Query: The effect of planet-planet scattering on the survival of exomoons   Compared to the giant planets in the solar system, exoplanets have many
remarkable properties such as the prevalence of giant planets on eccentric
orbits and the presence of hot Jupiters. Planet-planet scattering (PPS) between
giant planets is a possible mechanism in interpreting above and other observed
properties. If the observed giant planet architectures are indeed the outcomes
of PPS, such drastic dynamical process must affect their primordial moon
systems. In this Letter, we discuss the effect of the PPS on the survival of
their regular moons. From the viewpoint of observations, some preliminary
conclusions are drawn from the simulations. 1. PPS is a destructive process to
the moon systems, single planets on eccentric orbits are not the ideal
moon-search targets. 2. If hot Jupiters formed through PPS, their original
moons have little chance to survive. 3. Planets in multiple systems with small
eccentricities are more likely holding their primordial moons. 4. Compared to
the lower-mass planets, the massive ones in multiple systems may not be the
preferred moon-search targets if the system underwent a PPS history.
