Scientists found in the center of the spherical nebula formed after the first explosion on the ground, the “hot white dwarf”, a star, which is classified as “star-zombie” ..
According to CNN, this supernova, known as “SN 1181”, was recorded in 1181 of our era and became one of the few observed before the invention of the telescope.
In Chinese and Japanese chronicles, it was mentioned as a “guest star”, since it was visible in the sky for a certain period of time.
“Star-zombie”, located at a distance of 7 thousand light years from the ground, is the result of a rare thermonuclear explosion caused by the fusion of two “white dwarfs”.
Researchers using computer modeling traced the evolution of the “supernova” from the moment of the explosion to today. Astronomers found that “SN 1181” is the only well -known example of a supernova type “IAX” in the Milky Way Galaxy. Typically, such supernovae are less bright than their analogues like “Ia”, and after the explosion, the “zombie star” leave behind, which can again be activated after centuries.
