Overview

NGC 3293 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 low extinction. It is catalogued as a massive, near-solar metallicity, very young cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is very well-studied in the literature.
Relatively close Low extinction Massive Near-solar metallicity Very young

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

Cavallo et al. (2024): Gold sample.

💡 Note: The parameters are sometimes transformed from their original values to match the format of the columns shown here, see FAQ. The columns DAv, Bfr, BSS correspond to differential extinction, binary fraction, and blue stragglers, respectively. BSS values can be listed as fractions or integers.
(*): indicates that this parameter is assigned more than one value in the corresponding reference.
