Luminous
All things, except black holes, are luminous. That includes stars. You might think that some other things are not luminous but that's because you can't see the kinds of light that they emit.
Our sun actually is a star so yes, stars are luminous. The produce huge amounts of light and heat through nuclear fusion of hydrogen.
