Overview
ℹ️
FSR 0436 is a poorly populated, very 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 moderately 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).
