A "main-sequence star" is one that fuses hydrogen into helium. Eventually, the star will run out of this specific type of fuel - in other words, it won't have enough hydrogen (at least, near its core) to continue this process.

What does it mean when a star goes off the main sequence?
When a star "goes off the main-sequence" it generally means the star has run out of hydrogen fuel and is beginning the post-main-sequence or its end of life phase. The main sequence of a star is the time where it is no longer just a proto-star but is burning hydrogen as a primary source of fuel.
What color is the star alioth?
Alioth is a white star nearing the end of it's main sequence. Hope this helps! (:
What type of star would be shown at the lower right end of the main sequence on the H R diagram?
Depending on how "low" on the chart it will either be a red dwarf or a PMS (Pre-main sequence) star.
Do Stars spend most of their life span as main-sequence stars?
Yes Star spend most of their life span as a main sequence star. A star end will depend on its size in life the end of a start can be a red giant to supernova, a white dwarf, pulsar, or black hole.
Name an example of a main sequence?
The sun is a main sequence star

Is a red giant star considered to be a main sequence star?
No. Red giants are not on the main sequence.

Does a red main sequence star have fusion?
A red main sequence star would be a red dwarf or a branch red giant. To be on the main sequence, you have to have hydrogen nuclear fusion.
Do Stars spend most of their life span as main-sequence stars?
Yes Star spend most of their life span as a main sequence star. A star end will depend on its size in life the end of a start can be a red giant to supernova, a white dwarf, pulsar, or black hole.
When does the main sequence star phase of a star end?
The "main sequence" is the region (on the HR diagram) for stars which burn hydrogen-1. Once stars use up most of their hydrogen-1 (and have significant amounts of helium-4), they leave the main sequence.
Main sequence star distance from earth?
The sun is a main sequence star, so 1 AU.
Name an example of a main sequence?
The sun is a main sequence star
How do red dwarfs differ from a main sequence star?
It's the size. A dwarf star has reached the end of the road and has collapsed. It's a little old star and people don't notice it, mostly.
What is a stabilized star?
Main-Sequence star
Why is Sirius not a main sequence star?
Sirius is not a single star but a binary star system consisting of a white main sequence star and a white dwarf.
