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

open access: yes, 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.

High-cadence, early-time observations of core-collapse supernovae from the TESS prime mission [PDF]

open access: yes, 2020
We present observations from the Transiting Exoplanet Survey Satellite (TESS) of twenty bright core-collapse supernovae with peak TESS-band magnitudes $\lesssim18$ mag.

Explosive nucleosynthesis in core-collapse supernovae

open access: yes, 2010
The specific mechanism and astrophysical site for the production of half of the elements heavier than iron via rapid neutron capture (r-process) remains to be found.

Astrophysics with core-collapse supernova gravitational wave signals in the next generation of gravitational wave detectors [PDF]

open access: yes, 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 ...

Managing and mitigating future public health risks: Planetary boundaries, global catastrophic risk, and inclusive wealth

open access: yesRisk Analysis, Volume 45, Issue 7, Page 1607-1631, July 2025.
Abstract There are two separate conceptualizations for assessing existential risks: Planetary Boundaries (PBs) and global catastrophic risks (GCRs). While these concepts are similar in principle, their underpinning literatures tend not to engage with each other.

A Slowly Pulsating Run‐Away B Star at High Galactic Latitude Ejected From a Spiral Arm

open access: yesAstronomische Nachrichten, Volume 346, Issue 5, June 2025.
ABSTRACT We report the discovery of the young B6 V run‐away star LAMOST J083323.18 + 430825.4, 2.5 kpc above the Galactic plane. Its atmospheric parameters and chemical composition are determined from LAMOST spectra, indicating normal composition. Effective temperature (Teff$$ {T}_{\mathrm{eff}} $$ = 14,500$$ \mathrm{14,500} $$ K) and gravity (logg ...

Hydrodynamic Mixing of Accretion Disk Outflows in Collapsars: Implications for r-process Signatures

open access: yesThe Astrophysical Journal, 2023
The astrophysical environments capable of triggering heavy-element synthesis via rapid neutron capture (the r -process) remain uncertain. While binary neutron star mergers (NSMs) are known to forge r -process elements, certain rare supernovae (SNe) have ...

Can We Draw Conclusions on Supernova Shock Wave Propagation Using Short‐Lived Radioactive Isotopes?

open access: yesAstronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT We run a three‐dimensional Galactic chemical evolution (GCE) model to follow the propagation of 53Mn (exclusively produced from type Ia supernovae, SNIa), 60Fe (exclusively produced from core‐collapse supernovae, CCSNe), 182Hf (exclusively produced from intermediate mass stars, IMSs), and 244Pu (exclusively produced from neutron star mergers ...

Including Neutrino-driven Convection in the Force Explosion Condition to Predict Explodability of Multidimensional Core-collapse Supernovae (FEC+)

open access: yesThe Astrophysical Journal
Most massive stars end their lives with core collapse. However, it is not clear which explode as a core-collapse supernova (CCSN), leaving behind a neutron star, and which collapse to a black hole, aborting the explosion.
