Effect of positronium on the ${\hat{I}}^3$-ray spectra and energy deposition in Type Ia supernovae

Anirban Dutta, Andrew Fullard, Wolfgang Kerzendorf +5

Type Ia supernovae (SNe Ia) are powered by the radioactive decay of isotopes such as ${}^{56}$Ni and ${}^{56}$Co, making their ${\hat{I}}^3$-ray spectra useful probes of the explosion mechanism…
