Does the H-R diagram reveax)u 7w.mskdzs02 + lxpl anything ab(edvl g))io g9out the core of a star?
参考答案:
Although the H-R diagram only directly relates the surface temperature of a star to its absolute luminosity (and thus doesn’t directly reveal anything about the core), the H-R diagram does provide clues regarding what is happening at the core of a star. Using the current model of stellar evolution and the H-R diagram, we can infer that the stars on the main sequence are fusing hydrogen nuclei to helium nuclei at the core and that stars in the red giant region are fusing helium and beryllium to make heavier nuclei such as carbon and that this red giant process will continue until fusion can no longer occur and the star will collapse.
