Stars form in clouds of gas and dust called nebulae or stellar nurseries that can form anywhere between a few dozen to … WebbANSWER: Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most massive) to trillions of years (for the less massive), considerably more than the age of the universe.
Stellar nucleosynthesis is the creation (nucleosynthesis) 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 elements. It explains why the observed abundances of elements change ov… Webb1 sep. 1990 · There are three major sources responsible for the synthesis of the elements: comological nucleosynthesis in the big bang, nucleosynthesis during stellar evolution, and nucleosynthesis in the interstellar medium induced by cosmic rays; this presentation focusses on the second of these processes.
