In the next encounter with the black hole, a mysterious object that survived is revealed

A mysterious cloud that somehow survived the collision with the magnificent black hole has now been unveiled.

According to a new study of matter G2, these are actually three small stars, a cloud of gas and dust born from them. This explanation offers a very well-organized solution to the unanswered questions since the return of Sgr A * from G2 in 2014 – a supermassive black hole in the center of the galaxy.

“We suggest that the dust – covered objects observed are the remains of a young star cluster formed on a nuclear disk.” The researchers wrote in their article,

G2 Discovered in 2011 (described in the study) Published in 2012) At that time jumped into a phenomenon called the perinigricone – in its orbit it is closest to the black hole.

The astronomers fully expected that the next collision would cause G2 to disintegrate, change its path to SGR A *, and create some massive black holes.

The fact that nothing happened later was called “.Cosmic FidgetG2 stretched out as it approached the black hole; After perinigricone, it returned to a more compact size.

Another annoying feature of the G2 is that it is much hotter and much hotter than dust. Sgr A * or other stars may have heated the object, but the temperature will remain the same wherever it is. Anything heated by G2 came from inside the cloud, indicating no external influences.

Both of these properties, astronomers have found, are more consistent with the nature of the star. Last year, a team of researchers suggested that the G2 cloud obscured a hidden star – a large cloud of gas and dust that formed around them as a result of the collision of the two stars.

But the same study revealed the discovery of four other similar objects at the center of the galaxy, increasing the total number of G objects to six. It’s a lot of merged binaries.

Now, a team of researchers led by Florian Peasker, an astronomer at the University of Cologne in Germany, has come up with an alternative explanation after a detailed review of 14 years of observation using a very large telescope. Symphony Machine.

According to their analysis, G2 should obscure three stars that are 1 million years old. He is younger than the stars; In contrast, the Sun is 4.6 billion years old. G2 stars are so small that they are still surrounded by objects from the cloud that formed them.

“That G2 actually consists of three growing young stars, which is sensational.” Says PaiskerThis is because the discovery makes these three stars the youngest star ever observed around SgrA *.

A. already at the Galactic Center Strange population of young stars, Known as s-cluster, Depending on the Peisker team model, G2 stars may be included in this population.

The stars could have come from the same nursery and formed a cluster, which later disintegrated, splitting the individual stars and forming new orbits around Sgr A *.

Although not related to the S cluster, G2 stars were once part of a larger group of stars. Other dust particles orbiting Sgr A * may be members of this galaxy, which may be limited by gravity after moving to a supermassive black hole from a greater distance.

Since the atmosphere around Sgr A * is not considered favorable for star formation, more work will be needed to determine where G2 and other G objects originated. Black holes,

“The new results provide unique insights into how black holes work.” Says Paisker,

“We can use the SgrA * atmosphere as a project to learn more about the evolution and processes of other galaxies in completely different corners of our universe.”
