Simulations of stripped core-collapse supernovae in close binaries [PDF]
, 2015 We perform smoothed-particle hydrodynamical simulations of the explosion of a helium star in a close binary system, and study the effects of the explosion on the companion star as well as the effect of the presence of the companion on the supernova ...

Examining Neutrino–Matter Interactions in the Cassiopeia A Supernova
The Astrophysical Journal, 2023 Neutrino interactions with stellar material are widely believed to be fundamental to the explosion of massive stars. However, this important process has remained difficult to confirm observationally.

Footprints of the Newly-Discovered Vela Supernova in Antarctic Ice Cores?
, 1999 The recently-discovered, nearby young supernova remnant in the southeast corner of the older Vela supernova remnant may have been seen in measurements of nitrate abundances in Antarctic ice cores.

Gamma-ray emission from young supernova remnants: Hadronic or leptonic?
EPJ Web of Conferences, 2016 The debate on the nature of the gamma-ray emission from young supernova remnants is still open. Ascribing such emission to hadronic rather than leptonic processes would provide an evidence for the acceleration of protons and nuclei, and this fact would ...

Magnetohydrodynamic Simulations of the Supernova Remnant G1.9+0.3
The Astrophysical Journal, 2023 The youngest Galactic supernova remnant G1.9+0.3 shows a discrete feature between its radio and X-ray morphologies. The observed radio morphology features a single maximum in the north, while the X-ray observation shows two opposite “ears” on the east ...

Supernova remnant S147 and its associated neutron star(s)
, 2005 The supernova remnant S147 harbors the pulsar PSR J0538+2817 whose characteristic age is more than an order of magnitude greater than the kinematic age of the system (inferred from the angular offset of the pulsar from the geometric center of the ...

Direct Measurement of Neutron-Star Recoil in the Oxygen-Rich Supernova Remnant Puppis A [PDF]
, 2006 A sequence of three Chandra X-ray Observatory High Resolution Camera images taken over a span of five years reveals arc-second-scale displacement of RX J0822-4300, the stellar remnant (presumably a neutron star) near the center of the Puppis A supernova ...

Generation of Cosmic rays in Historical Supernova Remnants
EPJ Web of Conferences, 2013 We present the results of observations of two types of Galactic supernova remnants with the SHALON mirror Cherenkov telescope of Tien-Shan high-mountain Observatory: the shell-type supernova remnants Tycho, Cas A and IC 443; plerions Crab Nebula, 3c58 ...
