The group of scientists from the different countries of Europe presented description sverkhnovoy, the parameters of which do not allow to attribute it to none of the set types. To sverkhnovym II type stars are added with mass, excelling a 8 sun, which conclude the existence in the most powerful explosive process. In a center an exploding area there is a neutron star or black hole, and parts of external shell fly away
in all parties with speed, sometimes reaching a to 30 000 km/p. At explosions some "weak" sverkhnovykh II type considerably (in a few dozens of one times) less energy is selected, what in a standard process; their svetimost’ changes properly.
However and there are lines of hydrogen in their spectrums of flashes. Scientists report that sverkhnovaya SN 2008ha, opened in November the last year, became the first star such, in the spectrum of which not revealed lines, proper to hydrogen. In order that to explain
non-standard parameters of sverkhnovoy, scientists offered two models. Possibly, the evolution SN 2008ha began as a star of middle mass in the double system and gradually "threw down" external layers in the process of co-operating with the second component of the system. On
to the alternative version, the lack of hydrogen was caused by influence of star wind on the shell of massive star, after the explosion of which a black hole stopped behind. If the last supposition will appear faithful, researchers will be able to link the flashes of similar sverkhnovykh
with long gamma-vspleskami: this connection was predicted in theory, but not confirmed by given supervisions, reports "Komp’yulenta".
