Are Ti44-Producing Supernovae Exceptional?
L. -S. The, D. D. Clayton, R. Diehl +6
According to standard models supernovae produce radioactive Ti, which should be visible in gamma-rays following decay to Ca for a few centuries. $^{44}Ti production i…

Supernova Reverse Shocks and SiC Growth
E. A. -N. Deneault, D. D. Clayton, A. Heger
We present new mechanisms by which the isotopic compositions of X-type grains of presolar SiC are altered by reverse shocks in Type II supernovae. We address three epochs of revers…

Placing the Sun in Galactic Chemical Evolution: Mainstream SiC Particles
F. X. Timmes, D. D. Clayton
We examine the consequences and implications of the possibility that the best-fit =4/3 line of the silicon isotopic ratios measured in mainstream SiC grains is identical or para…
