Overview

ℹ️

DBSB 100 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by high extinction. It is catalogued as a low-mass, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.84 kpc) differs significantly from the median photometric distance (~3.49 kpc).

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

Distant High extinction Low mass Intermediate age

Morales et al. (2013)
Classified as morphological type 'OC0' (emerging exposed cluster). Morphological flag: possibly associated submm emission surrounding the cluster.
