Overview
ℹ️
Berkeley 60 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, below 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 age, metallicity, and mass parameters (see Parameters). It is very well-studied in the literature.

Note: This object shares a very small percentage of members with a later reported entry. See table with shared members information.

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

Cavallo et al. (2024)
Gold sample.

Hunt & Reffert (2024)
Classified as open cluster. CMD class: 0.92 (50th percentile).

Hunt & Reffert (2023)
Classified as open cluster. CMD class: 0.92 (50th percentile).

Hu et al. (2021)
Ellipticities (core, all): e_core=0.0466, e_all=0.1313.

Ahumada & Lapasset (2007)
Only straggler candidates inside a radius of 2' around the centre of coordinates have been considered.
