The “red giants” are an interesting type of huge and bright stars for astronomers. They are considered old even from the cosmic perspective as they have been evolving over a long period of time. Surprisingly, there is only a few of them in the region near the centre of our Galaxy, where an increased presence of younger stars has been revealed instead. A study, proposing a process to explain this anomaly, co-authored by the researchers from the Czech Academy of Sciences, has been published by The Astrophysical Journal.
