Fast speed!It crosses the galaxy. What's wrong with this star?

Scientists said that LP40-365 fragments will leave the galaxy since then.

A new research report states that a star fragment is passing through the edge of the galaxy at a speed of 2 million miles/h (about 3.2 million kilometers/h).

JJ. Hermes, a professor of astronomy at Boston University, is the co -author of this research. He said in the text: "The speed of this star is too fast, and it will definitely fly away from the Milky Way."

The star named LP 40-365 is about 2000 light years from the earth at the moment.

Calling it as a star may seem a bit generous. In fact, Hermes and his colleagues believe that this star is just a piece of fragment with a super -dense star body. Due to the excessive quality of the companion, the supernova has caused a severe explosion and sprayed this white dwarf during this process.

Odelia Putterman graduated from Boston University and entered Hermes' research after graduation. As a co -researcher, she said in the text: "It is still a very cool and unique thing after experiencing part of the bombing. It is also the only one we found in the time when we start to explore the possibility of such stars. "

This fast -running star was discovered when analyzing data obtained by the US Astronaut Hubble Space Telescope and the satellite of the survey of the transit system. Researchers noticed that the LP 40-365 star not only moved rapidly, but also rotated every nine hours.

For stars, rotation is not surprising. Each star will rotate. Our sun rotates around its central axis every 27 earth days. However, according to researchers, for objects that have experienced supernova explosions, the nine -hour rotation cycle is relatively slow.

This slow rotation cycle shows that LP 40-365 was part of the dual star system, and this pair of star systems have bad "eating habits" at the same time.

According to researchers, in the dual star system, stars generally run around each other, including high -density white dwarfs. In this system, if one of the white dwarfs conveys too much quality to the other party, then the other party may develop into a supernova, the largest energy -scale explosion in space.

It is difficult to confirm that the star is a "dedicor", and that one is a "editor". The object is a space fragment produced by a star explosion. The article wrote that when the two stars rotated at a high speed at the neighboring distance, the supernova produced may bounce other stars at an amazing speed. However, we can only capture LP 40-365 fragments now.

Putterman said: This article provides us with another level of knowledge, that is, when the supernova appears, what other stars will play and what will happen when the supernova explodes. By understanding the experience of this special star, we can gradually understand what other similar stars will happen when facing the same situation.

Due to metal -rich metals, these supernovas survivors have become more interesting. It is not like our sun, mainly composed of hydrogen and 氦. (Astronomers believe that it may be any metal element than hydrogen and weight.)

Hermes said: "There are many strange stars in space. What we see now is only by-products generated by the severe nuclear reaction formed during the star explosion." Therefore, stars like LP 40-365 are very attractive research objects Researchers said.

LP 40-365 is a low-quality white dwarf that moves high-speed in the Milky Way. The element of this white dwarf is extremely rare to lack hydrogen, crickets or carbon. The LP 40-365 may be formed by the IAX-type light supernova. IAX supernova can be regarded as the IA supernova that failed to destroy the entire white dwarf. The "LP" in Benbai Dwarf number is the Rutan -Paloma self -trick compiled by the 1960s.

The galaxy is composed of stars, stars, stars, interstellar gases, dust, and dark matter, and is bound by gravitational binding. The word Galaxy is derived from Galaxias, Greece, which literally means "Milky Way". The size of the galaxy from a dwarf system with only hundreds of millions of stars to a huge galaxy with a somato -star, all running around its quality center. The galaxy is the galaxy where the solar system, including the earth. The galaxy outside the galaxy is collectively known as the river galaxy.
