NASA Spacecope “Hubble” conducted observations of a supernova SN 2020FQV supernova, the results of which will help scientists determine which stars are on the versions of the explosion. This is reported in a press release on phys.org.
SN 2020FQV is at a distance of 60 million light years in the Spiral Galaxies of Siamese Gemini (NGC 4567 and NGC 4568), in the constellation of the Virgin. With the Hubble telescope and the TSSS orbital Observatory (Transiting Exoplanet Survey Satellite), scientists managed to get images of the stars remnants almost immediately after the explosion and a few days after the destruction.
“Hubble” gave astronomers the opportunity to trace the evolution of a substance called in detail for the evolution of a substance, just a few hours after the outbreak of supernova. TESS provided images of the system every 30 minutes, starting from several days before the explosion and ending with several weeks after the explosion. Thanks to this, scientists saw what was happening around the star in the previous decade.
Theoretical models and comparison of them with observation results showed that the mass of the blown star is about 14-15 times more than the mass of the Sun. The exact definition of the mass of the star, which turns into a supernova, is crucial for understanding how massive stars live and die.
