Cluster aggregates surrounding Pismis 5 in VMR
Listed in IVOA Registry (Virtual Observatory)
In the Gaia era, the precision of astrometric data is unprecedented.
Description
High-quality data make it easier to find more cluster aggregates and support further confirmation of these open clusters. We use Gaia DR3 to redetermine the open clusters surrounding Pismis 5 in the Vela Molecular Ridge.
We also investigate the basic properties of these clusters. We apply two clustering algorithms (StarGO and pyUPMASK) to identify the open cluster members in a five-dimensional space with {alpha}, {deta}, {varpi}, {mu}_{alpha}_cos{delta} and {mu}_{delta}_. We identify eight open clusters surrounding Pismis 5 in the Vela Molecular Ridge.

The open cluster QZ1 is newly discovered. Through investigating the comprehensive properties of the clusters, one open binary cluster candidate (Alessi 43 and Collinder 197) and one triple open cluster candidate (Pismis 5, Pismis 5A, and Pismis 5B) are discussed. Binary and triple open cluster candidates have been identified as potential primordial aggregates based on their similar age, position, and motion.
According to kinematic speculations, the two aggregate candidates will gradually separate, and their interiors will slowly disintegrate.
