High Mass Star Life Cycle

Like low-mass stars high-mass stars are born in nebulae and evolve and live in the Main Sequence.

High mass star life cycle. A contracting cloud is then called a _____. High Mass Stars Neutron Star Red Super Giant Neutron stars are are supposedly cataloged over 10000000000 years old although a large majority of pulsars a neutron star subclass are 100000 and 300000000 years old. Supernova leaves neutron star behind.

Life span means how long the star lives from the initiation of fusion to supernova. H fuses to He in core. Remainings of a Massive-star Supernova Event This step forms a blurry nebula in space from the debris of the Supernova.

And The High-Z Supernova Search Team. H fuses to He in shell around He core. The size of the star and the rate of fusion.

Stars with different masses grow and change throughout the different stages of their. Stage 1 A star consists of two gases--hydrogen and helium. Star - Star - Evolution of high-mass stars.

And find homework help for other Science questions at eNotes. If the size of the star is massive or it has a high mass the star will have a large amount of hydrogen. The life span of large stars is much less than small and medium mass stars.

If the remnant of the explosion is 14 to about 3 times as massive as our Sun it will become a neutron star. As the gas spins faster it heats up and is known as a protostar. The gravitational potential energy from the mass of the star causes extremely high temperatures about 170 million degrees Celsius to build up in the core.
