hydrogen burning

(H burning, hydrogen fusion)
(any fusion reaction starting with hydrogen)

Hydrogen burning (or hydrogen fusion) is fusion of hydrogen nuclei, mainly the triple alpha process or CNO cycle. The basis for the minimum size of a main sequence star is that it is hot enough at the core to trigger 1H burning.

The phrase hydrogen burning may sometimes be meant to include deuterium, but often what is meant is 1H.
