White dwarves, neutron stars, and black holes.
A protostar; also a brown dwarf.
You would look for high-energy electromagnetic radiation like gamma rays emitted from the star. This type of radiation is produced during nuclear fusion reactions when light atomic nuclei combine to form heavier nuclei and release energy. Detection of gamma rays can provide evidence that nuclear fusion is taking place in the core of a star.
nuclear fission and nuclear fusion
No, fusion is a type of nuclear reaction.
A type of nuclear reaction
The stars produce their heat from nuclear fusion reactions. Work on earth to produce controllable nuclear fusion is concentrating on one particular reaction, between deuterium and tritium, because it is the easiest to get going (though hard enough!). Stars operate with other reactions but all of the nuclear fusion type. You can read more in Wikipedia 'Nuclear fusion'
Helium is converted into carbon during the final stage of fusion in a star called a red giant. This process occurs when helium fusion in the core of the star gives rise to carbon as the result of nuclear reactions.
Nuclear fusion.
Usually a nuclear physicist.
False
Nuclear fusion is the type of nuclear reaction that occurs in stars. Older stars with a collapsing center can exceed a temperature of one hundred million Kelvin.
