Overview
ℹī¸
IC 2488 is a very rich, very dense object of very high C3 quality. Its parallax locates it at a relatively close distance, below the mid-plane, affected by low extinction. It is catalogued as a massive, 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. Gold sample.

Cavallo et al. (2024)
Gold sample.

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

Richer et al. (2021)
The expected number of WDs is 22.8, 0 WD candidates found, and 0 WD candidates found in the wide search.

Rain et al. (2021)
This cluster was include in (Dias et al., 2002A&A...389..871D, Cat. B/ocl) however, parameters log(t)=8.200, Av=0.702, [Fe/H]=0.080 were taken from Bossini et al. (2019A&A...623A.108B, Cat. J/A+A/623/A108). Ahumada & Lapasset (2007A&A...463..789A, Cat. J/A+A/463/789) cite star DR2 5306633687113120000=HD 302225 as a blue straggler, the star is a member according to Cantat-Gaudin et al. (2018A&A...618A..93C, Cat. J/A+A18/A93) however, it is located in the turnoff of the cluster and therefore was not included in our catalogue.

Ahumada & Lapasset (2007)
Diagrams in (1987AJ.....94...92P) were also examined. Adopted cluster centre: star 28 in (1987AJ.....94...92P). Star 99=HD 302225(B8) is cited as a blue straggler in (1987AJ.....94...92P), and is a probable cluster member (2003A&A...399..543C).
