SN 1572

I have analyzed the supernova SN 1572 also called as Nova Tycho. It is one of the eight supernova visible to the naked eye in historical records. It was discovered on November 11, 1572 by Tycho Brahe.

This is its energy spectrum from JS9 with its most importants energy peaks.

Then, I have calculated each peak's percentatge and find out which elements they contain.

I have used this formula:

 

Here are my results:

 

This supernova has:

  • 11,33% of Scandium (Sc) which energy is 755.8721 eV.
  • 7,23% of Iron (Fe) which energy is 1377.5769 eV.
  • 34,24% of Germanium (Ge) which energy is 1935.0326 eV.
  • 8,10% of Kripton (Kr) which energy is 2449.0256 eV.

COMPARISON

I have compared my results with other scientific results. According to the scientific article The chemical abundances of Tycho G in supernova remnant 1572 by JOnay I. González et al (2009) the supernova SN 1572 contains niquel, iron, cobalt and lithium.

  • Based on my investigation, this galaxy is form of scandium, iron, germanium and kripton.

There is a coincidence in the presence of iron. It might also explain the presence of niquel and cobalt, which have similar energy like the iron. They can be representated in the peak 2 of the energy spectrum I achieved.

  • The other chemical elements that I have obtain doesn't match to the results other astronomers got.
  • What I have done is to find the eV of the tallest peaks of the JS9 energy spectrum and discover what element corresponds to that enery.

I have calculated the electronvolt of this elements with the transition  predetermined in this web (from the cap 3 to the 2). The atoms to jump from this capes have to be in a room temperature. Depending to the temperature, the element can have different quantum energy. What is the same, a eV number can be from different elements if they are moving arround differents capes.

It can be possible that the atoms are not moving from the capes I have work with and this might be the reason why my results does not match with the scientifics results.
