Overview

â„šī¸
DBSB 144 is a poorly populated, moderately dense object of high C3 quality. Its parallax locates it at a moderate* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a very 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 poorly studied in the literature.

(*): The parallax distance estimate (~2.29 kpc) differs significantly from the median photometric distance (~5.55 kpc).

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

Morales et al. (2013)
Classified as morphological type 'EC2' (partially embedded cluster). Morphological flag: cluster partially embedded, presence of an IR bubble.

Cavallo et al. (2024)
Gold sample.
