How high energy fluxes may affect Rayleigh–Taylor instability growth in young supernova remnants [PDF]
Nature Communications, 2018 Radiation and conduction are generally considered as the main energy transport mechanisms for the evolution of early supernova remnants. Here the authors experimentally show the role of electron heat transfer on the growth of Rayleigh–Taylor instability ...

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 ...

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 ...

X-ray studies of supernova remnants: a different view of supernova explosions. [PDF]
Proc Natl Acad Sci U S A, 2010 The unprecedented spatial and spectral resolutions of Chandra have revolutionized our view of the X-ray emission from supernova remnants. The excellent data sets accumulated on young, ejecta dominated objects like Cas A or Tycho present a unique opportunity to study at the same time the chemical and physical structure of the explosion debris and 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

Supernova remnants: the X-ray perspective [PDF]
Astronomy and Astrophysics Reviews, Vol. 20, 1, (January 2012), 2011 Supernova remnants are beautiful astronomical objects that are also of high scientific interest, because they provide insights into supernova explosion mechanisms, and because they are the likely sources of Galactic cosmic rays. X-ray observations are an important means to study these objects.And in particular the advances made in X-ray imaging ...

Progenitors of Recombining Supernova Remnants [PDF]
The Astrophysical Journal Letters, Volume 750, Issue 1, article
id. L13 (2012), 2012 Usual supernova remnants have either ionizing plasma or plasma in collisional ionization equilibrium, i.e., the ionization temperature is lower than or equal to the electron temperature. However, the existence of recombining supernova remnants, i.e., supernova remnants with the ionization temperature higher than the electron temperature, is recently ...

Observational signatures of particle acceleration in supernova remnants [PDF]
, 2012 We evaluate the current status of supernova remnants as the sources of Galactic cosmic rays. We summarize observations of supernova remnants, covering the whole electromagnetic spectrum and describe what these obser- vations tell us about the acceleration processes by high Mach number shock fronts.

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 ...
