International Astronomical Union Colloquium, 1989 Abstract.In this review I will concentrate on older remnants, by which I mean those in which radiative cooling is important somewhere and the swept up mass is sufficiently large for the details of the initial explosion not to matter. For such remnants it is the optical emission which is crucial since it allows us to deduce a great deal about the ...

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

Failed supernova remnants [PDF]
Publications of the Astronomical Society of Japan, 2021 Abstract In a failed supernova, partial ejection of the progenitor’s outer envelope can occur due to weakening of the core’s gravity by neutrino emission in the protoneutron star phase. We consider emission when this ejecta sweeps up the circumstellar material, analogous to supernova remnants (SNRs). We focus on failed explosions of blue

The Supernova – Supernova Remnant Connection [PDF]
, 2016 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 ...

Historical Supernovae and Supernova Remnants [PDF]
International Astronomical Union Colloquium, 1996 The oldest historical supernova (SN), recorded by ancient Chinese in 14th Century B.C. on pieces of tortoise shells or bones, is identified with the aid of modern space γ-ray observations. Hard X-rays with energy up to 20 keV were observed from IC 443 by the X-ray satellite Ginga. We infer from these observations the age of IC 443 is ∼ 1000 — 1400 yrs.

Are Supernovae Responsible for the Gamma Ray Spectrum from the Galactic Center?
Acta Polytechnica CTU Proceedings, 2014 We discuss the supernova remnants distribution as a function of the galactic longitude and compare their positions to that of the detected TeV gamma ray sources. A large fraction of these sources either coincide or a close by known supernova remnants. If

Numerical code for fitting radial emission profile of a shell supernova remnant: Application [PDF]
Serbian Astronomical Journal, 2011 We present IDL (Interactive Data Language) codes for fitting a theoretical emission profile of a shell supernova remnant (SNR) to the mean profile of an SNR obtained from radio observations. Two considered theoretical models are: 1) a shell with

Magnetohydrodynamic Simulations of the Supernova Remnant G1.9+0.3
The Astrophysical Journal, 2023 The youngest Galactic supernova remnant G1.9+0.3 shows a discrete feature between its radio and X-ray morphologies. The observed radio morphology features a single maximum in the north, while the X-ray observation shows two opposite “ears” on the east ...
