Results of the study, published September 10 on the pre-print server, deliver important insights into the structural and astrophysical parameters of this cluster.
NGC 2509 is an intermediate age OC located in the constellation of Puppis. It is a poorly studied cluster and many of its properties are still uncertain or unknown. For instance, some studies report that NGC 2509 is located about 3,000away, while others point to a much larger distance of at least 8,000 light years. The cluster's age estimates are also debated as the results range from 1 to 8 billion years.
"We performed Gaia DR3 astrometric and photometric data-based study of intermediate-age open cluster NGC 2509. We created the catalog of NGC 2509 by considering a 20 arcmin radius circular field from the cluster center," the researchers wrote in the paper.
