(i, i-z) diagram of Taurus members (left) identified by Esplin & Luhman (2019) and USco members (right) from Miret-Roig et al. (2022a), represented as blue dots. The HST targets are over-plotted as red dots and the VLT targets are orange squares. The Chabrier et al. (2023) isochrones at 3 Myr (Taurus) and 5 and 10 Myr (USco) and 140 pc are represented by green dashed lines and the corresponding masses are indicated on the right vertical axis. The 5 and 10 Myr isochrones for USco overlap almost perfectly and are represented as one. A reddening vector A_V = 3 mag is also represented, and the planetary mass limit of 13 M_Jupis indicated. The new binary candidate identified in Taurus is over-plotted as a black open circle.
