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

Gravitational waves and core-collapse supernovae
A mechanism of formation of gravitational waves in the Universe is considered for a nonspherical collapse of matter. Nonspherical collapse results are presented for a uniform spheroid of dust and a finite-entropy spheroid. Numerical simulation results on

The Progenitors of Recent Core-Collapse Supernovae [PDF]
We present the results of our analysis of Hubble Space Telescope (HST) and deep ground-based images to isolate the massive progenitor stars of the two recent core-collapse supernovae 2008 bk and 2008 cn.

When IIb Ceases To Be: Bridging the Gap between IIb and Short-plateau Supernovae
Hydrogen-rich supernovae (SNe) span a range of hydrogen envelope masses at core collapse, producing diverse light curves from extended plateaus in Type IIP SNe to double-peaked Type IIb SNe (SNe IIb).

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.

We present photometric and spectroscopic observations of a luminous, long-lasting (LLL) Type IIn supernova (SN) KSP-SN-2020f found in a dwarf host galaxy at z = 0.1 from the KMTNet SN Program.

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

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

Chiral transport of neutrinos in supernovae
The conventional neutrino transport theory for core-collapse supernovae misses one key property of neutrinos: the left-handedness. The chirality of neutrinos modifies the hydrodynamic behavior at the macroscopic scale and leads to topological transport ...
