One of the most important things we know about stars is that their lifespans end one day. Every star has a lifetime and when that time is up one of the most violent explosions in space is experiencing; supernova. Supernovas are when stars explode violently, and these explosions release energy on a massive scale. If the energy released causes a bright light to form in space.

The amount of mass that stars have gives information about how they will die. There were two types of supernovae known so far in this regard. first one More than 10 times the mass of the Sun core collapse supernova that occurs when a star runs out of fuel and its core collapses into a black hole or neutron star.

The other is in binary star systems and one of the two stars. Mass 8 times the mass of the Sun supernova in the case of a white dwarf. In such supernovas, the white dwarf constantly steals matter from the other star and eventually explodes.

We are now sure of the existence of a third type: the electron capture supernova

A New Type of Supernova Has Been Discovered 2

A new study published in Nature Astronomy on June 28, 2021 confirms important information by revealing the first example of a type of supernova predicted 40 years ago. Ken’ichi Nomoto of the University of Tokyo in 1980, electron capture supernova

He did studies in which he pointed to a third type of supernova, called . A supernova observed in March 2018

Three years of research on confirmed Nomoto’s prediction.

Supernova 2018zd began to be studied in detail after the first observations in March 2018. Archival images from the Hubble Space Telescope and Spitzer Space Telescope have revealed a faint object likely to be a star before the explosion. Supernova in galaxy NGC2146 about 31 million light years away and is a supernova relatively close to Earth.

In addition to the data sets created with the data obtained from the telescopes, research on electron capture supernova in the past years also played an important role in this work. Researchers consider a possible all of the features likely to be found in an electron capture supernova found it to be present in the newly observed Supernova 2018zd.

The study also solved a millennial mystery:

A New Type of Supernova Has Been Discovered 3

As the calendars showed the year 1054, a supernova occurred in the Milky Way. According to Chinese records, this The supernova was so bright that it lasted 23 days during the day and about two years at night. continued to appear. The resulting remnant was the Crab Nebula.

The Crab Nebula was one of the strongest candidates for an electron capture supernova in years, but uncertainties in the studies prevented it from being considered a definitive conclusion. new result, The event that created the Crab Nebula confirms information that there is an electron capture supernova.
