Such outbreaks are possible in outer space enriched with gas, or in a binary system of stars, where there is the possibility of overflow of gas from the surface of the star to the «white dwarf» or «neutron star». This process should be characterized by the presence of hydrogen in the spectral analysis. Similar processes are possible for «neutron star».
After the explosion (collapse), around the «neutron stars», also an amount of vacuum is formed, where the gas is sucked in from outer space.
    — Another, more basic physical process in a supernova outbreak is the explosion — the collapse of the «white dwarf», and of stars with medium and large masses. The explosion of the «white dwarf» the stars of medium mass, in the epicenter of the explosion remains a «neutron star». The volume of the vacuum surrounding the «neutron star» is wider than the one around the «white dwarf». Because of the explosion is ejects the mass of the large volume of surrounding space.
This process is consistent with a supernova explosion of the star of the first type, when the ejected shell shoots out to the spectrum, which is not including hydrogen.
The reason for the explosion, the collapse of the «white dwarf» – it’s a valuable uncontrolled fission of transuranic elements, perhaps in excess of spontaneous decay of extra-heavy elements, including those whose existence is possible only in the state of stars. Perhaps the presence of these elements won’t let the probability to decipher the spectrum to occur, all the elements ejected in the explosion, the shell above the new stars of the first type and the range of all elements of the «neutron star». As a result of this explosion the «neutron star», is born. That means exactly the proof of an explosion during the fission of transuranic elements with neutrons.
    — During the explosion of the «white dwarf», a star of large mass, the entire mass of the «white dwarf» is ejected from the explosion site and formed into a deep vacuum in a huge amount — this is the beginning of a chain of physical processes named the «Black Hole».
Supernova outbreaks are what we have considered as two types of nuclear explosions — (flares) and their different combination with each other.
Supernovae of the first type — is the collapse of the «white dwarf» of the stars of medium and large masses.
The explosion occurs as a result of uncontrolled chain reaction of fission of heavy kernels. In this event part or all of the mass is being thrown out of the «white dwarf». The shell ejection is expanding, since the hydrogen in this type of explosion is not involved, then its spectrum is absent. After the maximum, the flash is reduced logarithmically. By the same law the declining power of fission chain reactions occurs. Similar outbreaks of Supernovas are possible, wherever they a star of medium and large masses. The formation of the «neutron star», its radioactivity and the reduction of power of the radioactivity of the logarithmic law confirms that such an explosion exists.
Supernovae of the second type – It’s a flash of thermonuclear synthesis of hydrogen around the «white dwarf» or the «neutron star», at the expense of dynamic processes in the intake gas from outer space into the volume of the vacuum around the «white dwarf» or a «neutron star».
    — This outbreak is the result of second synthesis with the participation of hydrogen, which has grown deep from outer space.
The spectrum contains lines of hydrogen, there’s no large mass ejection from the star.
The mass of the «white dwarf» should increase. After the outbreak a «white dwarf» remains and possible resurgence.
This type of outbreak is possible in areas rich in cosmic gas — hydrogen, in the sleeves of spiral galaxies and in binary star systems, where there is a possibility of exchanging the masses.
Repetition of the outbreaks of the second type is possible at the presence of a supportive environment.
    — All other types of supernova outbreaks consist of different set of processes we examined at the first and second types of outbreaks.

Possible combinations of supernova explosions.

      1. «White Dwarf» => Flash type 2 => «White Dwarf»
      2. «White Dwarf» => outbreak of type 1 => «Neutron Star»  
      3. «White Dwarf» => outbreak of type 2 => «White Dwarf»  => outbreak of type 1 => «Neutron Star»
      4. «White Dwarf» => outbreak of type 1 => «Neutron Star» => outbreak of type 2 => «Neutron Star»
      5. «White Dwarf» => outbreak of type 2 + outbreak of type 1 => «Neutron Star»
      6. «White Dwarf» => outbreak of type 1 + outbreak of type-2 => «Neutron Star»
      7. «White Dwarf» => outbreak of type 2 => «White Dwarf» outbreak of type 2 => … «White Dwarf» outbreak of type 1 => «Neutron Star» outbreak of type 2 => «Neutron Star»…
      8. «White Dwarf» => outbreak of type 1 => «Neutron Star» => outbreak of type 2 => «Neutron Star» => outbreak of type 2 => «Neutron Star»…
For an explanation of each option, we need to understand the physical processes of outbreaks of the 1st and 2nd types.

    — The outbreak of type 1 — a nuclear explosion as a result of uncontrollable price fission of transuranic atoms.
In this case, the rate of fission of kernels depends not only on the mass of fissile material, but also on the efficiency of the neutron flux.
If the mass of fissile material will be above the «critical», the process of fission chain reaction will increase, i.e., the number of fissionable kernels in each subsequent act of division will increase. Therefore, the energy released in each subsequent act of fission will grow.
In this process, one of the main roles played by the density and efficiency of the neutron flux. If at the «over-critical» mass of fissile material and high neutron flux will be big neutron leakage, or their absorption by other non-dividing kernels, the rate of increase in the chain reaction will be low, which will increase the lifetime of the «white dwarf» until the explosion.
If, however, with a little «over the critical mass» of fissile material, the efficiency of the neutron flux is high, the rate of chain reaction and power of the explosion will be higher and the lifetime of the «white dwarf» before a moment of collapse will be lower.
The effectiveness of the neutron flux is influenced by many factors: temperature, density, and mixing processes of substance in the «white dwarf» and others factors. It is possible that the efficiency of the neutron flux varies with time, due to the mixing of materials in the «white dwarf» and because of the changes in other parameters. Therefore, the lifetime of the «white dwarf» before the collapse — outbreak of type 1, may be different. For stars of equal masses, most likely, this time of close to one another by the value, just like in the bowels of stars with similar masses, going through closely related processes.
During the explosion of the «white dwarf», a part of its mass is ejected into space, and the mass of the fissile material is already in the «neutron star» (former «white dwarf »), becomes less «critical». The chain reaction of fission decays.
Moreover, the characterization of the radiation of «neutron stars» is depending on the power of the explosion and mass ejection.

  — The process of second synthesis — flash supernova of type 2
The reason for the flash of a supernova of type 2 is a vacuum around the «white dwarf», or the «neutron star», relatively to the gas that surrounds this region of space.
In the case of the «white dwarf», the vacuum around it is formed by the termination of a thermonuclear synthesis reaction and the cooling of the gas envelope of the «red giant». In order to describe this process accurately we must create a physical and mathematical model of such processes.
In the case of a «neutron star», the vacuum around it is formed by a powerful explosion and the ejection of mass into space. This process occurs more rapidly and with greater speed. Models of the passage of shock waves exist, but in a dilute gas of space, which is space, not yet. Consequently, in this case it is necessary to build physical and mathematical models.
