Astronomers study the star group NGC 2506, how does the galaxy form and evolve?

Science Fiction Network September 14 (Wang Xiuxia) Recently, Indian astronomers used the spacecraft to conduct research on a evacuation star group called NGC 2506, and provided more insights on its nature. The study stated that there were more than 2,000 members of the star group, and the relevant research results were recently published in the Royal Astronomical Association Monthly.

The evacuation star group is a star group formed by a huge molecular cloud, with gravity and restraint. So far, more than 1,000 have been found in the galaxy, and scientists are still looking for more such star groups. Expanding the scope of the known galaxy evacuation star and conducting detailed research is essential for strengthening our understanding and evolution of the Milky Way.

At a distance of about 12,700 light years, the NGC 2506 is a slender evacuation star group at the middle -aged age. Although the celestial writers have conducted a lot of research on this star so far, they still know very little about their star content. Previous observations show that the NGC 2506 shows the characteristics of quality bias, that is, the low -quality star members are more likely to be outside the star group.

In order to learn more about the star group of NGC 2506, the Institute of India and Sciences used ultraviolet imaging telescopes to conduct a multi -wavelength observation of this star group. The study used a machine learning algorithm to determine the 2175 group members of the NGC 2506. In the end, they detected 9 blue loose stars (BSS), 3 yellow loose stars (YSS) and 3 red clustering stars (RC). Among them, the effective temperature of the BSS star is 7750-9750 k, the temperature of the YSS star is between 6500-6750 k, and the temperature of the RC star is 5000-5250 k.

In addition, the researchers also discovered the star of the above stars and evaluated their basic properties. They found that these celestial bodies were white dwarfs, with the mass of 0.2-0.8 solar quality, and the effective temperature was between 13250-31000 K.

According to researchers, the quality transmission in the dual system mechanism may be the reasons for the formation of at least 40%of the BSS and YSS systems in NGC 2506. However, they do not rule out the merger of the three systems.
