A Core-collapse Supernova Neutrino Parameterization with Enhanced Physical Interpretability

The Astrophysical Journal Supplement Series
We introduce a novel parameterization of supernova neutrino energy spectra with a clear physical motivation. Its central parameter, τ ( t ), quantifies the characteristic thermal-diffusion area during the explosion.

Observations of supernova remnants with the Sardinia Radio Telescope [PDF]

, 2016
In the frame of the Astronomical Validation activities for the 64m Sardinia Radio Telescope, we performed 5-22 GHz imaging observations of the complex-morphology supernova remnants (SNRs) W44 and IC443.

NEUTRINO CAPTURE INDUCED SUPERNOVA EXPLOSIONS

, 2010
Motivated by the success of kinetic theory in the description of observables in intermediate and high energy heavy-ion collisions, we use kinetic theory to model the dynamics of core collapse supernovae. The specific way that we employ kinetic theory to

Magnetic Reconnection Detonation in Supernova Remnants

, 2018
Expansion of supernova remnants (SNRs) is a key process that refreshes the interstellar medium (ISM) in which a new generation of stars is born. The dynamics and radiative properties of the SNR expansion front not only reflect the physical environment of

Do Type Ia Supernovae Explode inside Planetary Nebulae?

The Astrophysical Journal
The nature of Type Ia supernova (SN Ia) explosions remains an open issue, with several contending progenitor scenarios actively being considered. One such scenario involves an SN Ia explosion inside a planetary nebula (PN) in the aftermath of a stellar ...

A Necessary Condition for the Submergence of Proto–Neutron Star Magnetic Fields by Supernova Fallback

The Astrophysical Journal
Central compact objects (CCOs) are a subclass of neutron stars (NSs) with a dipole magnetic field strength considerably weaker than those of radio pulsars and magnetars.

Phase-transition-induced Collapse of Proto-compact Stars and Its Implication for Supernova Explosions

The Astrophysical Journal
A hadron–quark phase transition (PT) may trigger supernova explosions during stellar core collapse. However, both success and failure have occurred in previous attempts to explode dying stars via this mechanism.

Simulated 3D 56Ni Distributions of Type IIp Supernovae

The Astrophysical Journal
We present the first three-dimensional study of the asymptotic ejecta distributions for a suite of theoretical Type IIp supernovae originating from red supergiant (RSG) progenitors.
