The many sides of RCW 86: a type Ia supernova remnant evolving in its progenitor's wind bubble [PDF]
, 2014 We present the results of a detailed investigation of the Galactic supernova remnant RCW 86 using the XMM-Newton X-ray telescope. RCW 86 is the probable remnant of SN 185 A.D, a supernova that likely exploded inside a wind-blown cavity.

A CHANDRASEKHAR MASS PROGENITOR FOR THE TYPE Ia SUPERNOVA REMNANT 3C 397 FROM THE ENHANCED ABUNDANCES OF NICKEL AND MANGANESE [PDF]
, 2015 Despite decades of intense efforts, many fundamental aspects of Type Ia supernovae (SNe Ia) remain elusive. One of the major open questions is whether the mass of an exploding white dwarf (WD) is close to the Chandrasekhar limit.

Supernova 1604, Kepler’s Supernova, and its Remnant [PDF]
, 2017 Supernova 1604 is the last Galactic supernova for which historical records exist. Johannes Kepler's name is attached to it, as he published a detailed account of the observations made by himself and European colleagues.

The fully developed remnant of a neutrino-driven supernova [PDF]
Astronomy & Astrophysics, 2020 Context. The remnants of core-collapse supernovae (SNe) are probes of the physical processes associated with their parent SNe. Aims. Here we aim to explore to which extent the remnant keeps memory of the asymmetries that develop stochastically in the ...

From Supernova to Supernova Remnant: The Three-dimensional Imprint of a Thermonuclear Explosion [PDF]
Astrophysical Journal, 2019 Recent progress in three-dimensional modeling of supernovae (SNe) has shown the importance of asymmetries in the explosion. This calls for a reconsideration of the modeling of the subsequent phase, the supernova remnant (SNR), which has commonly relied ...

A Python Calculator for Supernova Remnant Evolution [PDF]
, 2017 A freely available Python code for modeling supernova remnant (SNR) evolution has been created. This software is intended for two purposes: to understand SNR evolution and to use in modeling observations of SNR for obtaining good estimates of SNR ...

Galactic Supernova Remnant Candidates Discovered by THOR [PDF]
, 2017 Context. There is a considerable deficiency in the number of known supernova remnants (SNRs) in the Galaxy compared to that expected. This deficiency is thought to be caused by a lack of sensitive radio continuum data.

Dust Destruction by the Reverse Shock in the Cassiopeia A Supernova Remnant [PDF]
, 2016 Core collapse supernovae (CCSNe) are important sources of interstellar dust, potentially capable of producing one solar mass of dust in their explosively expelled ejecta.

A solar-type star polluted by calcium-rich supernova ejecta inside the supernova remnant RCW 86 [PDF]
Nature Astronomy, 2017 When a massive star in a binary system explodes as a supernova, its companion star may be polluted with heavy elements from the supernova ejecta. Such pollution has been detected in a handful of post-supernova binaries1, but none of them is associated ...

THE IMPACT OF A SUPERNOVA REMNANT ON FAST RADIO BURSTS [PDF]
, 2016 Fast radio bursts (FRBs) are millisecond bursts of radio radiation whose progenitors, so far, remain mysterious. Nevertheless, the timescales and energetics of these events have lead to many theories associating FRBs with young neutron stars (NSs ...
