Classifying core collapse supernova remnants by their morphology as shaped by the last exploding jets

N Soker - Research in Astronomy and Astrophysics, 2023 - iopscience.iop.org
Under the assumption that jets explode all core collapse supernovae (CCSNe), I classify 14
CCSN remnants (CCSNRs) into five groups according to their morphology as shaped by …

Comparing neutron star kicks to supernova remnant asymmetries

T Holland-Ashford, LA Lopez, K Auchettl… - The Astrophysical …, 2017 - iopscience.iop.org
Supernova explosions are inherently asymmetric and can accelerate new-born neutron
stars (NSs) to hundreds of km s− 1. Two prevailing theories to explain NS kicks are ejecta …
