Two new young open clusters discovered

Two new open clusters have been found by analyzing the data from the Gaia satellite. There are two new clusters located in a group of open clusters. There is a paper on arXiv.org.

A group of stars are bound to each other by a giant cloud of atoms. More than a thousand of them have been found in the Milky Way, and scientists are still looking for more. Our understanding of the formation and evolution of our galaxy could be improved if we expanded the list of known open clusters.

At a distance of 5,900 light years, there is a young, large, and rich OC with at least two core. The cluster is part of the primordial group of OCs, a star-forming complex containing several young OCs.

In order to shed more light on the properties of this primordial group of OCs, a team of astronomer led by Juan Casado of the University of Barcelona analyzed the data from the Data Release 3. Two new OCs were discovered as a result of this study.

The initial goal of the present work was to revisit the primordial group of NGC 6871 in order to get a better characterization of this star formation complex. Two new OCs have been identified by the researchers while doing so.

There are two new OCs that are 6,200 light years away. They had a radial velocities of -23 km/s. Casado-Hendy 1 has a 9 and 8.1 arcs.

Casado-Hendy 1 is about 300,000 years younger than Casado- 82. Casado-Hendy 1 had a total mass of 86 solar mass, which is eight solar mass less than Casado-Hendy 2.

The results show that metal abundances are very similar for the two OCs, at a level of 0.015 and 0.017 for Casado-Hendy 1. The values are close to the sun and suggest that the two clusters are similar.

All of the members of the primordial group that contains Casado-Hendy 1 have been born in the same star formation complex. The results show that the primordial group appears to have dispersed quickly.

The authors of the paper said that the detection of Casado 82 and Casado-Hendy 1 suggests that there may be many more new OCs.

Juan Casado and his team discovered and described two young open clusters in the primordial group. You can find it in thearxiv.2211.12843.
