Project summary

Grandiose natural phenomena - explosions of supernovae (SNe) have attracted attention of astronomers and astrophysicists for a long time. It is explained by the fact that investigations of SNe and of their remnants (SNRs) are connected with such fundamental problems as structure and evolution of stars, occurrence of neutron stars (pulsars) and black holes at final stages of life of stars, nuclear synthesis, origin of cosmic rays, physics and chemistry of interstellar medium, emission of neutrino and gravitational waves. The most advanced achievements in such areas of research as high temperature phenomena, nuclear processes and physics of elementary particles are invoked for explanation of SN phenomenon.

The aim of the Project is to study the early stages of evolution of supernova and of its remnant, time behavior of supernova electromagnetic emission, the radio emission spectrum evolution of young supernova remnant.

It is supposed to carry out investigations in the following directions:

- modeling types I, II supernova explosion and electromagnetic emission outburst;
- numerical hydrodynamic calculations of supernova shell expansion and of its interaction with inhomogeneous interstellar medium and interstellar magnetic field;
- investigations of charged particle acceleration, amplification of the intrinsic magnetic field and compression of the interstellar magnetic field at different stages of the evolution of supernova remnants;
- radioastronomical observations of young supernova remnants;
- the interpretation of the results of the long-term observations of radio emission of young supernova remnants particularly data obtained by the Project participants during the last 45 years;
- theoretical investigations of electromagnetic emission spectra of shell and plerion supernova remnants and the evolution of these spectra.

As a result of the Project realization the following topics will be investigated:

- mechanisms of SN explosion and statistical properties of distribution of products of an explosion;
- spectra and evolution of spectra of electromagnetic (first of all, synchrotron) emission from SN and SNR;
- time variations of radio emission flux densities of the most powerful SNRs;
- new possibilities of interpretation of all observed electromagnetic emission spectrum of SNe and SNRs by unified model.

Mathematics modeling of the processes accompanying SN explosion and expansion of its shell will be fulfilled on the basis of an adaptation of the interactive system of image processing and the software worked up at RFNC-VNIIEF and showed a good performance in studying the dispersion of matter under the action of powerful pulses of penetrating radiation.

The uniting of efforts of nuclear physicists of RFNC-VNIIEF and of radioastro-nomers of NIRFI seems to be very perspective for solution of problems of the project proposed. Considerable contribution could be made by foreign partners concerned with observations of SNs and of SNRs in different ranges of electromagnetic emission spectrum and also by astrophysicists concerned with development of theoretical conceptions of nature of supernova explosions and of evolution of their remnants.
