Space-related research is surprising mankind more and more every day. The gigantic space, which hosts countless materials from planets to satellites, from galaxies to meteorites, fascinates with its strange events. Indeed, starbursts are among the best examples of these strange events. Astronomers added a new one to those discovered while following these unusual events.
Stellar explosions, called supernovae, are defined as the violent explosion of massive stars that run out of energy. While it is known that some explosions can reach 100 million times the brightness of the Sun, astronomers have discovered a new type of explosion: Here is Micronova!
It can barely affect one-thousandth of the Moon…
Micronova explosion, which takes place in only a small part of the star, lasts for hours and is highly effective, a white dwarf It occurred on a kind of zombie star known as These mines, which are actually the cores of dead stars, can be as heavy as the sun even though they are as small as the Earth.
It was discovered that these cosmic nuclei, which exhibit strange behaviors not only in explosions but also in many space movements, are destroyed by an explosion called ‘micronova’.
The explosion occurs when one of the white dwarfs behaves almost like a vacuum, as a huge gravitational force begins to absorb hydrogen from the nearby star. After the entire surface of the white dwarf is covered with hydrogen, the pressure here rises, causing a thermonuclear explosion. As a result of the explosion, the hydrogen that closes the dwarf can burn for hours.
Unlike explosions that last for weeks: Micronova lasts for 10 hours
But this is not the case newly discovered. What astronomers have just discovered is; was that a white dwarf glowed and dimmed for about 10 hours while watching white dwarf systems. The occasional increased brilliance had not been noticed before. Because it would be necessary to follow only these planets for a long time in order to notice the hourly changes in these minor planets.
While scientists tried to make sense of these events, they did not even take into account the possibility of star explosion. Because the explosions were very short and bright from time to time and dim from time to time. However, after a while, the same situation was discovered in different white dwarfs. Eventually, scientists filled in the gaps like puzzle pieces and realized that these explosions were short bursts of stars. These explosions, of which many details are not yet known, were called micronovas.
A Micronova explosion on the surface of white dwarf stars, which reportedly actively slurries material from a close binary companion, burns quintillions of kilograms of stellar material. This amount is said to be equivalent to the burning of several billion Great Pyramids of Giza.
