An international team of astronomers has conducted a chemical study of 23 stars in the globular cluster NGC 6544 as part of the APOGEE survey. The research, published April 12 on the arXiv pre-print server, delivers essential ...
Using the Very Large Telescope (VLT), astronomers from Chile have performed a chemical analysis of a sample of stars in the globular cluster NGC 6553. Results of this study, available in a paper published March 12 on the ...
Using the MeerKAT radio telescope array, an international team of astronomers has detected eight new millisecond pulsars. The newfound objects are located in six globular clusters. The finding is reported in a paper published ...
An international team of astronomers has performed photometric and spectroscopic observations of a binary star system known as ASASSN-18aan and have found that the object is an unusual cataclysmic variable with a relatively ...
Globular clusters are extremely dense stellar systems, in which stars are packed closely together. They are also typically very old—the globular cluster that is the focus of this study, NGC 6397, is almost as old as the ...
