Abstract:
Future direct imaging missions similar to the HabEx and LUVOIR mission
concepts aim to catalog and characterize Earth-mass analogs around
nearby stars. The exoplanet yield of these missions will be dependent
on the frequency of Earth-like planets, and potentially the a priori
knowledge of which stars specifically host suitable planetary systems.
Ground- or space-based radial velocity surveys can potentially perform
the pre-selection of targets and assist in the optimization of
observation times, as opposed to an uninformed direct imaging survey.
In this paper, we present our framework for simulating future radial
velocity surveys of nearby stars in support of direct imaging
missions. We generate lists of exposure times, observation time-
series, and radial velocity time-series given a direct imaging target
list. We generate simulated surveys for a proposed set of telescopes
and precise radial velocity spectrographs spanning a set of plausible
global-network architectures that may be considered for
next-generation extremely precise radial velocity surveys. We also
develop figures of merit for observation frequency and planet
detection sensitivity, and compare these across architectures. From
these, we draw conclusions, given our stated assumptions and caveats,
to optimize the yield of future radial velocity surveys supporting
direct imaging missions. We find that all of our considered surveys
obtain sufficient numbers of precise observations to meet the minimum
theoretical white noise detection sensitivity for Earth-mass
habitable-zone planets. While our detection rates and mass-sensitivity
are optimistic, we have margin to explore systematic effects due to
stellar activity and correlated noise in future work.
Description:
Future exoplanet direct imaging NASA mission concept studies have
produced prioritized target lists of nearby, bright stars. All stars
on the green lists must satisfy the criteria that planets in the HZ
would be visible to future direct imaging efforts, and the host stars
themselves are amenable to extreme precision radial velocity (EPRV)
observations; Spectral types=F7-K9, vsini<5km/s.
