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…
Do Tides Destabilize Trojan Exoplanets?
Anthony R. Dobrovolskis, Jack J. Lissauer
One outstanding problem in extrasolar planet studies is why no co-orbital exoplanets have been found, despite numerous searches among the many known planetary systems, many of them…
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 Tethered Moon
Kevin J. Zahnle, Roxana Lupu, Anthony Dobrovolskis +1
We address the thermal history of the Earth after the Moon-forming impact, taking tidal heating and thermal blanketing by the atmosphere into account. The atmosphere sets an upper…
Viscous liquid flow on Martian dune slopes
Anthony R. Dobrovolskis
The observed temporary dark streaks on some dune slopes on Mars may be due to thin sheets of water (or some other liquid) trickling downhill. This note corrects conceptual errors i…
Radial Velocities of Stars with Multiple Co-orbital Planets
Anthony R. Dobrovolskis
To date, well over a thousand planets have been discovered orbiting other stars, hundreds of them in multi-planet systems. Most of these exoplanets have been detected by either the…
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…
Size-selective concentration of chondrules and other small particles in protoplanetary nebula turbulence
Jeffrey N. Cuzzi, Robert C. Hogan, Julie M. Paque +1
Size-selective concentration of particles in a weakly turbulent protoplanetary nebula may be responsible for the initial collection of chondrules and other constituents into primit…
