Disk Detective: Discovery of New Circumstellar Disk Candidates through Citizen Science
Marc J. Kuchner, Steven M. Silverberg, Alissa S. Bans +23
The Disk Detective citizen science project aims to find new stars with 22 micron excess emission from circumstellar dust using data from NASA's WISE mission. Initial cuts on the Al…
Secular models and Kozai resonance for planets in coorbital non-coplanar motion
Cristian A. Giuppone, Alejandro M. Leiva
In this work, we construct and test an analytical and a semianalytical secular models for two planets locked in a coorbital non-coplanar motion, comparing some results with the cas…
Chaotic Diffusion in the Gliese-876 Planetary System
J. G. Martí, P. M. Cincotta, C. Beaugé
Chaotic diffusion is supposed to be responsible for orbital instabilities in planetary systems after the dissipation of the protoplanetary disk, and a natural consequence of irregu…
Giga-Year Evolution of Jupiter Trojans and the Asymmetry Problem
Romina P. Di Sisto, Ximena S. Ramos, Cristián Beaugé
We present a series of numerical integrations of observed and fictitious Jupiter Trojan asteroids, under the gravitational effects of the four outer planets, for time-spans compara…
