Nucleosynthesis of nuclei elements beyond the iron peak. nuclei beyond the iron peak (essentially iron to uranium) cannot be fused inside of stars, so they. It is this two stage process that is endothermic (see what effects besides "mass defect" cause the alpha ladder beyond iron 56 nickel 56 to be endothermic? now, given the possibility of rearrangement of the nucleons amongst the nuclei in the core then what should happen is that they equilibriate to the nucleus which has the highest binding.
$\begingroup$ thank you for clarifying: the iron we see in stellar atmospheres was produced in supernovae of other stars. i knew it, but misinterpreted your answer. dredge up processes may reveal elements like technetium being formed within a star, but they do not have the time to reveal iron production. $\endgroup$ –. So, more accurately, iron is the heaviest element produced in stellar nucleosynthesis in any significant quantity that produces more energy in fusion than the fusion consumes. this is called the alpha process ladder. keep adding alpha particles to the newly generated nuclei, until you stop getting more energy out than you put in. The heavier the atom, the more energy it needs to start a fusion. on the periodic table, iron is about the threshold at which fusion starts consuming more energy than it releases and becomes endothermic (it consumes heat). to sustain fusion reactions beyond iron, the star would need a sufficient outside source of energy, which it doesn't have. Stellar structure and evolution. stars are the source of almost all of the light our eyes see in the sky. nuclear fusion is what makes a star what it is: the creation of new atomic nuclei within the star’s core. many of stars’ properties — how long they live, what color they appear, how they die — are largely determined by how massive.

Stellar nucleosynthesis. in astrophysics, stellar nucleosynthesis is the creation of chemical elements by nuclear fusion reactions within stars. stellar nucleosynthesis has occurred since the original creation of hydrogen, helium and lithium during the big bang. as a predictive theory, it yields accurate estimates of the observed abundances of. The nuclear fusion for the reactions 2 h(d, n) 3 he, 2 h(d,γ) 4 he at low deuterons energy and cold nuclear fusion. il nuovo cimento a 103 , 1647–1650 (1990). article ads google scholar.
