Exploring the planetary-mass population in the Upper Scorpius association
Figure 3: Left: (Z-J, 𝑍) colour-magnitude diagram for all YJ candidates with 𝑍-band detections (grey dots). Blue open squares and triangles are known USco members from Luhman & Mamajek (2012) and Lodieu et a (2018a). The dashed brown line depicts themodel isochrones from Baraffe et al. (2015). Red dots highlight USco member candidates after applying the selection in the (𝑌 − 𝐽, 𝑌) CMD. Orange and black symbols highlight our best L/T transition candidates for future spectroscopic follow. Right: (𝑌 − 𝐽, 𝑍 − 𝐽) colour-colour diagram with the same legend of symbols.
