Hydrogen is being "burned" into helium.
The primary fuel for all stars is hydrogen
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.
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
gas, and other vibrate radiations.
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.
main sequence stars of which colr use up their fuel supply in the shortest period of time? and why.
Main sequence star: hydrogen-1. Red giants: helium-4.
Main sequence star: hydrogen-1. Red giants: helium-4.
Main sequence star: hydrogen-1. Red giants: helium-4.
Factors that influence flame height include the amount of fuel being burned, the rate at which it is being burned, the presence of oxygen for combustion, and environmental conditions such as wind speed and direction. Additionally, the type of fuel being burned and the shape and size of the flame source can also impact flame height.
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.
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.
