Overview

ℹ️

ASCC 93 is a moderately populated, very dense object of low C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, very young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is moderately studied in the literature.

Relatively close Moderate extinction Massive Near-solar metallicity Very young

Morales et al. (2013)
Classified as morphological type 'OC0' (emerging exposed cluster). Morphological flag: one or a few submm emission within the cluster area, but the submm emission is likely associated to the cluster.

Cavallo et al. (2024)
Wood sample.

Hunt & Reffert (2024)
Classified as open cluster. CMD classes: 0.13 (50th percentile), false positive (human-assigned).
