During this time, nuclear burning of hydrogen builds up a helium residue in a stellarcore causing an increase in pressure and temperature. It is condensed and may be observed with small telescopes, but larger apertures are required to resolve its stellarcore.

A sufficiently large and hot stellarcore may generate gamma-rays energetic enough to initiate photodisintegration directly, which will cause a complete collapse of the core.

Once the stellarcore is sufficiently dense, hydrogen becomes steadily converted into helium through nuclear fusion, releasing energy in the process.

From 0.3 to 1.2 solar masses, the region around the stellarcore is a radiation zone, separated from the overlying convection zone by the tachocline.
