Why does the temperature of a protostar increase?
The temperature of a protostar increases due to gravitational contraction. As the protostar contracts, potential energy is converted into kinetic energy, causing the particles to move faster and collide more frequently, resulting in an increase in temperature. This process eventually leads to the ignition of nuclear fusion and the star's main sequence phase.
When does a protostar become a star?
A protostar becomes a star when nuclear fusion begins in its core, primarily converting hydrogen into helium. This process generates the energy that allows the star to emit light and heat, officially making it a star.
What species absorbs photons in a protostar's outer layers?
In a protostar's outer layers, hydrogen atoms absorb photons. This process triggers nuclear fusion reactions that release energy and contribute to the protostar's growth and development into a stable star.
Can a protostar shine for more than 1 million years?
No, a protostar typically evolves into a main sequence star within a few million years. The early stages of a protostar involve gravitational collapse and the conversion of gravitational potential energy into heat and light. Once nuclear fusion ignites in the core, the star enters the main sequence phase and can shine for billions of years.
Why does heat build up more rapidly in a massive protostar than in a less massive one?
Heat builds up more rapidly in a massive protostar because more mass leads to greater gravitational pressure, resulting in higher temperatures and higher fusion rates in its core. This high fusion rate produces more energy and leads to a faster increase in temperature in the massive protostar compared to a less massive one.
How does a nebula form into a prostar?
The basic idea is that it is pulled together by its own gravity. For more details, check the Wikipedia article on "protostar".

Are protostar a star?
A protostar is more like a stage previous to a star - before it ignites.
Why does temperature increase more rapidly in a more massive protostar than in a less masive protostar?
because the jews said so
What is happening to the star of a protostar?
A protostar is a star that is just beginning to form out of a stellar nebular (under gravity). The core of the gravitational collapse is getting more and more massive and is heating up as a result of the gravimetric contraction but has not yet reached the point where nucleosynthesis has begun in its core. It is when this happens that it becomes a star.
What is the first step of stellar evolution?
The formation of a protostar from a nebula. As the protostar forms, it accretes more mass from the cloud and spins. As it gains more mass, it eventually becomes massive enough to ignite the core and become a star. The protostar is the first step in the evolution of any star.

What is a contracting cloud of gas and dust with enough mass to form a star?
It is called a protostar. As the protostar gathers more mass and becomes denser, nuclear fusion reactions are triggered at its core, leading to the formation of a new star.

No, a protostar typically evolves into a main sequence star within a few million years. The early stages of a protostar involve gravitational collapse and the conversion of gravitational potential energy into heat and light.

What happens when matter cools?
One thing that happens is that the molecules in the matter lose energy and momentum and slow down, therefore the matter becomes more compact.
What does 'A matter of cause' mean?
'as a matter of course'if something happens as a matter of course, it happens without people thinking about whether they want it or not.The question itself has an error; the idiom is, as correctly pointed out above, as a matter of course.
What happens is energy is taken away from matter?
When thermal energy is taken away from matter particles move more slowly. When thermal energy is added to matter particles move faster.
