A protostar is a massive object that forms from the contraction of gas from a giant molecular cloud. This protostellar phase is the early stage of star formation. For a protostar with the mass of the Sun it will last about 100,000 years. It starts with a core of increased density in a molecular cloud and ends with the formation of a T Tauri star, which then develops into a main sequence star. This is heralded by the T Tauri wind, a type of super solar wind that marks the change from the star accreting mass into radiating energy. A T Tauri star is similar to those of main sequence stars of the same mass, but they're significantly more luminous because their radii are larger. See related links for more information.
What else can I help you with?
What is the temperature of a protostar?
the color of the protostar is red
Will a protostar form near the end of a star's life cycle?
No, a protostar is basically the BEGINNING of a star's life cycle.
How long does a protostar live?
A protostar will live as long as 100,000 years. After material stops falling on the protostar it will enter then T Tauri star phase.
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.
What two forces are within a protostar?
Gravitational force - which pulls matter towards the center of the protostar and is responsible for its contraction. Thermal pressure - which is generated by the heat and pressure within the protostar's core and pushes outward to counteract the gravitational force.
What are all the gases in a protostar?
Mostly hydrogen (with some helium, deuterium, and lithium). Other elements (all other elements) are added as the date of formation of the protostar comes closer to the current date.
The earliest stage of a stars life is called a?
A Protostar.
What is the life span of protostar?
A protostar takes about 100,000 years to reach the main sequence.
Are protostar a star?
A protostar is more like a stage previous to a star - before it ignites.
Do prostars become stars?
The term is "protostar", not "prostar". Yes. A protostar is an early stage of a star.
Was the Sun a protostar about a million years ago?
No. The sun was a protostar about 4.6 billion years ago.
What is the temperature of a protostar?
the color of the protostar is red
Who the heck thinks the question what is a protostar means what does a protostar look like?
Apparently someone not paying ATTENTION.
Who named the protostar and why?
No one. It comes from the Greek - proto - meaning first. So first star - a protostar.
What is a binary protostar?
"Binary" means there are two stars. And "protostar" means the stars are in an early, or preliminary, stage.
Who went to a protostar?
No one
What slow down the contracting of a star forming cloud when it makes a protostar?
trapping of thermal energy inside the protostar
