On the asphericity of the figures of Pluto and Charon
A Pluto–Charon Sonata: The Dynamical Architecture of the Circumbinary Satellite System
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…

New Horizons Photometry of Pluto's Moon Charon
The New Horizons spacecraft extended the range in solar phase angle coverage for Pluto’s moon Charon from 1.°8—the maximum observable from Earth—to 170°. This extraordinary expansion in range has…

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. In the hit-and-run model, a lower mass projectile barely hits the more massive Pluto, kicks up some debris, and…
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. Although their orbits and geometric shapes are well-known, the 2σ uncertainties in the masses of…

Charon's Radius and Density from the Combined Data Sets of the 2005 July 11 Occultation
The 2005 July 11 C313.2 stellar occultation by Charon was observed by three separate research groups, including our own, at observatories throughout South America. Here, the published timings from…
Albedo Maps of Pluto and Improved Physical Parameters of the Pluto-Charon System
Abstract We present an analysis of photometric observations of the Pluto-Charon rotational and mutual event light curves obtained between 1982 and 1990. The dataset covers 18 satellite transits…
Pluto's Radius and Atmosphere: Results from the Entire 9 June 1988 Occultation Data Set
We have analyzed all photometric observations of the 9 June 1988 occultation of the star P8 by Pluto in order to derive the radius of Pluto and certain parameters of its atmosphere. Our analysis is…
Charon's size and an upper limit on its atmosphere from a stellar occultation
TLDR
Observations from a multi-station stellar occultation by Charon are reported, which are used to derive the radius of Pluto and Charon, RC = 603.6 ± 1.4 km (1σ), and the density of ρ = 1.71 ± 0.08 g cm-3.3 (3σ) nanobar, assuming respectively a pure nitrogen or pure methane atmosphere.
Separate Lightcurves of Pluto and Charon
We present new Hubble Space Telescope observations of the Pluto–Charon system taken with WFPC1 (PC6) between 1992 May 21 and 1993 August 18. Our observations consist of 52 images with the F555W…
The Pluto system: Initial results from its exploration by New Horizons
TLDR
The New Horizons encounter revealed that Pluto displays a surprisingly wide variety of geological landforms, including those resulting from glaciological and surface-atmosphere interactions as well as impact, tectonic, possible cryovolcanic, and mass-wasting processes.

A Pluto-like radius and a high albedo for the dwarf planet Eris from an occultation
TLDR
The observation of a multi-chord stellar occultation by Eris on 6 November 2010 is reported, consistent with a spherical shape for Eris, and it is anticipated that this atmosphere may periodically sublimate as Eris approaches its perihelion, at 37.8 astronomical units from the Sun.
