Top-shaped Asteroids as Lens-shaped Bodies
Anthony R. Dobrovolskis, Jack J. Lissauer, Jose L. Alvarellos
Several asteroids are known to be shaped like toy tops. This paper models Top-Shaped Asteroids (TSAs) as Homogeneous Symmetric Lenses (HSLs), and derives their rotational, self-gra…
Synchronous Satellites of Venus
Anthony R. Dobrovolskis, Jose Luis Alvarellos
Synchronous satellites of Venus have long been thought unstable, but we use Poincare's surface of section technique to show that synchronous quasi-satellites orbiting just outside…
The Role of Ejecta in the Small Crater Populations on the Mid-Sized Saturnian Satellites
Edward B. Bierhaus, Luke Dones, José Luis Alvarellos +1
We find evidence that crater ejecta play an important role in the small crater populations on the Saturnian satellites, and more broadly, on cratered surfaces throughout the Solar…
Exchange of ejecta between Telesto and Calypso: Tadpoles, horseshoes, and passing orbits
Anthony R. Dobrovolskis, Jose' Luis Alvarellos, Kevin J. Zahnle +1
We have numerically integrated the orbits of ejecta from Telesto and Calypso, the two small Trojan companions of Saturn's major satellite Tethys. Ejecta were launched with speeds c…
