I feel like iron in the blood gets a lot of airtime, but literally all the carbon in our bodies is star stuff too. As is the oxygen making up the water. And almost everything else.
- chasil 10mo agoThe CNO cycle dominates fusion in stars much larger than our own. The carbon transitions to nitrogen and oxygen repeatedly. https://en.wikipedia.org/wiki/CNO_cycle https://en.wikipedia.org/wiki/CNO_cycle
- gus_massa 10mo agoFrom your link: > This result therefore paves the way towards a direct measurement of the solar metallicity using CNO neutrinos. Our findings quantify the relative contribution of CNO fusion in the Sun to be of the order of 1 per cent; I find it amazing that we can analize the composition of the core of the Sun measuring the energy of the neutrinos. (Photons are not useful, because they bounce a lot of times before escaping from the Sun, so they provide only information about the outher layers.)
