A star's lifetime depends on what?
It depends on its size. Smaller stars- main-sequence, red giant, planetary nebula, white dwarf, black dwarf Bigger stars- main-squence, red giant, supernova, neutron star.
What is a star's main fuel during its lifetime?
hydrogen
How does the main-sequence lifetime of a star compare to its entire fusion lifetime?
Stars spend about 90% of their fusion lifetimes on the main sequence.
Is the main sequence lifetime of a low mass star the same as the lifetime of the sun?
No. The less massive a star, the longer it will last. A main sequence star half the mass of the sun can be expected to last about 5 times longer.
What is a star's main fuel doing its lifetime?
For most of a star's life, the main fuel is protium (hydrogen-1), which is fused into helium-4.
What percentage of a star's total lifetime is spent on the main sequence?
Roughly 90% of a star's total lifetime is spent on the main sequence, where it fuses hydrogen into helium in its core. After this stage, the star will evolve off the main sequence and follow a different path, such as becoming a red giant or a supernova.
Where does a star spend most of its lifetime on the h-r diagram?
On the main sequence.
The star 61 cygni B has a main sequence lifetime of about how many years?
10¹¹ years
Where does a star spend most of its lifetime on an h r diagram?
MAIN-SEQUENCE The average star spends 90% of its life as a hydrogen burning MS star.
Have scientists seen a star form or witnessed the formation of a star?
Not exactly: Star formation is believed to be a slow process, compared to a human lifetime; scientists have, however, seen stars in different phases of their formation.
Main sequence lifetime is determined by what?
The mass of the star. The bigger it is, the faster it will burn through its fuel supply.
How does a star's mass indicate lifetime?
When a star is at the end of its lifetime its mass increases.
