In the sun the product of the nuclear fusion is light energy and heat energy. It also created helium from the isotopes deuterium and tritium.
Sun energy is produced by the fusion of two hydrogen atoms under immense pressure and heat in the core of the sun. The chemical energy (energy stored in the bonds of atoms) is released during this fusion.
Red Giant effect: When the primary fuel of the sun depleted, the fusion of 2H -> He stop at the core and the core contract. The surface is still burning but greatly expand with lower temperature from existing sun but a lot larger. Finally, when the sun really burn out it, the collapse remain mass become White Dwarf. All is part of stellar evolution. Process of Sun burning is Nuclear Fusion Reaction, refer to it as burning usually make confuse that the sun is chemically burn and require oxygen.
The word you're looking for is... Fusion
The conversion of Hydrogen into Helium (nuclear fusion).
The process of fusion. The sun makes heat by fusing hydrogen atoms. Hydrogen is the lightest element, and in the process of fusion, the lighter the element being fused, the more energy (heat) is produced.
A fusion reaction generates helium as a waste product.
Fusion occurs in the core of the sun and other stars.
Nuclear reaction
Fusion.
This reaction, known as nuclear fusion, converts hydrogen atoms into helium. The by-product of nuclear fusion in the Sun's core is a massive volume of energy that gets released and radiates outward toward the surface of the Sun and then into the solar system beyond it.
The main chemical reaction that fuels the sun is nuclear fusion. In the sun's core, hydrogen nuclei combine to form helium nuclei, releasing a large amount of energy in the process. This fusion process powers the sun and produces sunlight.

Fusion Reaction of Hydrogen
Nuclear fusion. Hydrogen atoms combine to become helium, and as a product if that reaction a tiny amount of energy is released as an explosion.
The hydrogen in the Sun is fuel for the nuclear fusion reaction.
