Comparison of rotation period, chromospheric emission log RHK, coronal emission log LXLbol, and Li EW of HR 2562 to those of Hyades (red symbols) and Pleiades (blue symbols) open clusters. In panel a (rotation period), the triangle represents the upper limits derived from the projected rotational velocity. In the same panel the continuous and dashed lines are the sequences of slow rotators for Pleiades and Praesepe, respectively (Stauffer et al. 2016). In panels b, c, and d, showing respectively the chromospheric emission, log LXLbol, and lithium equivalent width, circles and squares represent measurements, while upsidedown triangles represent upper limits. Panels e and f show the kinematic parameters of HR 2562 for the two values of RV derived in this paper and from CORAVEL data, compared to those of several young moving groups. In these panels, the red open circle represents the B3 MG, while the dotted and dashed lines show the limits of the young disk as defined by Montes et al. (2001) and the young star box as defined by Zuckerman & Song (2004), respectively.
