Overview

ℹ️

NGC 7296 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is well-studied in the literature.

Relatively close Low extinction Near-solar metallicity Intermediate age

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

Cavallo et al. (2024)
Gold sample.

Hunt & Reffert (2024)
Classified as open cluster. CMD classes: 1.00 (50th percentile), true positive (human-assigned).

Hunt & Reffert (2023)
Classified as open cluster. CMD classes: 1.00 (50th percentile), true positive (human-assigned).

Hu et al. (2021)
Ellipticities (core, all): e_core=0.2082, e_all=0.0543.
