What makes a star stop being a sequence star?
Basically, the stars on the "Main Sequence" are the ones that fuse hydrogen-1 into helium-4. Once a star burns up its hydrogen-1 fuel, or doesn't have much left, it will start burning helium-4 into heavier elements. It is then that the star leaves the "Main Sequence".
What is the name for the portion of a star life cycle when it is using hydrogen for fuel?
Main Sequence.
What is the name for the portion of a star's life cycle when it uses hydrogen for fuel?
When a star is in the Hydrogen burning phase it said to be a Main Sequence star.
What category does a star belong in Main sequence star white dwarf red giant neutron star?
None of those is a main sequence star.
What is the nearest star in the main sequence is?
Most stars are on the main sequence; that includes red dwarves. Specifically, in this case, the closest known star - Proxima Centauri - is also the closest main-sequence star.
What is the main characteristic of a sequence star?
The defining characteristic of a main sequence star burns hydrogen to helium in its core.
What is the main predictor of where a star will spend most of the time on the main sequence and why?
The star's mass. More mass will make the star hotter, and will increase the pressure in the center; this will make the star burn its fuel faster.When a star is on the "main sequence", it burns hydrogen-1, converting it into helium-4.

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 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.
What element is the main fuel for main sequence stars for red giant?
Main sequence star: hydrogen-1. Red giants: helium-4.
What element is the main fuel for red giants main sequence stars?
Main sequence star: hydrogen-1. Red giants: helium-4.
What red giants element is the main fuel for main sequence stars?
Main sequence star: hydrogen-1. Red giants: helium-4.
What do all stars in main sequence have in common?
main sequence stars all are burning though fuel at asteadyrate in there cores. with the proton+proton chain our sun is a main sequence star
What is the main source of energy of a star as it grows in size to becomes a red giant?
A main sequence star burns hydrogen to helium. Once a main sequence star exhausts all of the hydrogen, it begins to expand and burn helium causing if to become a red giant.
What is the name for the portion of a star life cycle when it is using hydrogen for fuel?
Main Sequence.
What is the name for the portion of a star's life cycle when it is using hydrogen for fuel?
main sequence
