Overview
ℹī¸
ESO 332 13 is a rich, very dense object of very high C3 quality. Its parallax locates it at a relatively close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the absorption parameter (see Parameters). It is moderately studied in the literature.

Note: This is likely a unique object, which shares a moderate percentage of members with at least one previously reported entry. See table with shared members information.

Liu et al. (2025)
Classified as primordial binary cluster 138 along with HSC_2849, and of multiple system 45 along with OC_0673, HSC_2849 and NGC_6231.

Palma et al. (2025)
Part of multiple system G44, along with HSC_2849, CWNU_1851 and NGC_6231.

Cavallo et al. (2024)
Gold sample.

Almeida et al. (2025)
Mass determination: intermediate fit. Isochrone match: good fit.
