Abstract

The concepts for future exoplanet direct imaging missions plan to employ schedules that allow for observations to be moved during the mission. This creates chances for an observatory to image an exoplanet multiple times and to image exoplanets discovered by other observatories after the mission begins. For example, the HabEx and LUVOIR missions have a partially dynamic schedules, beginning with a series of predetermined observations whose outcome sets the schedule of followup observations. An orbital fit can be created for an exoplanet that has been observed by other observatories, which helps determine when it will be observable again. However, these fits have uncertainties that propagate in time. We show simulations demonstrating how these errors propagate and compare different methods of estimating when a planet will be visible.
