Overview
ℹī¸
NGC 6249 is a rich, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is very well-studied in the literature.

Palma et al. (2025)
Part of multiple system G97, along with Theia_1891, HSC_2824 and Harvard_13.

Almeida et al. (2025)
Mass determination: intermediate fit. Isochrone match: good fit. Silver 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 0.71, 0 WD candidates found, and 0 WD candidates found in the wide search.

Morales et al. (2013)
Classified as morphological type 'OC2' (totally exposed cluster without correlation with ATLASGAL emission). Morphological flag: exposed cluster, without submm emission.
