Web28 de abr. de 2024 · However, with an instrument like CUBES we are no longer restricted to a few elements; a richer chemical pattern of the heavy elements can finally be mapped with such an instrument. Understanding the formation of an element like Sr in detail is of great interest, as it is one of the lower-Z n-capture elements, which lies close to the first … Web17 de mar. de 2024 · Answer: After helium is exhausted in the core of a star, it will continue in a shell around the carbon-oxygen core. This can then form oxygen, neon, and heavier elements via the alpha process. In this way, the alpha process preferentially produces elements with even numbers of protons by the capture of helium nuclei.
