By fusing Hydrogen to Helium and these elements into heavier ones.
In the cores of lower mass main sequence stars such as the Sun, the dominant process is the proton-proton chain reaction (pp-chain reaction). This creates a helium-4 nucleus through a sequence of chain reactions that begin with the fusion of two protons to form a nucleus of deuterium. The subsequent process of deuterium burning will consume any pre-existing deuterium found at the core. The pp-chain reaction cycle is relatively insensitive to temperature, so this hydrogen burning process can occur in up to a third of the star's radius and occupy half the star's mass. As a result, for stars above 35% of the Sun's mass, the energy flux toward the surface is sufficiently low that the core region remains a radiative zone, rather than becoming convective. In each complete fusion cycle, the p-p chain reaction releases about 26.2 MeV.
What else can I help you with?
The stage in which stars produce energy through the fusion of hydrogen into helium?
main sequence
During which stage do stars produce energy from the fusion of hydrogen into helium?
Stars produce energy from the fusion of hydrogen into helium during the main sequence stage of their life cycle. This is when a star is stable and balanced, and the fusion of hydrogen into helium in its core generates the energy that makes the star shine.
What is the main sequence stage?
The main sequence stage is a point in the stellar evolution of stars in the universe at which every star converts hydrogen into helium in its cores and releases huge amounts of energy.
Most stars are classified as which of these?
Most stars are classified as main sequence stars, including our Sun. Main sequence stars are in a stable stage of nuclear fusion, converting hydrogen into helium in their cores. This is the longest stage in a star's life cycle, lasting for billions of years.
Are most stars in our galaxy found in the main sequence?
Yes, the majority of stars in our galaxy, including our Sun, are found in the main sequence stage of their life cycle. The main sequence is a phase where stars are fusing hydrogen into helium in their cores, which is the most common stage of stellar evolution.
How does the protostar stage of a stars life cycle compare with the main sequence stage?
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.

What happens to main sequence stars when energy from fusion is no longer available?
The star will move on to its next stage of evolution, along the Red Giant branch.
Which types of stars is considered part of the main sequence?
Main sequence stars include dwarf stars like red dwarfs, yellow dwarfs (like our Sun), and blue dwarfs. These stars are in a stable phase of hydrogen fusion in their cores, where the energy generated by nuclear reactions supports the star against gravitational collapse.
Which life cycle stage are stars stable and why?
Stars are most stable during the main sequence stage of their life cycle. During this stage, stars maintain a balance between the inward force of gravity and the outward force of nuclear fusion in their cores. This equilibrium allows them to burn hydrogen efficiently and emit a steady amount of energy.
Nearly 90 percent of all-stars are at what point in their life cycle?
100% of all stars go through the Main Sequence stage. This is when they Fuse hydrogen into Helium. The length of this time depends on the density and composition of the star but they all do it.
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 types of stars are in the main sequence?
The thing the "main sequence" stars have in common is that they get their energy from the fusion of hydrogen (hydrogen-1 is converted into helium-4).
