Overview

ℹ️

FSR 1484 is a moderately populated, 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 near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is poorly studied in the literature.

Relatively close Moderate extinction Near-solar metallicity Intermediate age

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

Cavallo et al. (2024)
Gold sample.

Hunt & Reffert (2024)
Classified as open cluster. CMD classes: 0.99 (50th percentile), true positive? (human-assigned).

Hunt & Reffert (2023)
Classified as open cluster. CMD classes: 0.99 (50th percentile), true positive? (human-assigned).

Hu et al. (2021)
Ellipticities (core, all): e_core=0.1033, e_all=0.0867.
