What is the dominant factor in the life of a star?

What is a dominant factor in the life of a star?

From birth to death, the internal pressure of a star created by its own weight is the most dominant factor in the star’s life.

What is the main factor that determines what will happen to a star after it consumes?

About 75% of the mass of the star is ejected into space in the supernova. The fate of the left-over core depends on its mass. If the left-over core is about 1.4 to 5 times the mass of our Sun, it will collapse into a neutron star. If the core is larger, it will collapse into a black hole.

Do stars spend most of their lifespan as Giants?

Stars spend most of their life span as giants. The final stage in the evolution of a star like our Sun is a neutron star.

What is a main sequence star quizlet?

Main sequence stars are stars that are fusing hydrogen atoms to form helium atoms in their cores.

Which stars become neutron stars?

Any main-sequence star with an initial mass of above 8 times the mass of the sun (8 M _☉) has the potential to produce a neutron star. As the star evolves away from the main sequence, subsequent nuclear burning produces an iron-rich core.

What is the life cycle of a star?

Massive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula. All stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant.

At which stage does a star spend most of it’s life?

main sequence phase

A star will enjoy most of its life in the main sequence phase. At this point nuclear fusion is turning hydrogen into helium. The star is only stable because the light pressure of this energy balances out the star’s gravitational collapse.

What is the first stage of a star life?

protostar

The gas in the nebula begins to glow. This is the first step in the life cycle of a star. It is called a protostar.

What is the next stage in a star’s life after the main sequence phase?

Explanation: After the main sequence stage in which a Star burn it’s Hydrogen into Helium, the Star rearranges it self expanding it’s outer layers and shrinking its core becoming a Red-Giant.

Of course, we’re talking about stars here, and the way they’re born, live and die is completely different from any life form we are familiar with.
