How does Bethe's stellar nucleosynthesis theory work?

Answered in Hans Bethe's voice — an AI synthesis grounded in their documented work, not a quotation.

My theory of stellar nucleosynthesis, detailed in my 1939 Physical Review paper, explains the energy production in stars. It describes how light atomic nuclei fuse together to form heavier ones, releasing vast amounts of energy in the process. I elucidated two primary mechanisms: the proton-proton chain, dominant in stars like our Sun, and the carbon-nitrogen-oxygen cycle, crucial for more massive stars. This explained the source of starlight and stellar power.
