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 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.
The main sequence has a limit at the lower end because?
the main sequence has a limit at the lower end because as a star's mass decreases, its core temperature and pressure decrease too. This eventually causes the nuclear fusion reactions in the core to stop, leading the star to move off the main sequence.
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.
What color is the star alioth?
Alioth is a white star nearing the end of it's main sequence. Hope this helps! (:

Is a red giant star considered to be a main sequence star?
No. Red giants are not on the main sequence.
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.
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.
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.
The main sequence has a limit at the lower end because?
the main sequence has a limit at the lower end because as a star's mass decreases, its core temperature and pressure decrease too. This eventually causes the nuclear fusion reactions in the core to stop, leading the star to move off the main sequence.
Main sequence star distance from earth?
The sun is a main sequence star, so 1 AU.

What is a stabilized star?
Main-Sequence star
How long will Spica stay on the main sequence?
Spica is a dual star system, with the two members too close for resolution by the best telescopes. The larger, primary star is a blue-white giant, and does have the potential to end it's life as a supernova. The primary is not a main sequence star. The secondary, about 70% the size of the primary, is a main sequence star, also blue white.
