Overview

ℹ️

VDBH 37 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by high extinction. It is catalogued as a massive, 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.

Note: This object shares a small percentage of members with a later reported entry. See table with shared members information.

Distant High extinction Massive Near-solar metallicity Intermediate age

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

Cavallo et al. (2024)
Gold sample.
