Eventually the temperature reaches roughly 15 million degrees and fusion starts. The star begins to glow brightly and contracts. It is now a star, which will shine for millions to billions of years. WebIn the case of the Sun's core, it becomes degenerate when density is larger than 10 6 kg/m 3 (thousand times the density of water) temperature is near 20 million K. The Sun's helium core becomes degenerate early during the red giant phase of its life. In all the low mass stars, the helium core becomes degenerate during the red giant phase. purimmtopakku
