A protostar; also a brown dwarf.
Not nuclear, it takes an extremely hight temperature for Fusion to occur with in the sun or any other star. ADDED: Yes "nuclear". Fusion is one of the two type of nuclear reaction, the other being Fission.
Nuclear fusion. Stellar fusion involves a ton of different fusion reactions throughout the star's life. The primary and (usually) the longest burning is the fusion of hydrogen into helium. This consumes a great number of the nuclear energy in the sun, and it usually accounts for the type of fusion that goes on for most of the life of the star. This is the process.
It is thermo-nuclear fusion. That is two atoms of hydrogen aredraw to each other by gravity. They become so close they fuse together and release energy in the process. This happens billions of times over in a given locality in space, and as such a star forms.
All red giant stars will start helium fusion when their core is compressed.
Brown dwarf

White dwarves, neutron stars, and black holes.
No, fusion is a type of nuclear reaction.
nuclear fission and nuclear fusion
A type of nuclear reaction

Fusion is the type of nuclear reaction that fuels your solar system.
