Position of κ And A in a color–magnitude diagram (CMD) compared to other A and B-type members of the Pleiades, the IC 2391 cluster, Scorpius-Centaurus (ScoCen), Ursa Majoris group, and other young moving groups in the solar neighborhood (see legend). The star’s position in the diagram is consistent with some members of all the plotted samples except the Ursa Majoris moving group (UMa), which is clearly older and more evolved. The placement in the CMD suggests that κ And is not much older than the upper limit of the Pleiades, 150 Myr. The dash-dotted lines are Ekström et al. (2012) tracks that include rotation. These models predict an age of 250 Myr for κ And, but they overestimate the ages of B-type cluster members. The dotted lines are 5th-order polynomial fits to the Pleiades and IC 2391 sequences and are shown to highlight them for clarity.
