Overview
ℹī¸
Czernik 41 is a very 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 massive, near-solar metallicity, young cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is moderately studied in the literature.

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

Cavallo et al. (2024)
Bronze sample.

Hunt & Reffert (2024)
Classified as open cluster. CMD class: 0.21 (50th percentile).

Hunt & Reffert (2023)
Classified as open cluster. CMD class: 0.21 (50th percentile).

Hu et al. (2021)
Ellipticities (core, all): e_core=0.2604, e_all=0.0969.
