They discover in our galaxy an intrusive chemical composition star "unlike any other in the Milky Way"

A Chinese-Japanese team of researchers managed to record the asterisk of Karro, the Ursa Major constellation, a strange star of a dwarf galaxy satellite of our Milky Way, according to a recent study published in the journal Nature Astronomy.

The star, like a catalog J1124 + 4535Captured for the first time in 2015 by the Lamosto telescope in China and described as likely Several elements are poor, Like magnesium. The new study, based on observations of the Subaru Telescope of Japan's National Astronomical Observatory (NAOJ), confirmed the assumptions of Chinese astronomers and also recorded comparatively high levels of europium, Unique features For our galaxy.

The chemical composition of that solar body is "Different from any other star in our galaxy", Explains the NAOJ statement explaining the results of the investigation.

"This is the first time that a proportion of elements like this one is observed in a star of the Milky Way," he says.

Since the stars are produced from Interstitial gasIn the galaxies, fairly homogeneous fabric, the chemical composition of J 1124 + 4535 indicates that it came from outside the Milky Way. Most likely it comes from One of the dwarf galaxies Closer, absorbed by our scientists conclude.

"J1124 + 4535 discovery may be the beginning of the chemical identification of accumulated stars [por la Vía Láctea] From dwarf spheroidal galaxies, "astronomers hope.
