Toomre and E − L_Z diagrams for our wide binary sample, globular clusters (grey squares), and stars from Monty et al. (2020, stars). Globular clusters associated with the Sequoia event are indicated as purple squares (Massari et al. 2019). The curved dashed line in the upper panel denotes a total velocity of 180 km s⁻¹, which divides the halo and thick disk, and yellow and cyan background boxes in the lower panel indicate the dynamical domains of the Sequoia and Gaia-Enceladus, respectively, as defined by Massari et al. (2019). Although the selection criterion for the Sequoia event slightly varies depending on the literature (e.g., Koppelman et al. 2019; Myeong et al. 2019), the WB2 pair shows remarkably similar properties to the Sequoia stars and its globular clusters.
