Dynamical Model for the Zodiacal Cloud and Sporadic Meteors
David Nesvorny, Diego Janches, David Vokrouhlicky +3
The solar system is dusty, and would become dustier over time as asteroids collide and comets disintegrate, except that small debris particles in interplanetary space do not last l…
Dynamics of Dust Particles Released from Oort Cloud Comets and Their Contribution to Radar Meteors
David Nesvorny, David Vokrouhlicky, Petr Pokorny +1
The Oort Cloud Comets (OCCs), exemplified by the Great Comet of 1997 (Hale-Bopp), are occasional visitors from the heatless periphery of the solar system. Previous works hypothesiz…
Young Solar System's Fifth Giant Planet?
David Nesvorny
Recent studies of solar system formation suggest that the solar system's giant planets formed and migrated in the protoplanetary disk to reach resonant orbits with all planets insi…
Observed Binary Fraction Sets Limits on the Extent of Collisional Grinding in the Kuiper Belt
David Nesvorny, David Vokrouhlicky, William F. Bottke +2
The size distribution in the cold classical Kuiper belt can be approximated by two idealized power laws: one with steep slope for radii R>R* and one with shallow slope for R<R*, wh…
