Overview

ℹ️

VDBH 131 is a rich, moderately dense object of high C3 quality. Its parallax locates it at a large distance, below the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, old cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is poorly studied in the literature.

Very distant High extinction Massive Near-solar metallicity Old

Cavallo et al. (2024)
