A new type of explosion has been discovered in space, which we thought was home to huge explosions and supernovas for years. Star explosions, called micronovas, go beyond the ordinary and have extremely small effects.
Space-related research surprises mankind more and more every day. from planets The gigantic space, which hosts countless materials from satellites, galaxies to meteorites, fascinates with its strange events. Indeed, starbursts are among the best examples of these strange events. astronomersadded a new one to the ones discovered while following these extraordinary events.
Star explosions, called supernovae, are defined as the violent explosion of massive stars that run out of energy. Some explosions are caused by the Sun’s brilliance. one hundred million astronomers discovered a new type of explosion: Introducing Micronova!
It can only affect one thousandth of the moon…
The Micronova explosion, which lasted for hours and was highly effective, occurring in only a small portion of the star, occurred on a type of zombie star known as a white dwarf. 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 behavior not only in explosions but also in many space movements, are destroyed by an explosion called ‘micronova’.
The explosion caused a massive gravitational pull from the nearby star, with one of the white dwarfs acting almost like a vacuum. hydrogen It happens with the start of sucking. After the entire surface of the white dwarf is covered with hydrogen, the pressure here rises, causing a thermonuclear explosion. The hydrogen that closed the dwarf as a result of the explosion can burn for hours.
Unlike explosions that last for weeks: Micronova lasts 10 hours
However, this is not the newly discovered situation. What astronomers have just discovered is; a white dwarf watching white dwarf systems 10 hours it was so bright. 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 very short and shine from time to time will dim was level. 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.
The Micronova explosion that occurs on the surface of white dwarf stars that are actively slurping material from a close binary companion, according to what has been described, quintillion kilograms star material is burning. This amount is several billion of the Great Pyramid of Giza It is said to be equivalent to burning.
