Overview

ℹ️

AH03 J1725 34.4 is a rich, very dense object of high C3 quality. Its parallax locates it at a relatively close^* distance, near the mid-plane, affected by high extinction. It is catalogued as a very young cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 9 years.

(*): The parallax distance estimate (~1.79 kpc) differs significantly from the median photometric distance (~0.29 kpc).

Note: This is likely a unique object, which shares a moderate percentage of members with at least one previously reported entry. See table with shared members information.

Very close High extinction Very young

Morales et al. (2013)
