Which process produces the energy radiated by the star when it become a main sequence star?
nucleur fusion
Why does a star produce light?
Because of nuclear fusion! The nuclear fusion releases energy which produces light.
Why are stars so important?
Stars play a variety of roles. First and foremost, the sun is a star. It provides the heat and light necessary for life of Earth. Stars also create most of the elements we find. Before stars started forming all matter in the universe consisted of hydrogen, helium, and trace amounts of lithium. All other elements have since been made in the thermonuclear furnaces of stars.
Do Hotter stars age more slowly then cooler stars?
The surface temperature is not a reliable indicator about how long a star will last. However, the total energy output is. If a star produces a lot of energy, it will burn through its fuel faster.
What is the name of the process inside a star that produces the star's energy?
Nuclear fusion. This is the process of fusing two atoms together to make a heavier one. Don't confuse this with nuclear fission, though. Fission is the process of splitting atoms apart (that is what we use for nuclear power plants.)
What produces a star's energy?
The nuclear fusion that goes on within the star.
Is a star important to the solar system?
Yes, a star produces energy to the solar system.
What produces light in a star?
energy released during the process of nuclear fusion in the star's core
Which process produces the energy radiated by the star when it become a main sequence star?
nucleur fusion
What is the central portion of a star that produces energy through nuclear reactions?
core
Why can the fusion of iron into heavier elements not support a star?
The fusion of iron into heavier elements cannot support a star because it requires more energy than it produces, leading to a loss of energy and the collapse of the star.
Is white dwarf a dead star?
Yes - in the sense that it no longer produces energy. In other words, the star has run out of fuel for nuclear fusion.
What chemical reaction produces heat and energy in a star?
it is not a chemical reaction. It is a nuclear reaction and it is called fusion.
Why does a star produce light?
Because of nuclear fusion! The nuclear fusion releases energy which produces light.

What produces the Sun's energy?
Fusion produces the Sun's energy .
Why do stars cool when the fusion cycle gets to iron?
Unlike lighter elements, fusing iron consumes more energy than it produces. This does not, however, cause a star to cool. Once a star gets to the point of fusing iron, the core stops producing energy and without the pressure from the heat it produces, the core collapses while the rest of the star is blasted away in an explosion.
