Which element stops fusion in a high mass star?
iron
What stars 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. Supernovae release these elements into space making them available to be incorporated within later generations of stars.
What are three differences between a low mass star and a high mass star?
Both, a low mass Star and a High mass Star will Start off with fusing hydrogen into Helium, though a high mass Star will burn it faster because of increased pressure and temperature in the core. A second difference is the ability to create heavier elements. This is called a Neutron Star and has a size of rougly 20km.
Where do high mass stars form?
Stars form within dense clouds of dust and gas located in the interstellar medium of a galaxy. Gravity causes these clouds to collapse in on themselves, with small disturbances within a cloud causing denser clumps of matter to form.
What is the stages of a high mass star?
The exact stages of evolutions are: Subgiant Branch (SGB) – hydrogen shell burning – outer layers swell. Red Giant Branch – helium ash core compresses – increased hydrogen shell burning. First Dredge Up – expanding atmosphere cools star – stirs carbon, nitrogen and oxygen upward – star heats up.
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 event occurs at the end of the life of a high-mass star?
The ultimate fate of a star depends on its initial mass. A massive star ends with a violent explosion called a supernova. The matter ejected in a supernova explosion becomes a glowing supernova remnant.
What are the three types of star deaths?
With this in mind, we will consider the death of stars and group them into three categories according to mass:
- Low-Mass Stars (0.5 solar mass or less)
- Medium-Mass Stars (0.5 solar mass to 3.0 solar mass)
- Massive Stars (3.0 solar masses or larger)
