Elements higher than iron cannot be formed through fusion as one has to supply energy for the reaction to take place. In a supernova explosion, neutron capture reactions take place (this is not fusion), leading to the formation of heavy elements. s-process and r-process Jagadheep built a new receiver for the Arecibo radio telescope that works between 6 and 8 GHz. These masers occur at sites where massive stars are being born. D from Cornell in January 2007 and was a postdoctoral fellow at the Max Planck Insitute for Radio Astronomy in Germany.However, we do see elements higher than iron around us. This is the reason why it is said that most of the stuff that we see around us come from stars and supernovae (the heavy elements part). After that, he worked at the Institute for Astronomy at the University of Hawaii as the Submillimeter Postdoctoral Fellow.
I must emphasize that in regard to stellar composition we know only the composition of the stellar photosphere, the outermost layer of a star from which nearly all light emanates.
Astronomers generally assume that a star begins in a thoroughly mixed state so that its photosphere represents the star’s original composition.
Nucleosynthesis has been invoked to explain the chemical abundances found in the universe.
I particularly discuss stellar nucleosynthesis, through the proton-proton chain, the CNO cycle, the triple alpha process, the r process and s process.
We also know the gross composition of galaxies, which represents the average composition of the stars contained by those galaxies.
These studies also yield composition gradients within galaxies.
A creationary theory of the chemical abundances that we see in the universe is most desirable.
In 1835 the French philosopher Auguste Comte opined that while we can learn much about the stars, their composition would forever be unknown to us.
For an independent study course at my high school, I am researching the formation of the elements, both light and heavy.
I have some basic understanding of how this is done, and I have also found some technical information that at this time I don't understand.
