What are the stages in a stars life cycle?
Stars come in a variety of masses and the mass determines how radiantly the star will shine and how it dies. 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.
What are the 3 end stages of stars?
Three end stages of stars are:
- White Dwarf.
- Neutrons Star.
- Black Hole.
What are the three end stage of stars?
Three and stages of stars are white dwarf, neutron star and a black hole.
What is the next stage in a stars life after the main sequence phase quizlet?
After the main sequence, the star moves expands to a red giant. In this stage, the star relies on the second element of the periodic table, helium. after the star has finished with the helium, the star implodes into the white dwarf stage, which relies on carbon. You just studied 18 terms!
How does the life cycle of a star end?
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.
What are the seven main stages of a star?
Seven Main Stages of a Star 1 Giant Gas Cloud. A star originates from a large cloud of gas. 2 Protostar. When the gas particles in the molecular cloud run into each other, heat energy is produced. 3 T-Tauri Phase. 4 Main Sequence. 5 Red Giant. 6 The Fusion of Heavier Elements. 7 Supernovae and Planetary Nebulae.
What happens in the main sequence of a star?
The main sequence phase is the stage in development where the core temperature reaches the point for the fusion to commence. In this process, the protons of hydrogen are converted into atoms of helium. This reaction is exothermic; it gives off more heat than it requires and so the core of a main-sequence star releases a tremendous amount of energy.
What happens when a star reaches the red giant phase?
Once a medium size star (such as our Sun) has reached the red giant phase, its outer layers continue to expand, the core contracts inward, and helium atoms in the core fuse together to form carbon. This fusion releases energy and the star gets a temporary reprieve.
