Overview
ℹī¸
VDBH 144 is a rich, dense object of high C3 quality. Its parallax locates it at a very large* distance, well below the mid-plane, affected by moderate extinction. It is catalogued as a massive, metal-poor, intermediate-age 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 (~15.24 kpc) differs significantly from the median photometric distance (~9.85 kpc).

Note: This object contains blue stragglers according to at least one source.

Silver sample.

Hunt & Reffert (2024)
Classified as open cluster. CMD class: 0.08 (50th percentile).

Hunt & Reffert (2023)
Classified as open cluster. CMD class: 0.08 (50th percentile).

Perren et al. (2022)
Also known as Andrew-Lindsay 1 and ESO 96-SC04; hosts the planetary nebula PHR 1315-6555. The CMD shows a densely populated main sequence with the TO at G=17.5 and a scattered RC at similar magnitude. Janes 1994 gives 7.6 kpc; Carraro 2005 used a small 0.6' radius and obtained 16.9 kpc and 0.8 Gyr. Our RDP suggests a radius over 1.5'. ASteCA gives 10.1 kpc and ~1 Gyr. Majaess 2014 (10.0Âą0.4 kpc, 0.8Âą3 Gyr) and CG20 (9.6 kpc, 1.4 Gyr) are the closest matches. Fragkou 2019 gives ~12 kpc and 0.66 Gyr, consistent with OC02 and WEBDA.
