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 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.
What is the time taken by a to orbit the sun is a?
more than a million years
What is the future tense of shone?
Shone, or more commonly, shined, is the future tense of shine.

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 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 time references best fits the concept of geologic time a dozen years a hundred years a thousand years a million or more years?
a million or more years

When was More Shine created?
More Shine was created on 2005-09-27.
Would geologic time be more like 12 years 100 years 1000 years or 1 million years?
Geologic time is very long, so a million or more years is the best choice.
How old is the Nile River?
As old as history itself, at least a few million years.
What best fits the concept of geologic time a dozen years a thousand years a hundred years or a million or more years?
A million or more years best fits the concept of geologic time. Geologic time spans millions to billions of years and is used to describe the immense length of time over which Earth's processes have occurred, such as the formation of mountains, evolution of species, and movement of continents.
How long can a star shine for?
Small dim stars can shine for a trillion years or more. The more massive a star is, the BRIGHTER it is, and the faster it burns out. Our Sun is perhaps just a bit larger than average, but not by a whole lot; our Sun has already burned for 4.5 billion years or so, and we can expect as much more. But it won't be the Sun as we know it; in 3 billion years or a little more, it will expand into a red giant. Very large stars like Betelgeuse are already quite old and about to die - spectacularly! - at fairly early ages. (Some time within the next 100,000 years) And yet, Betelgeuse is only about 100 million years old!
