Question

Quizplus · Accepted Answer

Low-mass red giant stars play a crucial role in the cosmic production of carbon, one of the essential elements for life as we know it. During their red giant phase, these stars undergo a process known as helium fusion or the triple-alpha process, where three helium nuclei are combined to form carbon. This process significantly contributes to the carbon abundance in the universe, including the carbon atoms found in our bodies.
