Main sequence star: hydrogen-1.
Red giants: helium-4.
What else can I help you with?
What red giants element is the main fuel for main sequence stars?
Main sequence star: hydrogen-1. Red giants: helium-4.
What element is the main fuel for main sequence stars for red giant?
Main sequence star: hydrogen-1. Red giants: helium-4.
Are main sequence stars older than red giants?
No, red giants are generally older than main sequence stars, as red giants have no hydrogen left for fuel, and burn helium instead. where as Main Sequence stars burn hydrogen for fuel.
Stars spend most of their life span as giants?
Stars spend most of their life span in the main sequence phase, where they are fusing hydrogen into helium in their cores. After exhausting their hydrogen fuel, they will expand and cool down to become red giants before eventually evolving into white dwarfs or other stellar remnants.
What is the primary fuel of main sequence stars?
The primary fuel for all stars is hydrogen
Stars leave the main sequence when they?
Stars leave the main sequence when they have exhausted their core hydrogen fuel, causing them to expand into red giants or supergiants. This transition marks the end of stable nuclear fusion in their cores and the beginning of the next phase in their lifecycle.
What element is the fuel for Red Giants?
helium
The two types of stars that do not fall into the main sequence of an H-R diagram are?
The two types of stars that do not fall into the main sequence of an H-R diagram are white dwarfs and giant stars. White dwarfs are small, hot stars that have exhausted their nuclear fuel, while giant stars are large, luminous stars that have evolved off the main sequence due to changes in their internal structure.
What are the large cool stars that are not in the main sequence?
Red giants. They are medium and large stars that have used up all of their hydrogen and gave begun burning the helium. They begin to expand while they are in their "dying" phase. They will ultimately become a white dwarf if they were a medium sized star during their main sequence, or they will become a black hole or a neutron star if they were a large star during their main sequence.
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
Stars primaily burn what element as fuel?
Hydrogen.
When do stars become red giants?
Stars become red giants when they have exhausted their hydrogen fuel in the core and start burning helium, causing the outer layers to expand and cool. This expansion turns the star into a large, cool, and luminous red giant.
