Abstract:
M dwarfs host most of the exoplanets in the local Milky Way. Some of
these planets, ranging from sub-Earths to super-Jupiters, orbit in
their stars' habitable zones (HZs), although many likely possess
surface environments that preclude habitability. Moreover, exomoons
around these planets could harbor life for long timescales and thus
may also be targets for biosignature surveys. Here we investigate the
potential habitability, stability, and detectability of exomoons
around exoplanets orbiting M dwarfs. We first compile an updated list
of known M-dwarf exoplanet hosts, comprising 109 stars and 205
planets. For each M dwarf, we compute and update precise luminosities
with the Virtual Observatory spectral energy distribution Analyzer and
Gaia DR2 parallaxes to determine inner and outer boundaries of their
HZs. For each planet, we retrieve (or, when necessary, homogeneously
estimate) their masses and radii, calculate the long-term dynamical
stability of hypothetical moons, and identify those planets that can
support habitable moons. We find that 33 exoplanet candidates are
located in the HZs of their host stars and that four of them could
host Moon- to Titan-mass exomoons for timescales longer than the
Hubble time.
