.
Scientists do not observe Mercury as often because it is difficult to do so.
Protostars has 271 pages.
All stars are formed from protostars.
The ISBN of Protostars is 0-345-02393-5.

Pluto is difficult to observe from Earth because it is about 3.66 billion miles away, and only appears as a faint point of light.

Protostars are the beggining of stars
Low temperatures are necessary for dense cores to form and contract into protostars because they promote gravitational collapse. When temperatures are lower, gas molecules move more slowly, allowing gravity to overcome thermal pressure and compress the core. This compression leads to higher densities and temperatures, ultimately initiating nuclear fusion and forming a protostar.
