Overview
ℹ️
NGC 2972 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity and mass parameters (see Parameters). It is very well-studied in the literature.

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

Cavallo et al. (2024)
Gold sample.

Hunt & Reffert (2024)
Classified as open cluster. CMD class: 1.00 (50th percentile).

Rain et al. (2021)
This cluster was include in (Dias et al., 2002A&A...389..871D, Cat. B/ocl) however, parameters log(t)=8.642, Av=1.198, [Fe/H]=-0.090 were taken from Bossini et al. (2019A&A...623A.108B, Cat. J/A+A/623/A108). The distance d=1633.3 (dmode+01) of Cantat-Gaudin et al. (2018A&A...618A..93C, Cat. J/A+A18/A93) was use to fit the isochrone.
