Abstract:
The search for habitable planets has revealed many planets that can
vary greatly from an Earth analog environment. These include highly
eccentric orbits, giant planets, different bulk densities, relatively
active stars, and evolved stars. This work catalogs all planets found
to reside in the habitable zone (HZ) and provides HZ boundaries, orbit
characterization, and the potential for spectroscopic follow-up
observations. Demographics of the HZ planets are compared with a full
catalog of exoplanets. Extreme planets within the HZ are highlighted,
and how their unique properties may affect their potential
habitability is discussed. Kepler-296 f is the most eccentric
≲2R⊕ planet that spends 100% of its orbit in the HZ. HD106270b
and HD38529c are the most massive planets (~<13MJ) that orbit within
the HZ, and are ideal targets for determining the properties of
potential hosts of HZ exomoons. These planets, along with the others
highlighted, will serve as special edge cases to the Earth-based
scenario, and observations of these targets will help test the
resilience of habitability outside the standard model. The most
promising observational HZ target that is known to transit is GJ414Ab.
Of the transiting, ~<2R⊕ HZ planets, LHS1140b, TRAPPIST-1d, and
K2-3d are the most favorable. Of the nontransiting HZ planets,
HD102365b and 55Cncf are the most promising, and the best
nontransiting candidates that have ≲2R⊕ are GJ667Cc, Wolf1061c,
Ross508b, Teegarden's Star b, and ProximaCenb.
Description:
The full data set of known exoplanets was downloaded from the NASA
Exoplanet Archive using the Application Programming Interface. For
planets that were missing stellar luminosity, luminosity was
calculated using the Stefan-Boltzmann law. When unavailable, the
stellar radius was calculated from the stellar mass and surface
gravity.
