Unified 1-D Simulations of Gamma-Ray Line Emission from Type Ia Supernovae
P. A. Milne, A. L. Hungerford, C. L. Fryer +9
The light curves of Type Ia Supernovae (SN Ia) are powered by gamma-rays emitted by the decay of radioactive elements such as Ni and its decay products. These gamma-rays are…

Radioactivity of the Key Isotope 44Ti in SN 1987A
Yuko Motizuki, Shiomi Kumagai
We investigate radioactivity from the decay sequence of 44Ti in a young supernova remnant SN 1987A. We perform Monte-Carlo simulations of degradation of the nuclear lines to explai…

44Ti radioactivity in young supernova remnants: Cas A and SN 1987A
Yuko Motizuki, Shiomi Kumagai
We investigate radioactivity from the decay sequence of 44Ti in young supernova remnants (SNRs), Cassiopeia A (Cas A) and SN 1987A. It is shown by a linear analysis that ionization…
