Web7. The short answer is no: there isn't a agreed theoretical distinction between red giants and red supergiants. The source of confusion is that the red giant branch (RGB) is a theoretical concept, but the Yerkes spectral classification also defines a red giant observationally. So when astronomers talk about red giants, it isn't necessarily ...
