Analysis the spectrum of NGC 5139
Mn | 25 | |
Cu | 29 | |
As | 33 | |
Br | 35 | |
Pm | 61 | |
Tb | 65 |
I have found this article from The American Astronomical Society where they have descovered that the elements that form the supernova are Fe, Na, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Ni, Co, Cu, Y, Zr, Ba, La, Nd and Ce.
In my analyses I have also found Mn and Cu like them. But I have also found As, Br, Pm and Tb that don't match.
