Query: The potential for tidally heated icy and temperate moons around
  exoplanets   Moons of giant planets may represent an alternative to the classical picture
of habitable worlds. They may exist within the circumstellar habitable zone of
a parent star, and through tidal energy dissipation they may also offer
alternative habitable zones, where stellar insolation plays a secondary, or
complementary, role. We investigate the potential extent of stable satellite
orbits around a set of 74 known extrasolar giant planets located beyond 0.6 AU
from their parent stars - where moons should be long-lived with respect to
removal by stellar tides. Approximately 60% of these giant planets can sustain
satellites or moons in bands up to $\sim 0.04$ AU in width. For comparison, the
Galiean satellites extend to $\sim 0.013$ AU. We investigate the stellar
insolation that moons would experience for these exoplanet systems, and the
implications for sublimation loss of volatiles. We find that between 15 and 27%
of {\em all} known exoplanets may be capable of harboring small, icy, moons. In
addition, some 22-28% of all known exoplanets could harbor moons within a
``sublimation zone'', with insolation temperatures between 273 K and 170 K. A
simplified energy balance model is applied to the situation of temperate moons,
maintained by a combination of stellar insolation and tidal heat flow. We
demonstrate that large moons ($>0.1 $M$_{\oplus}$), at orbital radii
commensurate with those of the Galilean satellites, could maintain temperate,
or habitable, surface conditions during episodes of tidal heat dissipation of
the order 1-100 times that currently seen on Io. (Abridged).
