A Pluto-Charon Sonata V. Long-term Stability of the HST State Vector
Scott J. Kenyon, Benjamin C. Bromley
We analyze a new set of 275 n-body calculations designed to place limits on the masses of the small circumbinary satellites in the Pluto-Charon system. Together with calculations r…
Polarization of circumstellar debris disk light echoes
Austin J. King, Benjamin C. Bromley, Preston W. Harris +1
Light echoes of debris disks around active stars can reveal disk structure and composition even when disks are not spatially resolved. Unfortunately, distinguishing reflected light…
Magnetic interactions in orbital dynamics
Benjamin C. Bromley, Scott J. Kenyon
The magnetic field of a host star can impact the orbit of a stellar partner, planet, or asteroid if the orbiting body is itself magnetic or electrically conducting. Here, we focus…
A Pluto--Charon Sonata IV. Improved Constraints on the Dynamical Behavior and Masses of the Small Satellites
Scott J. Kenyon, Benjamin C. Bromley
We discuss a new set of 500 numerical n-body calculations designed to constrain the masses and bulk densities of Styx, Nix, Kerberos, and Hydra. Comparisons of different tec…
From Pebbles and Planetesimals to Planets and Dust: the Protoplanetary Disk--Debris Disk Connection
Joan R. Najita, Scott J. Kenyon, Benjamin C. Bromley
The similar orbital distances and detection rates of debris disks and the prominent rings observed in protoplanetary disks suggest a potential connection between these structures.…
Collisions in a gas-rich white dwarf planetary debris disc
Andrew Swan, Scott J. Kenyon, Jay Farihi +5
WD 0145+234 is a white dwarf that is accreting metals from a circumstellar disc of planetary material. It has exhibited a substantial and sustained increase in 3-5 micron flux sinc…
A Pluto--Charon Concerto II. Formation of a Circumbinary Disk of Debris After the Giant Impact
Scott J. Kenyon, Benjamin C. Bromley
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 eccentric…
On the Estimation of Circumbinary Orbital Properties
Benjamin C. Bromley, Scott J. Kenyon
We describe a fast, approximate method to characterize the orbits of satellites around a central binary in numerical simulations. A goal is to distinguish the free eccentricity --…
Craters on Charon: Impactors From a Collisional Cascade Among Trans-Neptunian Objects
Scott J. Kenyon, Benjamin C. Bromley
We consider whether equilibrium size distributions from collisional cascades match the frequency of impactors derived from New Horizons crater counts on Charon (Singer et al 2019).…
A Pluto-Charon Concerto: An Impact on Charon as the Origin of the Small Satellites
Benjamin C. Bromley, Scott J. Kenyon
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…
A Pluto-Charon Sonata III. Growth of Charon from a Circum-Pluto Ring of Debris
Scott J. Kenyon, Benjamin C. Bromley
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 th…
Ohmic heating of asteroids around magnetic stars
Benjamin C. Bromley, Scott J. Kenyon
We consider the impact of electromagnetic induction and Ohmic heating on a conducting planetary object that orbits a magnetic star. Power dissipated as heat saps orbital energy. If…
A Pluto--Charon Sonata: Dynamical Limits on the Masses of the Small Satellites
Scott J. Kenyon, Benjamin C. Bromley
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 geom…
A Pluto-Charon Sonata: The Dynamical Architecture of the Circumbinary Satellite System
Scott J. Kenyon, Benjamin C. Bromley
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,…
Follow-up Imaging of Disk Candidates from the Disk Detective Citizen Science Project: New Discoveries and False-Positives in WISE Circumstellar Disk Surveys
Steven M. Silverberg, Marc J. Kuchner, John P. Wisniewski +17
The Disk Detective citizen science project aims to find new stars with excess 22-m emission from circumstellar dust in the AllWISE data release from the Wide-field Infrared Surv…
Dust Production and Depletion in Evolved Planetary Systems
J. Farihi, R. van Lieshout, P. W. Cauley +15
The infrared dust emission from the white dwarf GD 56 is found to rise and fall by 20% peak-to-peak over 11.2 yr, and is consistent with ongoing dust production and depletion. It i…
Terrestrial planet formation: Dynamical shake-up and the low mass of Mars
Benjamin C. Bromley, Scott J. Kenyon
We consider a dynamical shake-up model to explain the low mass of Mars and the lack of planets in the asteroid belt. In our scenario, a secular resonance with Jupiter sweeps throug…
Searching for Planet Nine with Coadded WISE and NEOWISE-Reactivation Images
Aaron M. Meisner, Benjamin C. Bromley, Peter E. Nugent +4
A distant, as yet unseen ninth planet has been invoked to explain various observations of the outer solar system. While such a 'Planet Nine', if it exists, is most likely to be dis…
Rocky Planet Formation: Quick and Neat
Scott J. Kenyon, Joan R. Najita, Benjamin C. Bromley
We reconsider the commonly held assumption that warm debris disks are tracers of terrestrial planet formation. The high occurrence rate inferred for Earth-mass planets around matur…
Disk Detective: Discovery of New Circumstellar Disk Candidates through Citizen Science
Marc J. Kuchner, Steven M. Silverberg, Alissa S. Bans +23
The Disk Detective citizen science project aims to find new stars with 22 micron excess emission from circumstellar dust using data from NASA's WISE mission. Initial cuts on the Al…
Making Planet Nine: A Scattered Giant in the Outer Solar System
Benjamin C. Bromley, Scott J. Kenyon
Correlations in the orbits of several minor planets in the outer solar system suggest the presence of a remote, massive Planet Nine. With at least ten times the mass of the Earth a…
Making Planet Nine: Pebble Accretion at 250--750 AU in a Gravitationally Unstable Ring
Scott J. Kenyon, Benjamin C. Bromley
We investigate the formation of icy super-Earth mass planets within a gravitationally unstable ring of solids orbiting at 250-750 AU around a 1 solar mass star. Coagulation calcula…
