Observational constraints on the progenitor of core-collapse supernovae [PDF]

, 2016
It is well-known that some massive stars evolve to an end state which results in the collapse of the stellar core, as the hydrostatic pressure can no longer support gravity, leading to powerful explosions called supernovae (SNe).

Equation of State Effects in Core-Collapse Supernovae [PDF]

Physical Review Letters, 2020
We investigate the impact of different properties of the nuclear equation of state in core-collapse supernovae, with a focus on the proto-neutron-star contraction and its impact on the shock evolution. To this end, we introduce a range of equations of state that vary the nucleon effective mass, incompressibility, symmetry energy, and nuclear saturation

Long gamma-ray bursts and core-collapse supernovae have differentenvironments [PDF]

, 2006
When massive stars exhaust their fuel they collapse andoften produce the extraordinarily bright explosions known ascore-collapse supernovae. On occasion, this stellar collapse also powersan even more brilliant relativistic explosion known as a long ...

Nuclei in core-collapse supernovae engine

Progress in Particle and Nuclear Physics, 2023
Herein, we review the nuclear equations of state (EOSs) %for core-collapse supernova simulations and the constituent nuclei of core-collapse supernovae (CCSNe) and their roles in CCSN simulations. Various nuclei such as deuterons, iron, and extremely neutron-rich nuclei compose in the central engines of CCSNe.

Essential ingredients in core-collapse supernovae

AIP Advances, 2014
Carrying 1044 joules of kinetic energy and a rich mix of newly synthesized atomic nuclei, core-collapse supernovae are the preeminent foundries of the nuclear species which make up our solar system and ourselves.

The Progenitor of the S147 Supernova Remnant

The Astrophysical Journal
The supernova remnant (SNR) S147 contains the pulsar PSR J0538+2817 and a likely unbound binary companion, HD 37424. It is the only good Galactic candidate for a binary unbound by a core-collapse supernova.

Proprioception drives tension wood formation for autotropic straightening and postural control in trees

New Phytologist, EarlyView.
Proprioception controls trunk straightness in trees through opposite tension wood formation. A spherical growth chamber (a), combined with a two‐dimensional rotating clinostat (b2), suppresses gravi‐ and phototropic sensing. The tree is first tilted horizontally (b1), triggering upward gravitropic bending, actuated by tension wood formation on the ...

Production of Radioactive 22Na in Core-collapse Supernovae: The Ne-E(L) Component in Presolar Grains and Its Possible Consequences on Supernova Observations

The Astrophysical Journal
Presolar graphite grains carry the isotopic signatures of their parent stars. A significant fraction of presolar graphites show isotopic abundance anomalies relative to solar for elements such as O, Si, Mg, and Ca, which are compatible with ...
