Supernova 2021hiz was discovered on March 30, 2021, in the galaxy IC 3322A (UGC 7513), located in the constellation Virgo. This is a type Ia supernova, known for its characteristic evolution. Using spectrography, astronomers determined its type and the approximate speed of ejection of the star's envelope into the surrounding space - about 12,300 km / s.

Observations and brightness

On April 11, 2021, our observatory took a picture of supernova SN2021hiz, the estimated brightness of which was about 13.2m. Over the next week, the supernova may increase in brightness a little more, after which its luminosity will gradually fade over six months.

Supernova Structure

Type Ia supernovae occur in binary systems consisting of a normal star and a white dwarf. In these systems, the white dwarf can accumulate matter from its companion star, causing the white dwarf to gravitationally collapse after the Chandrasekhar limit is exceeded. This explosive event produces a bright emission that is observed as a supernova.

Distance to the galaxy

IC 3322A is located 46 million light years from Earth. This makes SN2021hiz an important target for observation, as it provides information about the processes occurring in such distant galaxies and their evolution.

Conclusion

Supernova 2021hiz in the galaxy IC 3322A is a bright event that helps astronomers study processes in binary systems and the evolution of stars. Observations of this supernova open new horizons in understanding Type Ia supernovae and their role in the Universe.
