A star evolves off the main sequence when it runs out of hydrogen fuel in its core. This causes the core to contract and heat up, leading to the expansion of the star's outer layers. This marks the beginning of the star's evolution into a red giant or supergiant, depending on its mass.

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.
A star located off the main sequence indicates what?
A star located off the main sequence indicates that the star is at a different stage in its life cycle. This could be due to factors such as age, mass, or chemical composition. Some common types of stars found off the main sequence include red giants, white dwarfs, and supergiants.
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 stars are also called stars?
Main sequence stars are also called dwarf stars because they are in a stable phase of their lives where they are fusing hydrogen into helium in their cores. They are the most common type of star found in the universe. Examples of main sequence stars include our Sun and Proxima Centauri.
A solar mass star will evolve off the main sequence when?
A solar mass star will evolve off the main sequence when it exhausts its core hydrogen fuel and transitions to burning helium in its core. This change in nuclear fusion process causes the star to expand and become a red giant as it moves towards the later stages of its evolution.

When does a star lose its main sequence?
Stars don't "lose" their "main sequence", because it's not something a star can "have" in the first place.Stars are more properly described as being "on" or "off" the "main sequence", and "sequence" isn't a good word for it anyway, because it implies that there is an actual sequence of events involved; in fact, the normal life sequence of a star has it going off the main "sequence".It may help if you stop thinking of them as "main sequence" stars and start thinking of them as either dwarfs or type III stars.

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.
What will burn through its fuel first a main sequence star or a super giant?
Main sequence stars do not really exist - well they do, but read on. Main sequence is a stage in a stars life - where it converts hydrogen into energy, not a particular star or type of star. All stars go through a main sequence, from the smallest to the largest.However, in general, the larger the star, the faster it will burn off it's fuel.
Outline the history and probable future of your sun?
In the past it was a main sequence star. In the future it will be a giant star and will cool off.
When was Off the Main Sequence created?
Off the Main Sequence was created in 2005-11.
How many pages does Off the Main Sequence have?
Off the Main Sequence has 738 pages.
What is the ISBN of Off the Main Sequence?
The ISBN of Off the Main Sequence is 1-58288-184-7.
