Classic text and essential primer for understanding stellar evolution and nuclear astrophysics. This was a required supplementary text for my upper division undergraduate course, but can be used in for a graduate course as well.

Evolution And Nucleosynthesis

The lowest mass stars can only synthesize helium. We understand now why some elements like carbon, oxygen, silicon, and iron are common and the heaviest elements like gold, mercury, and uranium are so rare. In the cores of stars and in supernova explosions, new atoms are manufactured from nuclear fusion reactions.

The use of the word created here is different than what is normally meantby scientists. These reactions created theheavier elements from fusing together lighter elements in the central regionsof the stars. These elements will be later incorporated into giant molecular clouds and eventually become part of future stars andplanets (and life forms?) although the particulars of various nucleosynthesis processes are beyond the scope of this website, it is important to note a couple of things the stellar nucleosynthesis theory correctly predicts the observed abundances of all of the naturally-occuring heavy elements seen on the earth, meteorites, sun, other stars, interstellar clouds---everywhere in the universe.

You will find out where thehydrogen and most of the helium atoms came from in the the atoms heavier than helium up to the iron and nickel atoms were made in the cores of stars (the process that creates iron also creates a smaller amount of nickel too). The synthesized elements are dispersed into the interstellar medium during the planetary nebula or supernova stage (with supernova being the best way to distribute the heavy elements far and wide). However,now that you know about stellar nucleosynthesis, i need to be more carefulabout what is being created from scratch and what is being re-used.

That oxygen then goes into the air and you breathe it in. All of the atoms on the earth except hydrogen and most of the helium are recycled material---they were not created on the earth. All of the rest of the elements of the universe wereproduced by the stars in nuclear fusion reactions.

In defensei want you to know that practically everyone, except for the astronomerresearching stellar evolution, uses this loose meaning of creation. Elements heavier than iron are madeinsupernova explosions from the rapid combination of the abundant neutrons withheavynuclei. To be more correct i should have said that the oxygen atomswere moved or broken off from one set of compounds carbon dioxide ( and a molecule ofcarbohydrate made of carbon atoms, hydrogen atoms, and oxygen atoms( each atomis rearranged or re-used.

The art 2 science camp is an extension of our after-school programs which seek to ignite stellar imaginations through an integrated steam approach to learning. In chemical reactions, different atoms or combinations of atomsare said to be produced or created when a reaction takes place. There is necessarily a lag between the beginning of the universe and the beginning of life.

Big Bang nucleosynthesis - Wikipedia


In physical cosmology, Big Bang nucleosynthesis (abbreviated BBN, also known as primordial nucleosynthesis, arch(a)eonucleosynthesis, archonucleosynthesis, protonucleosynthesis and pal(a)eonucleosynthesis) refers to the production of nuclei other than those of the lightest isotope of hydrogen (hydrogen-1, 1 H, having a single proton as a nucleus) during the early phases of the Universe.

Evolution And Nucleosynthesis

Stellar nucleosynthesis - Wikipedia
Stellar nucleosynthesis is the theory explaining the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions between atoms within the stars. Stellar nucleosynthesis has occurred continuously since the original creation of hydrogen, helium and lithium during the Big Bang.

  • Stellar Nucleosynthesis - Astronomy Notes


    Hydrogen and helium and some lithium, boron, and beryllium were created whenthe universe was created. There is necessarily a lag between the beginning of the universe and the beginning of life. Massive stars( 8 solar masses) can synthesize helium, carbon, oxygen, neon, magnesium, silicon, sulfur, argon, calcium, titanium, chromium, and iron (and nickel). These reactions created theheavier elements from fusing together lighter elements in the central regionsof the stars. Except forthe hydrogen and most of the helium atoms, all of thematerials around you, in the food you eat and drink, in the air you breathe,in your muscles and bones, in the paper and ink or toner of this book (or computer screen you are reading), everything (!) are made of atoms that were created in the stars.

    All of the rest of the elements of the universe wereproduced by the stars in nuclear fusion reactions. In order to create a terrestrial planet like the earth (and life on such a planet), enough of the heavy elements have to be created in previous generations of stars and then concentrated in the interstellar clouds to collect into sizable chunks around forming stars. The program introduces participants to the fundamentals of the extremely small domain of atomic nuclei and its connection to the extremely large domain of astrophysics and cosmology. For example,in the ,i said that oxygen was produced in the photosynthesisprocess of plants.
