Overview

ℹ️

UBC 513 is a poorly populated, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the absorption, age, and metallicity parameters (see Parameters). It is moderately studied in the literature.

Relatively close Moderate extinction Near-solar metallicity Intermediate age
