, of any star in terms of its mass: ... So it has already converted about half the hydrogen in its core into helium (see text, Fig. 20.2 and here ... the Sun will be a red giant for about 100 million years or so, as its helium core slowly continues to contract and get hotter. But then something remarkable happens.
