KFU researchers study the Supernova

February 25 - An important astronomical event was the observation night of February 23rd. That was when the telescope managed to obtain spectra of the Supernova SN 2014J.

January 21, 2014 - astronomer Steve Fossey (University College London) conducted workshops with students at the University of London Observatory . The weather was bad and cloudy, so instead of the planned practice on astronomy he showed the students how to work with modern astronomical data detector (receiver) mounted on a small 35cm telescope . They took pictures of bright astronomical objects. Fossey and his students noticed a bright star on pictures of the galaxy Messier 82, which had not been recorded on archival images of this galaxy . They carried out observations with the second telescope, checked the discovery and provided information about it to the Central Bureau for Astronomical Telegrams of the International Astronomical Union, which confirmed that they were the first observers of this landmark event. The Supernova was named SN 2014J. It turned out that it is the closest supernova to the Earth discovered in the last 40 years of observations (not taking into account the famous supernova 1987A in the Large Magellanic Cloud) . The distance from Earth is 11.5 million light-years . So this supernova can be observed even through small amateur telescopes .

Two days later, after the discovery of the supernova SN 2014J, on January 23rd , the researcher from the Department of Astronomy and Space Geodesy at Institute of Physics of KFU Eldar Irtuganov and graduate student Alexander Kolbin conducted observation on telescope RTT150 and joined the international program for the study of this object.

Observations in February will allow to monitor the changes which have occurred in the supernova during one month. The study of supernova allows to specify the modern theory of stellar evolution, it also provided the discovery of phenomenon of accelerated expansion of the universe.
