With continued improvement in telescope sensitivity and observational
techniques, the search for rocky planets in stellar habitable zones is entering
an exciting era. With so many exoplanetary systems available for follow-up
observations to find potentially habitable planets, one needs to prioritise the
ever-growing list of candidates. We aim to determine which of the known
planetary systems are dynamically capable of hosting rocky planets in their
habitable zones, with the goal of helping to focus future planet search
programs. We perform an extensive suite of numerical simulations to identify
regions in the habitable zones of single Jovian planet systems where Earth mass
planets could maintain stable orbits, specifically focusing on the systems in
the Catalog of Earth-like Exoplanet Survey Targets (CELESTA). We find that
small, Earth-mass planets can maintain stable orbits in cases where the
habitable zone is largely, or partially, unperturbed by a nearby Jovian, and
that mutual gravitational interactions and resonant mechanisms are capable of
producing stable orbits even in habitable zones that are significantly or
completely disrupted by a Jovian. Our results yield a list of 13 single Jovian
planet systems in CELESTA that are not only capable of supporting an Earth-mass
planet on stable orbits in their habitable zone, but for which we are also able
to constrain the orbits of the Earth-mass planet such that the induced radial
velocity signals would be detectable with next generation instruments.Comment: 15 pages, 12 figures, Accepted for publication by MNRA
