How does the protostar stage of a stars life cycle compare with the main sequence stage?
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.

How does the protostar stage of a star's life cycle compare with the main-sequence stage?
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
Is the sun a protostar?
No, the sun is not a protostar. It is a mature star that is in the main sequence phase of its life cycle, where it fuses hydrogen into helium in its core. A protostar is a young star that is still in the process of accumulating mass and contracting before it begins hydrogen fusion in its core.
Which stage comes first in the life cycle of a high-mass star?
The stage that comes first in the life cycle of a high-mass star is the main sequence stage. During this stage, the star fuses hydrogen into helium in its core, maintaining a balance between radiation pressure and gravity.
What stage comes after nebula in the star stage?
The stage that comes after the nebula in the star's life cycle is the protostar stage. During this stage, gravity causes the gas and dust within the nebula to clump together and heat up, eventually forming a dense, hot core. This marks the beginning of nuclear fusion within the protostar.
The third stage in the life cycle of a star?
The third stage in the life cycle of a star is the main sequence stage, where a star fuses hydrogen into helium in its core. During this stage, stars like our Sun are stable and shine steadily due to the balance between gravitational forces pulling inward and nuclear fusion pushing outward. This stage can last for billions of years, depending on the mass of the star.
What come after a nebula?
After a nebula, the next stage in the life cycle of a star is usually a protostar, where gravity causes the gas and dust within the nebula to begin collapsing and forming a dense core. Following this stage, the protostar may evolve into a main sequence star, where nuclear fusion begins in its core and it enters a stable period of energy production.
What type of fuel does a protostar burn?
A protostar does not burn fuel as it is still taking part in nuclear fusion. It is, however, preparing to become a main sequence star, and will then burn mostly hydrogen at that stage.
The earliest stage of a stars life is called a?
A Protostar.
What are the stages of the sun's life cycle?
The sun's life cycle includes the stages of formation, main-sequence, red giant, and white dwarf. It is currently in the main-sequence stage, where it fuses hydrogen into helium in its core. Eventually, it will expand into a red giant before shedding its outer layers and becoming a white dwarf.
What is a stable stage in the life cycle of a star?
The "main sequence".
What life cycle stage is wolf 359 in?
main sequence
Are protostar a star?
A protostar is more like a stage previous to a star - before it ignites.
