5σ sensitivity limits in terms of detectable effective temperature of a Jupiter-sized planet based on COND models, for the targets ϵ Eri (blue, solid line), Fomalhaut (green, dash-dotted line), and Vega (red, dashed line). Because ϵ Eri is the closest of the three targets at 3.3 pc, it offers sensitivity to the lowest temperatures. Planets even as cold as Jupiter (134 K) can be detected at >80 AU in the system.
