Historical Observations
On November 6, 1572, the appearance of a “guest star” in the sky was noticed in Korea , and two days later in China . The first to discover a star in Europe was probably the abbot of Messina Mavrolik ( lat. Maurolycus ) [2] .
A significant contribution to the study of the supernova was made by Tycho Brahe , who discovered the supernova on November 11, 1572: [3]
One evening, when I, as usual, was examining the sky, the view of which I am so familiar with, I, to my indescribable surprise, saw a bright star of extraordinary magnitude near the zenith in Cassiopeia. Struck by the discovery, I did not know whether to believe my own eyes.
... The new star did not have a tail, it was not surrounded by any nebula, it was in all respects similar to other stars of the first magnitude ... By its brilliance it could only be compared with Venus, when this last one is in the nearest distance from the Earth. Those gifted with good eyesight could distinguish this star in a clear sky during the day, even at noon. At night, under a cloudy sky, when other stars were hiding, a new star remained visible through rather thick clouds.
Tycho Brahe observed a supernova until it disappeared from the sky. Having determined parallax , he concluded that the "new star" is much further than the moon . Multiple measurements of angular distances from a supernova to neighboring stars have shown that the star does not move. Quietly, the only observer regularly assessed the brilliance of a supernova, first comparing it with Jupiter , and then, when the supernova faded, with neighboring stars [2] .
The results of European observations of the star were published by Tycho Brahe in the book Astronomiae instaurate progymnasmata (Essays on New Astronomy) in 1602 [2] .
Similar observations and conclusions were made by the English scientist Thomas Diggs (together with John Dee ) and suggested that the stars do not form the surrounding sphere, but are located throughout the Universe [4] .
Supernova Remnant
In 1952, a source of radio emission was found at the site of the outbreak [5] .
In 1960, a supernova remnant was found in the optical range.
It is believed that the supernova belongs to type Ia [1] , in which a white dwarf explodes, the mass of which exceeds the Chandrasekhar limit . This can happen in a close binary system due to the accretion of companion star matter onto a white dwarf, or due to the merger of two white dwarfs. In 2004, the second component of the system was found, it turned out to be a star of the spectral class G0 or G2, moving at a speed of more than three times the average in the vicinity of the supernova remnant [6] .
