[en] The genetic relationship between supernovae (SNe) and supernova remnants (SNRs) is an important factor in understanding the nature of both phenomena. We present here some new results on SNe and SNRs and discuss their implications in the SN-SNR relationship

[en] The possibility that a Rayleigh-Taylor instability may lead to an early fragmentation of a supernova shell is investigated by means of 1-, 2-, and 3-dimensional hydrodynamic simulations. In particular, we consider a point explosion in a n = 3 polytrope, but in contrast to recent simulations with smoothed particle hydrodynamics, we do not find evidence for fragmentation of the shell. These results are in accord with analytic considerations

[en] A Catalogue of Supernovae (SNe) is presented which tabulates the main data relative to all extragalactic SNe discovered up to 1988 December 31, and to their parent galaxies. In total 661 SNe are listed of which 267 are classified. For an easier consultation, two lists are given where the SNe are ordered chronologically and by Right Ascension, respectively. The overall distribution of classified supernovae over the morphological types of their parent galaxies is also presented in a summary table

[en] We present a catalogue of photometric observations (UBV or pg) of 81 supernovae of type I. Only supernovae with multiple data were included

[en] Two examples are given of probable radio jet/supernova remnant associations: G332.4 + 0.1 and G315.8 - 0.0. In both cases the jet length is larger than the radius of the remnant's shell, and the jet diameter is barely resolved and substantially less than the observed shell thickness. The jet luminosity is 5-10% that of the shell. The G332.4 + 0.1 jet terminates in an extended plume whose luminosity is about 50% that of the shell

[en] The radio source G318.9+0.4 has been tentatively identified as a supernova remnant (SNR). Here I report observations at 843 MHz revealing a remarkable network of arcs in the object which exclude it from any of the standard classes of SNRs. The arcs outline an approximately elliptical region enclosing a bright off-centre core component which has several curved extensions. Although the appearance of the arc structures is unprecedented, G318.9+0.4 might belong to a recently proposed class of non-thermal axisymmetric radio sources unrelated to SNRs. Alternatively, the core component may indeed be a SNR, excited by the stellar remnant of the supernova event, with the arc emission arising through jet activity. (author)

[en] New data on well studied Supernovae and their young remnants are used to evaluate the Cosmic Ray production from these objects. It is shown that Supernovae may be the main source of galactic Cosmic Rays and that most Cosmic Ray energy is reached at the end of the remnant's life time

[en] We present that the story behind the supernova remnant RCW 86 might be one of the most wondrous ever told.
