Dynamical and observational constraints on satellites in the inner Pluto-Charon system

Abstract It is not known if Pluto has other satellites besides its massive partner Charon. In the past, searches for additional satellites in the Pluto-Charon system have extended from the Solar-tidal stability boundary (≈90 arcsec from Pluto) inward to about 1 arcsec from Pluto. Here we further explore the inner (i.e.,
