Scientists from the astronomical observatory of Cordoba (Argentina) decided to consider the extraordinarily compulsive structure around the cluster of the ball type NGC 288. They believe that the results may affect our understanding of the external areas of this type of cluster.
NGC 288 is a ball type living at a distance of 28,700 light years in the Sculptor’s territory. At the age of 10.6 billion years, it is considered a low-concentrated type, where stars are weakly interconnected. There is a large dense core with a dispersed irregular ring.
Some globular clusters in our galaxy are surrounded by extended stellar structures. Early observations suggested that there were tidal tails in a particular specimen that could be pulled out for 1100 light years from the center. One of the reviews even displayed two main tails, while the others showed only one. The team has now taken up an expanded stellar structure around NGC 288, having reviewed the data in the Pan-STARRS telescope. This helped fix hints of a super-long, lumpy structure of a uniform material.
New data show one extra tidal lumpy formation that is 3.5 times larger than the tidal radius of the cluster. When compared with other samples, this tidal tail displays a moderately extended structure. This suggests that additional reviews of external areas will be needed, which will help to find a link between tides, stellar populations and dynamic stories, or the lack thereof.
