In this article, the authors show that energy injected into an expanding supernova by a highly magnetic (B � 5 � 10 14 G)neutron starspinning at an initial period of Pi 2 20 m scan substantially brightens the lightcurve.Abstract:

Explosion Mechanisms of Core-Collapse Supernovae
TL;DR: The neutrino-heating mechanism, aided by nonradial flows, drives explosions, albeit low-energy ones, of O-Ne-Mg-core and some Fe-core progenitors as mentioned in this paper.

TL;DR: In this paper, the authors presented the results of the Dark Energy Survey (DES) 2013, 2014, 2015, 2016, 2017, 2018, 2019 and 2019 at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign.

Mass Loss: Its Effect on the Evolution and Fate of High-Mass Stars
TL;DR: For example, the authors showed that mass loss rates for standard metallicity-dependent winds of hot stars are lower by a factor of 2-3 compared with rates adopted in modern stellar evolution codes, due to the influence of clumping on observed diagnostics.

Luminous Supernovae
TL;DR: High-resolution spectroscopy of the supernova PTF 11kx is reported, which was detected on 26 January 2011 by the Palomar Transient Factory survey, and the data suggest a red giant star companion whose material got transferred to the white dwarf.

TL;DR: Observations of a class of luminous supernovae whose properties cannot be explained by any of the following processes: radioactive decay of freshly synthesized elements, explosion shock in the envelope of a supergiant star, and interaction between the debris and slowly moving, hydrogen-rich circumstellar material.

Interaction of a Pulsar Wind with the Expanding Supernova Remnant
TL;DR: In this article, the authors study the interaction of a pulsar wind with the uniformly expanding supernova remnant by means of numerical simulation and find three independent instabilities in the interaction region between the pulsars wind and the expanding supernovae.
