What else can I help you with?
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.
Is most stars sequence stars?
"main sequence" is the tern.
Why are there not many stars on the upper main sequence?
There are fewer stars on the upper main sequence because these stars have shorter lifespans compared to their lower-mass counterparts. High-mass stars burn through their nuclear fuel quickly, exiting the main sequence in a relatively short time, often in just a few million years. In contrast, lower-mass stars can remain on the main sequence for billions of years, leading to a greater abundance of them. Consequently, the upper main sequence is less populated due to the rapid evolution of high-mass stars.
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.
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.
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.
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 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 fuel is used with the main sequence stars?
gas, and other vibrate radiations.
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 are the two stars that are not in the main sequence?
There are billions of stars that are not on the main sequence.
What fuel is being burned by main sequence stars?
Hydrogen is being "burned" into helium.
What are the stars in the main sequence?
The smallest stars in the main sequence are the stars with cooler surface temperatures.
Is most stars sequence stars?
"main sequence" is the tern.
What kind of stars are 90 of all Stars?
main sequence stars , our sun is also a main sequence star
