The Fomalhaut system is very interesting: dust disk around the star, a distant exoplanet and even farther accompanying facilities. Now identified as a new co-star, which appears in the sky 6 degrees away.
The Fomalhaut, aka Alpha Piscis Austrina, a close neighbor of the Sun in the constellation of the Southern Fish, is only 25 light years from us. The star has already served many interesting things: extensive surrounding dust disk, which according to the Hubble images exoplanet orbiting a distant. In addition, a wide double star Fomalhaut also: companion, the star TW PsA signal light 0.9 year orbit it.
LP 876-10 was recently marked with a star on the almost completely unknown, faint red dwarf. That is, until it was not detected under the Sun's neighborhood RECONS research (Research Consortium on Nearby Stars) program that is only 24.8 light-years from the Sun. Though visible in the sky, almost six degrees of Fomalhauttól the sajátmozgásuk almost identical, and it is immediately aroused suspicion for members of Eric's mother (University of Rochester, USA) led the research team.
Six Degrees (twelve full moon) seem very far away, but as each star member of the immediate vicinity of the Sun, this distance is only 2.5 light-years of space. Calculations of Fomalhaut's gravity may outweigh the impact of light-years, the stars, so the LP 876-10 are located well within this, gravitationally bound planet. Highly unlikely on the basis of the researchers estimate that two stars almost accidentally moving at the same speed so close to each other are more likely to have always belonged together.
The discovery is significant because in the vicinity of the Sun's tiny red dwarfs age very accurately known. In the case of Fomalhaut and TW PsA, however, has previously been determined to fall between centrale termice 400 and 480 million years of age, which means that within the system LP 876-10 is such a time. The previously obscure red dwarf stepped forward with this important reference point in describing the development of the smallest dwarf star models.
