TL;DR: A temporal series of high-resolution optical spectra of the SN Ia PTF 11kx reveals a complex circumstellar environment that provides an unprecedentedly detailed view of the progenitor system.

TL;DR: In this article, a Type Ic supernova lacking spectroscopic signatures of H and He was observed to have a slowly declining light curve (LC) that cannot be powered by 56Ni/56Co radioactivity, the common energy source for Type Ic SNe.
Journal ArticleDOI
Non-equilibrium ionization and radiative transport in an evolving supernova remnant
TL;DR: In this paper, numerical simulations of the evolution of a supernova (SN) remnant expanding into a uniform background medium with density $n_H = 1.0$ cm$^{-3}$ and temperature of $10^4$ K were presented.
Journal ArticleDOI
A new ionization network and radiation transport module in PLUTO
TL;DR: In this paper, a general-purpose time-dependent ionisation network (IN) and a radiation transport (RT) module in the magneto-hydrodynamic (MHD) code PLUTO are introduced.
