Insights into the Production of 44Ti and Nickel Isotopes in Core-collapse Supernovae

The Astrophysical Journal
We report nucleosynthetic results for both ^44 Ti and nickel isotopes for 18 three-dimensional (3D) core-collapse supernova (CCSN) simulations extended to ∼20 s after bounce.

On Rapidly Rotating Magnetic Core-Collapse Supernovae [PDF]

, 2004
The authors have analyzed magnetic effects which may occur in rapidly rotating core collapse supernovae. They consider effects from both magnetic turbulence and the formation of magnetic bubbles.

Constraining the Pulsar 3D Velocity Distribution: The Impact of Spin–Velocity Alignment

The Astrophysical Journal
Quantifying the natal kick distribution of pulsars is essential for understanding supernova physics and binary evolution, yet measurements are historically limited by the lack of radial velocity data.

SN 2021foa: The “Flip-flop” Type IIn/Ibn Supernova

The Astrophysical Journal
We present a comprehensive analysis of the photometric and spectroscopic evolution of SN 2021foa, unique among the class of transitional supernovae for repeatedly changing its spectroscopic appearance from hydrogen-to-helium-to-hydrogen dominated (IIn-to-

The Caltech Core-Collapse Project (CCCP) [PDF]

, 2005
The cosmological utility of type Ia Supernovae prompted numerous studies of these events, and they are now well characterized observationally, both as individual objects and as a population. In contrast, all other types of supernovae (i.e.

Understanding Core-Collapse Supernovae

, 2004
I summarize, in the form of an extended abstract, the ongoing efforts at the University of Arizona (and in collaboration) to understand core-collapse supernovae theoretically. Included are short discussions of 1D (SESAME) and 2D (VULCAN/2D) codes and results, as well as discussions of the possible role of rotation.
