Abstract:
The Habitable Worlds Observatory Preliminary Input Catalog (HPIC) is a
list of ∼13,000 nearby bright stars that will be potential targets for
the Habitable Worlds Observatory (HWO) in its search for Earth-sized
planets around Sun-like stars. We construct this target list using the
TESS and Gaia DR3 catalogs and develop an automated pipeline to
compile stellar measurements and derived astrophysical properties for
all stars. We benchmark the stellar properties in the HPIC relative to
those of the manually curated ExEP HWO Precursor Science Stars list
and find that, for the 164 best targets for exo-Earth direct imaging,
our stellar properties are consistent. We demonstrate the utility of
the HPIC by using it as an input for yield calculations to predict the
science output of various mission designs, including those with larger
telescope diameters and those focused on other planet types besides
Earth analogs, such as Jupiter-mass planets. The breadth and
completeness of the HPIC is essential for accurate HWO mission trade
studies, and it will be useful for other exoplanet studies and general
astrophysics studying the population of bright nearby stars.
Description:
No new observation was conducted for this work. Instead, the Habitable
Worlds Observatory Preliminary Input Catalog (HPIC) was built using
the TESS Input Catalog (IV/38, IV/39), Gaia DR2 (I/345), and
Gaia DR3 (I/355, I/357). Objects of interest were selected based on
their distance and their photometry in the T-band (600-1000nm) from
the Transiting Exoplanet Survey Satellite (TESS) and the J-band (1.25um)
from the 2MASS catalog (II/246). Potential contaminants were then
gathered based on their angular separation with the targets using Gaia
DR3 positional data.

update_TIC_gaia2 = Calculated updating TIC (IV/38) value derived from Gaia DR2 (I/345) bolometric correction
calc_from_gaia = Calculated using Gaia bolometric correction
gaia_dr3_flame = Calculated via Gaia FLAME pipeline
McDonald2017 = From McDonald+2017 (J/MNRAS/471/770)
Stock2018 = From Stock+2018 (J/A+A/616/A33) catalog of giant star properties
calc_from_L_and_Teff = Calculated using the Stefan-Boltzmann relation
Note (11): Source of mass as follows:
Mann2019 = Using Mann+2019 ((J/ApJ/871/63) empirical relation
gaia_dr3_flame = Calculated via Gaia FLAME pipeline
TIC = From TESS Input Catalog (IV/38)
TIC_teff_mass_relation = Using empirical relation in Stassun+2019 (IV/38)
gcs_reanalysis = From GCS reanalysis of Casagrande+2011 (J/A+A/530/A138)
