Overview

â„šī¸
NGC 2849 is a rich, very dense object of very high C3 quality. Its parallax locates it at a large distance, well above the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, old cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is well-studied in the literature.

Note: This object contains blue stragglers according to at least one source.

Almeida et al. (2025)
Mass determination: invalid due to poor quality CMD. Isochrone match: worst fit.

Cavallo et al. (2024)
Gold sample.

Hunt & Reffert (2024)
Classified as open cluster. CMD classes: 0.99 (50th percentile), true positive (human-assigned).

Ahumada & Lapasset (2007)
All cluster parameters are from (2003RMxAA..39...41A). Only stars up to 2' from the cluster centre were considered. From their colour-colour diagrams, (2004AJ....128.2331K) conclude that stars 4 and 19 must be foreground stars.
