What are the 5 stages of a massive star?
All stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant.
- Giant Gas Cloud. A star originates from a large cloud of gas.
- Protostar.
- T-Tauri Phase.
- Main Sequence.
- Red Giant.
- The Fusion of Heavier Elements.
- Supernovae and Planetary Nebulae.
What is the last stage of a massive star?
The final fate of a very massive star, whether it explodes as core collapse supernova, as pair instability supernova, as black-hole accretiondriven supernova, as gamma-ray burst, or just collapses to a black hole, depends on how much mass the star has left when it reached the end of its evolution.
What will be the very last stage of the sun’s life as a star?
All stars die, and eventually — in about 5 billion years — our sun will, too. Once its supply of hydrogen is exhausted, the final, dramatic stages of its life will unfold, as our host star expands to become a red giant and then tears its body to pieces to condense into a white dwarf.
What is the lifetime in years of a star with a mass 5 times that of the sun?
A 5 solar mass star has only five times more hydrogen fuel than the Sun, but (the star’s luminosity)/(the Sun’s luminosity) = (5/1)4 = 625! Its lifetime = 1/(5/1)(4-1) × 1010 years = (1/125) × 1010 years = 8.0 × 107 years.
What are massive stars called?
Also, when more massive stars become red giants, they become so bright and large that we call them supergiants.
What are the three end stages of stars?
Three end stages of stars are:
- White Dwarf.
- Neutrons Star.
- Black Hole.
What are massive stars?
A massive star is a star that is larger than eight solar masses during its regular main sequence lifetime. Massive stars are born, just like average stars, out of clouds of dust called nebulae. A quick main sequence phase, where hydrogen continues to be fused into helium during a stable portion of the star’s life cycle.
What are the end stages of stars?
Three and stages of stars are white dwarf, neutron star and a black hole.
What are the stages of a star life cycle?
Science Project on the Life Cycles of Stars Heavy stars turn into supernovae, neutron stars and black holes whereas average stars like the sun end life as a white dwarf surrounded by a disappearing planetary nebula.
How many times larger than the sun is a massive star?
About half of all known stars are more massive; about half have less mass. At the top end of the scale, the most massive known star in the sky is R136a1, a star more than 300 times as massive as our sun. And it’s not alone in dwarfing Earth’s dominant star.
Which star is more massive than the sun?
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun.
What are the stages of the life cycle of stars?
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. 1. Giant Gas Cloud
What are the different types of stars?
Stars that are a similar size to the Sun follow the left hand path: red giant star \\ (\\rightarrow\\) white dwarf \\ (\\rightarrow\\) black dwarf. Stars that are far greater in mass than the Sun follow the right hand path: red super giant star \\ (\\rightarrow\\) supernova \\ (\\rightarrow\\) neutron star, or a black hole (depending on size)
What happens to low mass stars after the red giant phase?
After the red giant phase, low mass stars follow a different evolutionary path than more massive stars. For this reason, we are going to first consider what happens to low mass (less than 8 times the mass of the Sun) stars as they progress past the red giant phase.
How does a star change over its course of life?
A star converts hydrogen atoms into helium over its course of life at its core. Eventually, the hydrogen fuel runs out, and the internal reaction stops. Without the reactions occurring at the core, a star contracts inward through gravity causing it to expand. As it expands, the star first becomes a subgiant star and then a red giant.
