How do main-sequence stars produce heat and light?

In: Astronomy, Planetary Science, Stars [Edit categories]

Answer:

Most main sequence stars, including sun, produce heat and light by smashing atoms together to create explosions. Eventually, when the atoms continue to combine, they become too big to combine, and the star dies out. Then, it kind of implodes, and the friction of it becoming too dense makes it expand greatly past its original size, only temporarily. Shortly after, it finally explodes.

How do stars produce light and heat?
Stars produce heat and light by harnessing the energy from Hydrogen fusion. This process releases a lot of energy, hence stars are hotter and brighter than the cold space around them. They do this...
How do stars produce their own heat and light?
The heat is generated in the core as Hydrogen is converted to helium, which releases heat energy. Light is produced as excited electrons move down to lower energy levels, giving off mass-energy in...
What causes the stars to produce heat and light?
Stars produce heat and light through nuclear fusion, elements are fused together due to extreme force on the atoms and when they fuse they let off energy
What produces heat and light in stars?
The heat and light emitted from stars is due to the nuclear fusion within their cores. Stars are so massive that their gravity crushes atoms so close together that their nuclei begin to snap...
What of these stars have the hottest core a white main-sequence star or an orange main-sequence?
First of all, there cant be a white main-sequence star. White would be a white dwarf, red a giant or super giant. There can be blue, yellow, orange, red and anything in between those i guess. The...
