Hydrogen burning vs Hydrogen fusing - Astronomy Stack …

WebWhen the sun collapsed out of the solar nebulae, gravity was balanced by pressure, and possibly by magnetic fields, until the sun evolved into a stable “main sequence” star some 5×10 9 years ago. Initially, hydrogen burning was confined to the sun's extreme core, and its luminosity was then 70% of its current value. WebThe stage of hydrogen burning in the core is projected to last about 1010 years for the Sun, implying that it is about halfway through this stage. The diminishing number of protons in the centre of the star causes this region to contract slowly, and consequently, the temperature rises. bony growths on gums in mouth
