Harvard University scientists say the Sun may once have had a binary companion with a similar mass. If the theory is confirmed, the presence of an ancient companion star increases the likelihood that the Oort cloud formed as it is observed and the ninth planet was trapped rather than formed within the solar system.
In a new theory recently published in The Astrophysical Journal Letters, scientists from Harvard University claim that the Sun may once have had a binary companion with a similar mass. If the theory is confirmed, the presence of an ancient companion star increases the likelihood that the Oort cloud formed as it is observed and the ninth planet was trapped rather than formed within the solar system.
Dr. Avi Leib, a professor of science at Harvard, and Amir Siraj, a graduate student at Harvard, hypothesized that the existence of a long-lost binary companion star in the Sun's progenitor cluster—the collection of stars that formed with the Sun from the same dense cloud of molecular gas—could explain the formation of Oort cloud as we observe it today.
The popular theory links the formation of the Oort Cloud with remnants left over from the formation of the Solar System and its neighbors, when objects were scattered by the planets over great distances and some of them were exchanged between stars. But a binary model could be the missing piece of the puzzle, and according to Siraj, scientists shouldn't be surprised. "Previous models had difficulty in deriving the expected relationship between the diffuse disk self and objects in the outer Oort cloud. The binary capture model offers a significant improvement and refinement, and it seems clear in hindsight: most sun-like stars are born with binary companions."
If the Oort cloud is indeed captured with help from an ancient companion star, the implications for our understanding of how the solar system formed will be significant. "Binary systems are much more efficient at capturing objects than single stars," Loeb said. "If the Oort cloud formed as it is observed, it would imply that the Sun actually had a companion with a similar mass that was lost before the Sun left its parent cluster."
Proving that an Ore cloud has been captured would not only redefine the formation of our solar system but could also answer questions about the origin of life on Earth. "It is possible that objects in the outer Oort cloud played important roles in the history of the land, such as perhaps bringing water to the land and causing the extinction of the dinosaurs," Siraj said. "It is important to understand their origin".
The model also has implications for the putative ninth planet, which Love and Siraj assume is not out there alone. "The puzzle is not only about the Oort cloud, but also about extreme objects beyond Neptune, such as the potential ninth planet," Loeb said. "It is not clear where they came from, and our new model predicts that there should be more objects with an orbital alignment similar to the ninth planet."
The Oort Cloud and the proposed location of the ninth planet are so far from the Sun that direct observation and assessment is a challenge for today's researchers. But Mitzpe Vira C. Robin, which will begin operating in early 2021, will confirm or deny the existence of the ninth planet and its source. Siraj is optimistic: "If the Rubin Observatory verifies the existence of the ninth planet, and a captured source, and also finds a population of similarly captured dwarf planets, then the binary model will be favored over the long-assumed history of a single star."
If the sun did have an ancient companion that contributed to the formation of the outer solar system, its absence today raises the question of where it disappeared to. "Passing stars in the progenitor cluster moved the companion away from the Sun through their gravitational influence," Leib said. "But before the loss of the companion, the solar system had already captured its outer envelope of objects, that is, the Oort cloud and the population of the ninth planet and the like." Siraj added: "The sun's long-lost companion could now be anywhere on the Milky Way."

To Mr. "Truth to the truth", you amused me a lot, and you certainly made my minute, if not the whole hour. Indeed, this is how a bright-faced penitent looks when the mask of the "scientific facts of the Zohar" is kicked off his face.
It feels like a Google Translate translation. From the scientist I would expect more professionalism or a language accessible to laymen (not a layman, but I also had trouble understanding).
Enough with this nonsense "in the Torah it is written... in the Sefer Zohar it is written..." In the Torah so much nonsense is written, and blind faith connects any two obviously independent events. Tomorrow there will be a zombie revolution, they will come and tell us "the vision of the dry bones". Tomorrow there will be no zombie revolution, they will come and say the same thing. Come on Khalas.
Response to *I am here* the infidel and the high tide, may your name be blessed.
Your disbelief and pride leaves you as a fool - the matter of perfection for a person lacking - it's highlighting the disadvantage of perfection. That's why you in your stupidity do not see the sign after sign that stands before your eyes and you only see the downside.
That's why I pray that your name will be blessed - and that you will be reborn with humility and wisdom right today and at this very moment and you will see what is in front of your eyes.
I am happy to see that there were already before we already mentioned that everything is already written in the Torah - which was given to us by the Creator of the world - the King of Kings - the Almighty.
Those who really but really will only look for the truth, they will find it with us in Judaism.
This moon of ours is definitely not a sun that has "waned". The Moon is a block of rock that is comparatively somewhat smaller than the Earth, while the Sun (and so is its lost sister) is a giant ball of hydrogen and helium (and other substances) at tremendous temperatures, and is about a million times heavier than the Earth. There is no way that the second will become the first, even if he was involved in the matter by some thwarted "Hashem", who fails to do a proper job the first time.
And besides, relax, this is just a thesis - a proposal for the agenda of some scientists. It must pass any obstacles in order for it to be accepted as an accepted theory for the formation of the solar system, one should not sail through the nonsense of converts because of this.
Sorry for the mistake, I changed the subtitle and didn't close all the corners
"Scientists from Harvard University claim that..." - how about writing in Hebrew?
In the Torah it is written that at the time of the creation of the world, God created the sun and the moon the same size (a lot of Rabbah or Tanhuma on Parashat Beresheet) and then what happened happened and here he made the moon smaller (the back is still small) to make the sun bigger (the back is still growing).
Let them read in the book of Genesis
It's amazing every time. Now a sensational discovery is being made in a scientific way. But if you read the interpretation of the Torah - Rashi, who wrote his words 1000 years ago.
The great lairs were once created, and the brick fell on the top of it and said: I will not allow two kings to use one crown.
And with the stars - by the hand of the little white, the multitude of her soldiers to her mind.
So what is the conclusion? That 1000 years ago they knew things that we only discover today?
The pace of science is very slow.
It is written in the Torah.
"And God made the two great lights"
And then it is written.. "the great light and the small light".
So how did the sun and moon become from two big two?!
(Tract Chulin S:) Rabbi Shimon ben Pazi explains, Yerah said before the Holy One, blessed be He, Lord of the world, is it possible for two kings to use one crown?
told her to go and take care of yourself, etc.
Distinguished scientists, the sun's twin has shrunk at the behest of its creator, the Almighty.
And he is the moon.
Stop looking and wasting money. Everything is written in the Torah.
Back when science thought the world was flat, it was written in the Zohar that it was round...
This does not explain the existence of an Oort cloud
The cloud should have dissipated or continued
into our solar system…
There is still something else there
This "theory", not necessarily with all that goes with it, is known to every child who starts an ultra-orthodox education, at the age of five. Just type in Google: "There are no two kings serving in one crown". (Moon claim)
