The American researchers from the laboratory of Lorensa in Berkeley created the new method of determination of svetimosti of sverkhnovykh type Ia. Comparison of visible star size and svetimosti allows easily to determine distance to the object. Within the framework of work scientists searched spectrum features radiations which would correlate with svetimost’yu of object. For this purpose they took advantage of given at 58 sverkhnovykh type Ia, collected within the framework of the program Nearby Supernova Factory.v result they succeeded to set that correlation
streams for frequencies of spectrum of 642 nanometra and 443 nanometra well befits on this role. This correlation allows to calculate svetimost’ sverkhnovoy with an error only in six percents. The results scientists checked up on information about sverkhnovykh type Ia, also got
within the framework of the program Nearby Supernova Factory and in previous researches. About it reported in a press-release, published on the site of laboratory,
amendments will help to reduce statistical error in most researches conducted now. Researchers mark thus, that the physical mechanisms of intercommunication of relation of streams and svetimosti are unknown them – a new law carries cleanly empiric
character.In obedience to modern presentations, sverkhnovye type Ia arise up as a result of explosion of white hop-o’-my-thumbs in the double systems. Hop-o’-my-thumbs are the last of peat-time of evolution of stars by mass less 9-10 sun.In the system a white hop-o’-my-thumb is by gravity one
fields "steals" matter at zvezdy-kompan’ona. When mass of hop-o’-my-thumb almost arrives at the so urgent limit of Chandrasekara, equal the 1,4 sun masses, then into him thermonuclear reactions are started and there is a powerful explosion which is observed from Earth as
sverkhnovaya. Remains sverkhnovoy. Illustration NASA/ESA/JHU
