Overview
ℹī¸
NGC 5749 is a rich, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the absorption and age parameters (see Parameters). It is very well-studied in the literature.

Liu et al. (2025)
Classified as tidal capture (resonant trapping binary) 55 along with CWNU_95.

Palma et al. (2025)
Classified as optical pair P379, along with CWNU_95.

Almeida et al. (2025)
Mass determination: good fit. Isochrone match: good fit.

Cavallo et al. (2024)
