The Supernova -- Supernova Remnant Connection [PDF]
, 2017 Many aspects of the progenitor systems, environments, and explosion dynamics of the various subtypes of supernovae are difficult to investigate at extragalactic distances where they are observed as unresolved sources. Alternatively, young supernova remnants in our own galaxy and in the Large and Small Magellanic Clouds offer opportunities to resolve ...

Supernova Remnants and their Supernovae [PDF]
International Astronomical Union Colloquium, 1988 AbstractObserving supernova remnants provides important clues to the nature of supernova explosions. Conversely, the late stages of stellar evolution and the mechanism of supernova explosions affect supernova remnants through circumstellar matter, stellar remnants, and nucleosynthesis. The elements of supernova classification and the connection between

Supernova 1987A: a Template to Link Supernovae to their Remnants [PDF]
The Astrophysical Journal, 2015 The emission of supernova remnants reflects the properties of both the progenitor supernovae and the surrounding environment. The complex morphology of the remnants, however, hampers the disentanglement of the two contributions. Here we aim at identifying the imprint of SN 1987A on the X-ray emission of its remnant and at constraining the structure of ...

Supernova Remnants as Clues to Their Progenitors [PDF]
, 2017 Supernovae shape the interstellar medium, chemically enrich their host galaxies, and generate powerful interstellar shocks that drive future generations of star formation. The shock produced by a supernova event acts as a type of time machine, probing the mass loss history of the progenitor system back to ages of $\sim$ 10 000 years before the ...

Multifrequency radio observations of a SNR in the LMC: The case of SNR J0527-6549 (DEM l204) [PDF]
Serbian Astronomical Journal, 2010 We present a detailed study and results of new Australia Telescope Compact Array (ATCA) observations of supernova remnant SNR J0527-6549. This Large Magellanic Cloud (LMC) object follows a typical supernova remnant (SNR) horseshoe morphology ...

Particle propagation in clumpy supernova remnants [PDF]
EPJ Web of Conferences, 2019 The presence of dense clumps in the environment where a supernova remnant expands might have a strong impact in shaping the observed hadronic gamma-ray spectrum.

How Tycho Brahe’s recordings in 1572 support SN 1572 as a type I(a) supernova
Frontiers in Astronomy and Space Sciences, 2023 The 450th anniversary of the discovery of the SN 1572 supernova event was celebrated in 2022. A closer look at the historical development of the field of supernova astronomy reveals the scientific importance of Tycho Brahe’s 1572 observations of this ...

A new numerical code for hydrodynamical 3D simulations of supernova remnants [PDF]
Serbian Astronomical Journal, 2019 We develop a 3D hydrodynamical code written in C programming language to study the expansion of supernova remnants (SNRs) in the surrounding medium. It is based on the MUSCL-Hancock finite volume scheme with the HLLC Riemann solver.

Electron–Ion Temperature Ratio in Astrophysical Shocks
The Astrophysical Journal, 2023 Collisionless shock waves in supernova remnants and the solar wind heat electrons less effectively than they heat ions, as is predicted by kinetic simulations.
