FfFfFfFF 58,120 Posted August 13, 2021 Share Posted August 13, 2021 Using the Gemini Observatory, astronomers have detected 15 new periodic and non-periodic variables in a nearby galaxy known as NGC 247. The finding, reported in a paper published July 29 on the arXiv pre-print repository, could improve our knowledge regarding stellar populations of this galaxy. Variable stars could offer important hints into aspects of stellar evolution. They could also be helpful for better understanding the distance scale of the universe. Investigating variables in galaxies that sample a range of metallicities is of special interest for astronomers as such studies have the potential to yield constraints on stellar structure models. As noted in the paper, eight new variables with blue colors have been identified by Davidge's team. However, they added that in order to discover their nature, spectroscopic and additional photometric studies are required.
