Overview

ℹ️

DBSB 43 is a moderately populated, moderately dense object of very high C3 quality. Its parallax locates it at a large distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is poorly studied in the literature.

Distant Moderate extinction Near-solar metallicity Very young

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

Cavallo et al. (2024)
Gold sample.
