Using a large suite of n-body simulations, we explore the discovery space for new satellites in the Pluto-Charon system. For the adopted masses and orbits of the known satellites, there are few stable prograde or polar orbits with semimajor axes $a \lesssim 1.1~a_H$, where $a_H$ is the semimajor axis of the outermost moon Hydra. Small moons with radii $r \lesssim$ 2 km and $a \lesssim 1.1~a_H$ are ejected on time scales ranging from several yr to more than 10 Myr. Orbits with $a \gtrsim 1.1~a_H… Expand
A Pluto–Charon Sonata: Dynamical Limits on the Masses of the Small Satellites
During 2005-2012, images from Hubble Space Telescope (HST) revealed four moons orbiting Pluto-Charon (Weaver et al 2006, Showalter et al 2011, 2012). Although their orbits and geometric shapes areExpand
A Pluto–Charon Sonata. III. Growth of Charon from a Circum-Pluto Ring of Debris
Current theory considers two options for the formation of the Pluto-Charon binary (Canup 2005, 2011; Desch 2015). In the `hit-and-run' model, a lower mass projectile barely hits the more massiveExpand
Orbital Stability of Circumstellar Planets in Binary Systems
Planets that orbit only one of the stars in stellar binary systems (i.e., circumstellar) are dynamically constrained to a limited range of orbital parameters and thus understanding conditions onExpand
On the Origin of the Pluto System
For six decades following its discovery, Pluto was the only known Sun-orbiting world in the dynamical vicinity of Neptune. An early origin concept postulated that Neptune originally had two largeExpand
Formation, Composition, and History of the Pluto System: A Post-New Horizons Synthesis
The Pluto-Charon system provides a broad variety of constraints on planetary formation, composition, chemistry, and evolution. Pluto was the first body to be discovered in what is now known as theExpand
A Pluto–Charon Concerto. II. Formation of a Circumbinary Disk of Debris after the Giant Impact
Using a suite of numerical calculations, we consider the long-term evolution of circumbinary debris from the Pluto–Charon giant impact. Initially, these solids have large eccentricity and pericentersExpand
A Pluto–Charon Concerto: An Impact on Charon as the Origin of the Small Satellites
We consider a scenario where the small satellites of Pluto and Charon grew within a disk of debris from an impact between Charon and a trans-Neptunian Object (TNO). After Charon's orbital motionExpand
