Abstract:
We present the Transiting Exoplanet Survey Satellite (TESS) Habitable
Zone Stars Catalog, a list of 1822 nearby stars with a TESS magnitude
brighter than T=12 and reliable distances from Gaia DR2, around which
the NASA's TESS mission can detect transiting planets, which receive
Earth-like irradiation. For all those stars TESS is sensitive down to
2 Earth radii transiting planets during one transit. For 408 stars
TESS can detect such planets down to 1 Earth-size during one transit.
For 1690 stars, TESS has the sensitivity to detect planets down to
1.6 times Earth-size, a commonly used limit for rocky planets in the
literature, receiving Earth-analog irradiation. We select stars from
the TESS Candidate Target List, based on TESS Input Catalog Version 7.
We update their distances using Gaia Data Release 2, and determine
whether the stars will be observed for long enough during the 2yr
prime mission to probe their Earth-equivalent orbital distance for
transiting planets. We discuss the subset of 227 stars for which TESS
can probe the full extent of the Habitable Zone, the full region
around a star out to about a Mars-equivalent orbit. Observing the TESS
Habitable Zone Catalog Stars will also give us deeper insight into the
occurrence rate of planets, out to Earth-analog irradiation as well as
in the Habitable Zone, especially around cool stars. We present the
stars by decreasing angular separation of the 1 au equivalent distance
to provide insights into which stars to prioritize for ground-based
follow-up observations with upcoming extremely large telescopes.
