What happens with stars with higher masses?

The higher mass star evolves more quickly than its lower-mass companion. When the more massive star becomes a red giant it may lose some of its mass to its normal, hydrogen-burning companion.

What is the life cycle of high-mass stars?

High-mass stars have lives of 10 million years, versus 10 to 50 billion years or more for low-mass stars. At the end of a high-mass star’s fusion process, iron composes the star’s core. No nuclear fusion of iron is possible out of a high-mass star core, which has the same mass as our entire Sun.

When a high-mass star dies it becomes?

When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant. While most stars quietly fade away, the supergiants destroy themselves in a huge explosion, called a supernova.

What will a high-mass main sequence star evolve into?

red giants
Eventually, as stars age, they evolve away from the main sequence to become red giants or supergiants. The core of a red giant is contracting, but the outer layers are expanding as a result of hydrogen fusion in a shell outside the core. The star gets larger, redder, and more luminous as it expands and cools.

Which stars have a high mass?

High mass stars (stars with masses greater than three times the mass of the Sun) are the largest, hottest and brightest Main Sequence stars and blue, blue-white or white in colour. High mass stars use up their hydrogen fuel very rapidly and consequently have short lives.

What kind of death does a high mass star experience?

A massive star undergoing core collapse produces a Type II supernova. What happens to the core material that is not ejected depends on its mass. The photodisintegration of iron in the last stages of the massive star’s life releases protons that in turn react with electrons to form neutrons (equation 6.3).

What are the 7 stages of a high mass star?

Seven Main Stages of a Star

  • Giant Gas Cloud. A star originates from a large cloud of gas.
  • Protostar. When the gas particles in the molecular cloud run into each other, heat energy is produced.
  • T-Tauri Phase.
  • Main Sequence.
  • Red Giant.
  • The Fusion of Heavier Elements.
  • Supernovae and Planetary Nebulae.

What comes after a high mass star?

A massive star will undergo a supernova explosion. If the remnant of the explosion is 1.4 to about 3 times as massive as our Sun, it will become a neutron star. The core of a massive star that has more than roughly 3 times the mass of our Sun after the explosion will do something quite different.
