Overview

ℹ️

Kronberger 25 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high extinction. It is catalogued as a metal-rich, young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is well-studied in the literature.

Note: This object shares a small percentage of members with at least one entry reported in the same catalogue. See table with shared members information.

Distant High extinction Metal-rich Young

Palma et al. (2025)
Part of multiple system G134, along with CWNU_2051 and HSC_198.

Morales et al. (2013)
Classified as morphological type 'OC2' (totally exposed cluster without correlation with ATLASGAL emission). Morphological flag: exposed cluster, with submm emission not associated with the cluster.

Cavallo et al. (2024)
Bronze sample.

Almeida et al. (2025)
Mass determination: invalid due to poor quality CMD. Isochrone match: worst fit.
