Supernova Science with an Advanced Compton Telescope
P. A. Milne, R. A. Kroeger, L. -S. The
Gamma-ray line emission is a direct probe of the nucleosynthesis that occurs in Type Ia supernovae. In this work we describe the wealth of information obtainable from observations…

Galactic Positron Production from Supernovae
P. A. Milne, M. D. Leising, L. -S. The
The energy deposition into the ejecta of type Ia supernovae is dominated at late times by the slowing of positrons produced in the decays of Co. Fits of model-genera…

A New Study of s-Process Nucleosynthesis in Massive Stars
L. -S. The, M. F. El Eid, B. S. Meyer
We present a comprehensive study of s-process nucleosynthesis in 15, 20, 25, and 30 $\msun$ stellar models having solar-like initial composition. The stars are evolved up to igniti…
