Overview

ℹ️

Ruprecht 144 is a rich, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, near 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 age and metallicity parameters (see Parameters). It is well-studied in the literature.

Relatively close Moderate extinction Near-solar metallicity Young

Morales et al. (2013)
Classified as morphological type 'OC2' (totally exposed cluster without correlation with ATLASGAL emission). Morphological flag: exposed cluster, without submm emission.

Cavallo et al. (2024)
Gold sample.

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