In the Galaxy there may exist a myriad of freely wandering objects like interstellar Omwamwi, and they may be centers of new planets near other stars.
At the end of 2017, the astronomers noticed an interstellar object passing through our Solar system. 1I/Omwamwi was the first and only example of such a body. However, the astronomer from Germany Falcner Susanne (Susanne Pfalzner) and its British counterpart, Michelle Bannister (Bannister Michele) believe that such strangers may be much more. However, they still remain unnoticed due to their small size and dark surfaces; Omwamwi we were lucky, writes the online edition of the Chronicle.info with reference to naked-science.ru.
However, if the objects in the set are transferred between star systems, then the young star, still surrounded by a protoplanetary disk of gas and dust, they can serve as ready-made “embryos” of young planets, accelerating their growth. This hypothesis Falcner and Bannister Express in an article accepted for publication in the journal the Astrophysical Journal Letters. You can read it in an open online library of arXiv preprints.
Scientists suggest that during the formation of planetesimals when the orbit of their movement has not yet stabilized, due to all sorts of collisions and gravitational interactions of these bodies may be released away from the parent star. Many small nuclei of the planets fill the galaxy and end up in new solar systems. If here the formation of planets is just beginning, the appearance of numerous bodies, such Omwamwi may speed up this process.
Directly of the birth of our Earth from this “interstellar embryo,” scientists never say. However, this possibility is implied of them described the picture. “Some of the planets may contain “Omwamwi” in its center, said Michelle Bannister in an interview for The New Scientist. To follow them is impossible, but the idea is still amazing.”
