The Dynamical Origins of the Dark Comets and a Proposed Evolutionary Track
Aster G. Taylor, Jordan K. Steckloff, Darryl Z. Seligman +5
So-called 'dark comets' are small, morphologically inactive near-Earth objects (NEOs) that exhibit nongravitational accelerations inconsistent with radiative effects. These objects…
Reflected Light Curves, Spherical and Bond Albedos of Jupiter- and Saturn-like Exoplanets
Ulyana Dyudina, Xi Zhang, Liming Li +5
Reflected light curves observed for exoplanets indicate bright clouds at some of them. We estimate how the light curve and total stellar heating of a planet depend on forward and b…
Secular Resonance Between Iapetus and the Giant Planets
Matija Äuk, Luke Dones, David Nesvorný +1
Using numerical integrations, we find that the orbital eccentricity of Saturn's moon Iapetus undergoes prominent multi-Myr oscillations. We identify the responsible resonant argume…
Dynamical Evidence for a Late Formation of Saturn's Moons
Matija Äuk, Luke Dones, David Nesvorný
We explore the past evolution of Saturn's moons using direct numerical integrations. We find that the past Tethys-Dione 3:2 orbital resonance predicted in standard models likely di…
A Spiral Structure in the Inner Oort Cloud
David Nesvorny, Luke Dones, David Vokrouhlicky +5
As the Galactic tide acts to decouple bodies from the scattered disk it creates a spiral structure in physical space that is roughly 15,000 au in length. The spiral is long-lived a…
Considerations on the magnitude distributions of the Kuiper belt and of the Jupiter Trojans
Morbidelli Alessandro, Harold F. Levison, William Bottke +2
By examining the absolute magnitude (H) distributions (hereafter HD) of the cold and hot populations in the Kuiper belt and of the Trojans of Jupiter, we find evidence that the Tro…
