Supernovae Cribs
Today’s paper explores the galactic homes of superluminous supernovae — some of the brightest explosions in our universe.
The Explosions of Stars Wrapped in Hydrogen
How does hydrogen affect supernovae? A new theory explores inconsistencies between theory and observation.
Magnetars: The Perpetrators of (Nearly) Everything
Extreme transient events are pushing the limits of our standard explosion models, but magnetars may save the day.
CSI: Universe
A supernova goes off. A star has died. Can its partner have anything to do with it?
A New Model for Rapidly-Fading Supernovae
In this paper the authors present simulations of a model to explain rapidly-fading supernovae, a class of transients whose lightcurves decline quickly without substantial radioactive tails. They posits a standard core-collapse explosion of a standard Type Ib/Ic supernova progenitor, but one that produces very little radioactivity and instead exhibits a light curve governed by oxygen recombination.
W49B: A Jet-Driven Supernova?
The authors discuss the possibility that the strangely-shaped supernova remnant W49B was created by a core-collapse supernova that formed strong bipolar jets instead of a spherical shockwave.
