Future direct imaging missions will primarily observe planets that have beenpreviously detected, mostly via the radial velocity (RV) technique, tocharacterize planetary atmospheres. In the meantime, direct imaging maydiscover new planets within existing planetary systems that have bright enoughreflected flux, yet with insufficient signals for other methods to detect.Here, we investigate the parameter space within which planets are unlikely tobe detected by RV in the near future due to precision limitations, but could bediscovered through reflected light with future direct imaging missions. We usethe HD 134987 system as a working example, combine RV and direct imagingdetection limit curves in the same parameter space through various assumptions,and insert a fictitious planet into the system while ensuring it lies betweenthe RV and imaging detection limits. Planet validity tested through dynamicalsimulations and retrieval tests revealed that the planet could indeed bedetected by imaging while remaining hidden from RV surveys. Direct imagingretrieval was carried out using starshade simulations for two mission concepts:the Starshade Rendezvous Probe that could be coupled with the Nancy Grace RomanSpace Telescope, and the Habitable Exoplanet Observatory. This method isapplicable to any other systems and high contrast direct imaging instruments,and could help inform future imaging observations and data analysis on thediscovery of new exoplanets.
