Is a star a pure substance?
No - a star would not be a pure substance. Our understanding of how stars function includes a continuous fusion of hydrogen to form helium and, depending on the star, possibly further fusion of the helium into even heavier elements. Once formed, these heavier elements do not just go away or change back into helium so stars will always be composed of a mixture of hydrogen and the byproducts of fusion.
