Substructure evolution from protoplanetary to debris disks driven by mutually gravitating planetesimals and implications on Kepler resonances and free-floating planets
Yinuo Han, Konstantin Batygin, Fei Dai
Motivated by recent observations suggesting rings found in debris disks are wider than those in protoplanetary disks, we consider a picture in which planetesimals formed in radiall…
Distant TNO Inclinations as a Constraint on Primordial Cluster Perturbations in the Presence of Planet Nine
Avni Bansal, Ian Brunton, Konstantin Batygin +2
The Sun was almost certainly born in a stellar cluster, implying some degree of external forcing from neighboring stars during the Solar System's infancy. Published estimates of th…
A young progenitor for the most common planetary systems in the Galaxy
John H. Livingston, Erik A. Petigura, Trevor J. David +39
The Galaxy's most common known planetary systems have several Earth-to-Neptune-size planets in compact orbits. At small orbital separations, larger planets are less common than the…
Secular Excitation of Polar Neptune Orbits in Pure Disk-Planet Systems
Luke B. Handley, Konstantin Batygin
The stellar spin-orbit angles of Neptune-sized planets present a primordial yet puzzling view of the planetary formation epoch. The striking dichotomy of aligned and perpendicular…
A constraint on the density of Jupiter's moon Thebe from primordial dynamics
Ian R. Brunton, Konstantin Batygin
Of the 97 known satellites in the Jovian system, the individual masses and densities of each moon have only been determined for six of them: the four Galileans, Amalthea, and Himal…
On the origin and dynamical evolution of Jupiter's moon Amalthea
Ian R. Brunton, Konstantin Batygin
Interior to the orbits of Jupiter's iconic Galilean moons are four small satellites with individual mean radii, km. Multiple lines of evidence suggest that these bod…
