Overview
ℹ️
FSR 0436 is a poorly populated, dense object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and metallicity parameters (see Parameters). It is well-studied in the literature.

Palma et al. (2025)
Part of multiple system G224, along with UBC_398 and OC_0206.

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 class: 0.17 (50th percentile).

Hunt & Reffert (2023)
Classified as open cluster. CMD class: 0.17 (50th percentile).

Bica et al. (2019)
Web updates in DAML02, some were later removed (2003 to 2010).
