Which stars have longer lifetimes massive stars or less massive stars explain why?
Less massive stars have longer lifetimes because they are burning the hydrogen in their cores at a slower rate than more massive stars.
Thereof, which is the first stage of a star's life cycle?
The gas in the nebula begins to glow. This is the first step in the life cycle of a star. It is called a protostar. Thereof, what is the life cycle of a star in order? 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.
One may also ask which star has the longest main sequence lifetime?
The stars with the longest lifetimes are red dwarfs; some may be nearly as old as the universe itself. Red Dwarf Stars. Astronomers define a red dwarf as a star having between about 0.08 and 0.5 times the mass of the sun and formed primarily of hydrogen gas. Luminosity and Lifetime. Nuclear Fusion. Life Cycle of Stars. Which of the following main sequence stars is the least luminous? Alpha Centauri A is the least luminous because its absolute magnitude is the largest (+4.4). Which star has the highest surface temperature? Spica, with a spectral type of B1 (the closest to O in OBAFGKM), has the highest surface temperature.
Which main sequence stars have the shortest lifetimes quizlet?
Terms in this set (13) Post-main-sequence stars lose up to 50 percent of their mass because. The most massive stars have the shortest lifetimes because. When the Sun runs out of hydrogen in its core, it will become larger and more luminous because. When compressed, ordinary gas heats up but degenerate gas does not.
- Why does Mercury have less Maria?
There is virtually no space between stars and planets to scatter light to our eyes because space is a perfect vacuum. They see black with no light reaching their eyes.
- Why does snow have less friction?
Some of the moons of Saturn have conditions that may support life.
- Which type of galaxy is no longer forming stars?
There is a potential for life. It seems unlikely that life could exist on the surface of a cold planet. Water is rock-like at such cold temperatures. Some think that there could be an ocean in the interior of the dwarf planet.
- At which element does element formation stop in massive stars?
- Does Mars have less gravity than Earth?
- Do Aries have less friends?
