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…
Nuclear Reactions Rates Governing the Nucleosynthesis of Ti44
L. -S. The, D. D. Clayton, L. Jin +1
Large excesses of Ca44 in certain presolar graphite and silicon carbide grains give strong evidence for Ti44 production in supernovae. Furthermore, recent detection of the Ti44 gam…
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…
Galactic Evolution of Silicon Isotopes: Application to Presolar SiC Grains From Meteorites
F. X. Timmes, Donald D. Clayton
We calculate and discuss the chemical evolution of the isotopic silicon abundances in the interstellar medium at distances and times appropriate to the birth of the solar system. T…
