A group of Chinese astronomers has discovered nine dwarf stars with high lithium content using the country’s largest optical telescope, LAMOST (Large Sky Field).
As reported by Ukrinform, this was reported by Xinhua.
Given that previously only four such stars were known, the discovery is rightfully considered a breakthrough in astronomical research.
According to the results of the study, the lithium content in these stars is four times higher than in the Sun.
The researchers also found that seven of the nine stars detected had a high axis rotation speed – more than 9 km/sec. Three of them undergo a periodic change in luminosity, and one more star is part of a double star. With this in mind, astronomers associate lithium accumulation in these stars with accumulation, that is, the capture of matter from the surrounding space.
LAMOST is China’s largest multipurpose spectroscope for observing large areas of the sky. With its help, astronomers have found the largest black hole of stellar masses and more than 10,000 lithium-enriched giant stars.
As Ukrinform reports, the NASA/ESA Hubble space telescope photographed the lumpy spiral galaxy CGCG 396-2 in the constellation Orion.
