Abstract:
The next generation of space-based observatories will characterize the
atmospheres of low-mass, temperate exoplanets with the direct-imaging
technique. This will be a major step forward in our understanding of
exoplanet diversity and the prevalence of potentially habitable
conditions beyond the Earth.
We compute a list of currently known exoplanets detectable with the
mid-infrared Large Interferometer For Exoplanets (LIFE) in thermal
emission. We also compute the list of known exoplanets accessible to a
notional design of the future Habitable Worlds Observatory (HWO),
observing in reflected starlight.
With a pre-existing statistical methodology, we processed the NASA
Exoplanet Archive and computed orbital realizations for each known
exoplanet. We derived their mass, radius, equilibrium temperature, and
planet-star angular separation. We used the LIFEsim simulator to
compute the integration time (tint) required to detect each planet
with LIFE. A planet is considered detectable if a broadband
signal-to-noise ratio S/N=7 is achieved over the spectral range
4-18.5um in tint<100h. We tested whether the planet is
accessible to HWO in reflected starlight based on its notional inner
and outer working angles, and minimum planet-to-star contrast.
LIFE's reference configuration (four 2-m telescopes with 5% throughput
and a nulling baseline between 10-100m) can detect 212 known
exoplanets within 20 pc. Of these, 49 are also accessible to HWO in
reflected starlight, offering a unique opportunity for synergies in
atmospheric characterization. LIFE can also detect 32 known transiting
exoplanets. Furthermore, we find 38 LIFE-detectable planets orbiting
in the habitable zone, of which 13 have Mp<5M⊕ and eight have
5M⊕<Mp<10M⊕.
LIFE already has enough targets to perform ground-breaking analyses of
low-mass, habitable-zone exoplanets, a fraction of which will also be
accessible to other instruments.
Description:
Catalogue of all the known exoplanets within 20pc produced with our
statistical methodology (see Sect. 2 of the paper). We report, for
each parameter, the median values of the probability distributions
resulting from the 1000 orbital realizations and the uncertainties
given by the 16% and 84% percentiles.
Additional details on the statistical methodology used to produce this
table can be found in Carrion-Gonzalez et al., 2021A&A...651A...7C 2021A&A...651A...7C.
