Overview

Andrews Lindsay 5 is a rich, very dense object of very high C3 quality. Its parallax locates it at a large* distance, near the mid-plane, affected by very high extinction. It is catalogued as a massive, metal-poor, very young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~5.49 kpc) differs significantly from the median photometric distance (~2.78 kpc).

Relatively close Very high extinction Massive Metal-poor Very young

💡 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.
