Overview
ℹī¸
NGC 3114 is a very rich, very dense object of very high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by low extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity and mass parameters (see Parameters). It is very well-studied in the literature.

Malhotra et al. (2026)
Lowest/Highest stellar mass in the catalogue with a mass-ratio estimate: 0.45/3.74 Msun

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

Cavallo et al. (2024)
Gold sample.

Hunt & Reffert (2024)
Classified as open cluster. CMD class: 1.00 (50th percentile).

Hunt & Reffert (2023)
Classified as open cluster. CMD class: 1.00 (50th percentile).

Richer et al. (2021)
The expected number of WDs is 38.2, 1 WD candidate found, and 0 WD candidates found in the wide search.

Hu et al. (2021)
Ellipticities (core, all): e_core=0.0758, e_all=0.0951.

Ahumada & Lapasset (2007)
The apparent cluster diameter was taken from (1988A&AS...75..353S). In the ubvy-beta photometric study (1982PASP...94..232S) stars 8 (= 108 WEBDA), 9 (= 23), 14 (= 210), 15 (= 196), 16 (= 25), 18 (= 211), 61 (= 234), and 124 (= 256) are considered to be blue straggler candidates according to their position in the beta-c diagram: five of them show peculiarities. The following spectra and membership probabilities are from (2001AJ....121.2657G): star 23, B3V, 99%; star 33, B2.5V, 96%; star 149, B3III, 81%; star 180, B2Ve, 93%; star 196, B6V, 95%. Star 108, which also appears as a straggler, is not a cluster member (2001AJ....121.2657G).
