WebVigarano 1623-5 contains nucleosynthetic anomalies in a wide range of minor and trace elements including Cr, Zn, Sr, Ba, and Sm (Loss et al., 1994). However, it is notable that the largest anomalies occur as deficits in both 50 Ti and 48 Ca, which cannot be simply explained by a “carrier phase” within 1623-5 or its isotopic twin, C1 (Loss et al., 1994 ). Web21 apr. 2024 · The impact of convection, rotation, mass loss, and binarity on massive star evolution is reviewed, with a focus on the effect they have on the global nucleosynthetic products of the stars. 1.

Web8 mei 2012 · A star's energy comes from the combining of light elements into heavier elements in a process known as fusion, or "nuclear burning". It is generally believed that most of the elements in the universe heavier than helium are created, or synthesized, in stars when lighter nuclei fuse to make heavier nuclei. The process is called … Web22 jun. 2024 · Nucleosynthesis is the process of making new atomic nuclei from pre-existing nuclei, protons, and neutrons. Essentially, it is the creation of the elements of the periodic table. The two broad ways atomic nuclei form are by fusing together smaller nuclei and nucleons (protons and neutrons) or by breaking apart larger nuclei through fission ...
