NGC 1605 is not a Binary Cluster

Research Notes of the AAS, vol. 6, pp. 58

Abstract

Abstract The open star cluster NGC 1605 has recently been reported to in fact consist of two clusters (one intermediate-aged and one old) that merged via a flyby capture. Here we show that Gaia data do not support this scenario. We also report the serendipitous discovery of a new open cluster, Can Batlló 1, with a similar age and distance.
