Abstract:
In the search for life in the cosmos, NASA's Transiting Exoplanet
Survey Satellite (TESS) mission has already monitored about 74% of the
sky for transiting extrasolar planets, including potentially habitable
worlds. However, TESS only observed a fraction of the stars long
enough to be able to find planets like Earth. We use the primary
mission data-the first two years of observations-and identify 4239
stars within 210pc that TESS observed long enough to see three
transits of an exoplanet that receives similar irradiation to Earth:
738 of these stars are located within 30pc. We provide reliable
stellar parameters from the TESS Input Catalog that incorporates Gaia
DR2 and also calculate the transit depth and radial velocity
semiamplitude for an Earth-analog planet. Of the 4239 stars in the
Revised TESS HZ Catalog, 9 are known exoplanet hosts-GJ1061, GJ1132,
GJ3512, GJ685, Kepler-42, LHS1815, L98-59, RRCae, and TOI700-around
which TESS could identify additional Earth-like planetary companions.
Thirty-seven additional stars host yet unconfirmed TESS Objects of
Interest: three of these orbit in the habitable-zone TOI203, TOI715,
and TOI2298. For a subset of 614 of the 4239 stars, TESS has observed
the star long enough to be able to observe planets throughout the full
temperate, habitable zone out to the equivalent of Mars orbit. Thus,
the Revised TESS Habitable Zone Catalog provides a tool for observers
to prioritize stars for follow-up observation to discover life in the
cosmos. These stars are the best path toward the discovery of
habitable planets using the TESS mission data.
Description:
The Transiting exoplanets Survey Satellite (TESS) Habitable Zone Star
Catalog initially derived a list of stars where TESS was expected to
be able to detect transiting planets with Earth-analog irradiation
based on expected observation times.
However, TESS only observed a fraction of the stars long enough to be
able to find planets like Earth. We use the primary mission data-the
first two years of observations-and identify 4239 stars within 210pc
that TESS observed long enough to see three transits of an exoplanet
that receives similar irradiation to Earth.
