arXiv:1512.02652 [pdf, other] A new submm source within a few arcseconds of $α$ Centauri: ALMA discovers the most distant object of the solar system R. Liseau, W. Vlemmings, E. O'Gorman, E.

Subjects: Solar and Stellar Astrophysics (astro-ph.SR) The understanding of the formation of stellar and planetary systems requires the understanding of the structure and dynamics of their outmost regions, where large bodies are not expected to form. Serendipitous searches for Sedna-like objects allows the observation of regions that are normally not surveyed. The Atacama Large Millimeter/submillimeter Array (ALMA) is particularly sensitive to point sources and it presents currently the only means to detect Sedna-like objects far beyond their perihelia. ALMA observations 10 months apart revealed a new blackbody point source that is apparently comoving with $\alpha$ Cen B. We exclude that source to be a sub-/stellar member of the $\alpha$ Centauri system, but argue that it is either an extreme TNO, a Super-Earth or a very cool brown dwarf in the outer realm of the solar system.
5. ConclusionsWithin ten months between 2014 and 2015, ALMA imaging observations revealed a new source in two of the bands, at 0.74 mm (Band 8 ) and 0.87 mm (Band 7) respectively, whereas the noise was too high in the other bands. Staying within 5.5" of both Cen A and B, this object essentially shared the high propermotion of Cen. With a spectral slope of 2, its submm-SED appears thermal. However, simple arguments convince us that this object cannot be an ordinary star. We argue that the object is most likely part of the solar system, in prograde motion, albeit at a distance too far to be detectable at other wavelengths, viz. anETNO (>>100 AU), a hypothesized Super-Earth (300 AU) or a super-cool brown dwarf (20 000 AU).
Возможно девятую планету возможно Немезиду.
Теперь пошлют МКА к ней, как раз лет 30 ему лететь.
Насколько я перевёл, они обнаружили в Койпере сверхземлю или холодный коричневый карлик?
Наверное, они искали вторую планету у Альфа Cen B ...
Ну вот, Ванга пророчила контакт с внеземной цивилизацией в середине этого века.Теперь пошлют МКА к ней, как раз лет 30 ему лететь.И тут наступит мир, дружба, братство на всей Земле.
