Space observations make it possible to distinguish strange phenomena that are sometimes unexplained. During one of these explorations, astronomers from Goddard Space Flight Center from NASA have discovered a strange stellar object similar to a giant agglomeration of stars. Today, scientists are trying to interpret the different behaviors of the luminous cluster.
The observation of the sextuple system was only possible with the Transiting Exoplanet Survey Satellite (TESS), a NASA telescope. Thanks to him, the researchers were able to deduce that the luminous cluster was in fact a set of six strangely connected stars. This feature has therefore made this system one of the rarest ever observed.
The results of the scientists’ interpretations appear in the journal The New York Times. In addition, after some consultation, the observed stellar set was named TYC 7037-89-1 by astronomers.
A fascinating sixfold system
Scientists wanted to better understand how the primary and secondary stars of TYC7037-89-1 have become so similar and gravitationally connected. To do this, the astronomers were interested in the pairs of binary stars A, B and C of the star system.
Sets A and C orbit each other every 1.6 and 1.3 days. Then, the two couples of this interior quadruple system rotate around each other every four years. The two B-pair stars, meanwhile, collectively orbit in the vicinity of the inner systems every 2,000 years.
Besides, the sun is almost as huge, massive and warm than the main stars of each of the three binaries of the observed star system. However, the size and temperature of secondary stars are all approximately as massive as half those of the sun.
A little-known architecture
Since it began searching for exoplanets in the galaxy in 2018, NASA’s TESS has allowed researchers to observe some interesting phenomena. Thus, the first time this set of stars was observed, astronomers noticed that it flared up and went out inexplicably thousands of light years from earth.
This time around, the sextuplet is made up of a triplet of pairs of binary stars, each orbiting around a separate center of mass while remaining gravitationally bound to the other two. The particularity here is at the level of the couples of stars which encircle the galactic center as a single star system.
