A New Mechanism for Gravitational-Wave Emission in Core-Collapse Supernovae [PDF]

, 2006
We present a new theory for the gravitational wave signatures of core-collapse supernovae. Previous studies identified axisymmetric rotating core collapse, core bounce, postbounce convection, and anisotropic neutrino emission as the primary processes and

44Ti and 56Ni in core-collapse supernovae [PDF]

, 2008
We investigate the physical conditions where 44Ti and 56Ni are created in core-collapse supernovae. In this preliminary work we use a series of post-processing network calculations with parametrized expansion profiles that are representative of the wide ...

SN 2024abvb: A Type Icn Supernova in the Outskirts of Its Host Galaxy

The Astrophysical Journal
We present multiband photometric and spectroscopic observations of supernova (SN) 2024abvb, which exhibits early-time prominent photoionized narrow emission lines of C II superposed on a blue continuum.

Supernova Siblings and Spectroscopic Host Galaxy Properties

The Astrophysical Journal
Over the past century, supernova (SN) searches have detected multiple supernovae (SNe) in hundreds of individual galaxies. So-called SN siblings discovered in the same galaxy present an opportunity to constrain the dependence of the properties of SNe on ...

Astrophysics with Gravitational Wave Signals from Core-Collapse Supernovae [PDF]

, 2019
The next generation of gravitational wave detectors will improve the detection prospects for gravitational waves from core-collapse supernovae. The complex astrophysics involved in core-collapse supernovae pose a significant challenge to modeling such ...

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.
