Catching Element Formation In The Act
Chris L. Fryer, Frank Timmes, Aimee L. Hungerford +216
Gamma-ray astronomy explores the most energetic photons in nature to address some of the most pressing puzzles in contemporary astrophysics. It encompasses a wide range of objects…
The Role of Radioactivities in Astrophysics
Donald Clayton
I present both a history of radioactivity in astrophysics and an introduction to the major applications of radioactive abundances to astronomy.
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…
