Ph217:aug-dec2003 1 nucleosynthesis and stellar evolution nuclear fusion rates are extremely sensitive to temperature in order to understand why this is so, we need to examine how a fusion process. During pre-main sequence evolution, lithium can be destroyed by nuclear reactions for example: p + 7 li = 4 he + 4 he the temperature required is a ~ 3 x 10 6 k for 7 li, and at lower temperatures for 6 li - so this can. Editorial reviews stellar evolution and nucleosynthesis provides a fine, insightful, and remarkably complete introduction to modern astrophysics that is both well written and illustrated. Stellar nucleosynthesis occurs at many different stages of stellar evolution, from main-sequence stars all the way to supernovae in perhaps the simplest nucleosynthesis reaction in the stellar core, hydrogen is produced from helium.
