Some of the peculiar qualities of our Solar system—the enveloping cloud of comets, dwarf planets in unusual orbits, and, if it really is, a likely planet 9 away from the sun—were associated with the near approach of another starry sky in the infancy of our system threw Luggage helter-skelter.

But is the star of flaybi to knock down planets, comets and asteroids to the side, rearranging the whole planetary system?

Astrologers from the California Institute in Berkeley and at the Stanford Institute I think, actually found the Smoking gun.

Planet, revolving around a young binary star sky, quite possibly, was shocked by the other pair of the sky that are very close approached to the system between 2 and 3 million years back, in a short time subsequently to this, as the planet was formed from the wrapped disk of dust and gas.

If this is confirmed, it reinforces the argument that the nearest Star errors can help sculpt planetary systems and have every chance to qualify whether their planets with measured orbits.

"1 of the mysteries that arise in the study of exoplanets is that we actually see the system in which the planets are shifted, including if they appear in a flat radial disk," said Paul Kalas, associate Professor of astronomy at the Berkeley Institute. "Has the ability to be, the galactic tsunami knocked on these systems and rebuilt everything around them, but we have no evidence. Our note highlights the exceptional observational confirmation of this, actually what time of the data flaybi gentle on 1 of planetary systems in the galaxy."

Astrologers are already looking for a stellar haul in the past of our Solar system, but since it probably happened 4.6 billion years ago, the bulk of the evidence has cooled. The star system, which was studied by astrologers, identified only by the number HD 106906 and located approximately 300 light years from the Earth in the direction of the crux galaxy, is quite young, only within 15 million years.

Kalas and Robert De rose, in the past, Berkeley post-doctoral research fellowship which is considered at present a research fellow of the University Kavli Stanford of particle astrophysics and cosmology outline own conclusions in the article, accepted for print in astronomy magazine and now available online.

Rogue stars

Kalas, who explores the young, resumed intelligent planetary systems, in order to try to understand, actually what happened in the 1st years of our Solar system, primarily aimed at HD 106906 in 2015, subsequently such as was found, in fact that the powerful planets in a rather unusual orbit. The planet, which has the title HD 106906 b, contains a mass within 11 Jupiters, and it revolves around HD 106906—a newly discovered double star-in orbit tilted approximately 21 degrees from the plane of the disk, which has a whole different fabric around the starry sky. Its current location is at least 738 one further from its own starry sky than the Area from the sun, or about 18 one further from its own starry sky than Pluto from the sun.

Kalas used as an image of the planet twins on the telescope Twins in The Chilean Andes, for example, and the galactic Hubble telescope, in order to more carefully look at HD 106906 and noticed, in fact, that the starry sky still has a one-way comet waist. Unnatural orbit of the planet and that precedent, the fact that the dust disk itself to asymmetrical, showed that, in fact something broke young system.

Kalas and his colleagues, covering de Rosa, introduced in fact that the planet was expelled from its own solar system by interaction with another, while yet unseen planet in the system, or a passing star. The Calas and De Rosa now believe, in fact what happened and that, and another: the planet was ejected into an eccentric orbit, when she came unsafe in close proximity to the Central double star, the scenario proposed in 2017 theorist Leticia Rodet and its employees from the Observatory of Grenoble in France. Re-gravity beats from the BLOB quickly would have thrown the planet into interstellar space, but passing starry sky saved the planet, sliding from its orbit on a more benign distance from the BLOB.

Galactic Observatory Gaia gave them the data they needed to test their guesses. Gaia, launched in 2012 by the European galactic Agency, collects clear measurements of distance, position, and movement for the 1.3 billion starry sky in the milky Way galaxy, a catalog of 10,000 one more than Gaia's predecessor, Hipparcos.

The Calas and De Rosa has gathered information about 461 star in that same cluster, actually that HD 106906, and calculated their fortune back in time—turned galactic clock, for example to say—and noticed, in fact another binary star system, probably close quite close 3 million years back in order to change the planetary system.

"What we've actually created here is to find a starry sky that would be able to provide HD 106906 b with an auxiliary gravity blow, 2 blow, so that it becomes long - lived, for example, as a hypothetical planet 9 would be in our Solar system," Kalas said.

They still noticed, actually that the double star was seen on the line of motion, which was in the range of 5 degrees from the disk system, in fact that prepares even more possible, in fact that the conflict had a powerful and long-term impact on HD 106906.

These double blows have all chances to be actual for stabilization of planets, asteroids and comets around the starry sky, - Kalas declared.

"The study of the planetary system HD 106906 is similar to the return back in time, in order to follow the cloud of Oort comets, forming a circle of our young Sun," he said. "Our larger planet's gravitational threw countless comets at large distances. Almost all of them were completely thrown out, becoming interstellar objects ?Oumuamua, but others were influenced by the passing starry sky. This 2 stellar strike has the ability to separate the orbit of the comet from subsequent conflicts with the planets, saving it from the possibility of ejection. This chain of events saved the simplest fabric of the Solar system in the deepest freeze away from the Sun billion years."

Kalas relies, in fact, that future research, these as a refreshed catalog of measurements Gaia, clarify the meaning of the lumen on HD 106906.

"We started with 461 suspects and noticed 2 who were in the space of the crime," he said. "Their clear role will be revealed when we gather more evidence."
