In the second phase, it radiates away its energy and fusion reactions cease, as the central star is not heavy enough to generate the core temperatures required for carbon and oxygen to fuse.
I det andet stadium udstråler den sin energi, og alle fusionsreaktioner ophører, fordi stjernen ikke er tung nok til at frembringe de kernetemperaturer, som ville kræves for at starte fusion af carbon og ilt.
