Chaotic diffusion caused by close encounters with several massive asteroids The (4) Vesta case
(Edp Sciences S A, 2012-07-01)
Context. Close encounters with massive asteroids are known to be a mechanism of dynamical mobility that can significantly alter proper elements of minor bodies, and they are the main source of dynamical mobility for ...

The journey of Typhon-Echidna as a binary system through the planetary region
(2018-06-01)
Among the current population of the 81 known trans-Neptunian binaries (TNBs), only two are in orbits that cross the orbit of Neptune. These are (42355) Typhon-Echidna and (65489) Ceto-Phorcys. In this work, we focused our ...

Planet Detectability in the Alpha Centauri System
(Institute of Physics Publishing, 2018)
We use more than a decade of radial-velocity measurements for α Cen A, B, and Proxima Centauri from the High Accuracy Radial Velocity Planet Searcher, CTIO High Resolution Spectrograph, and the Ultraviolet and Visual Echelle ...
Does the presence of planets affect the frequency and properties of extrasolar kuiper belts? Results from the Hershel Drebis and Dunes Surveys
(The American Astronomical Society, 2015)
The study of the planet–debris disk connection can shed light on the formation and evolution of planetary
systemsand may help “predict” the presence of planets around stars with certain disk characteristics. In
preliminary ...
The empty primordial asteroid belt
(Amer Assoc Advancement Science, 2017-09-01)
The asteroid belt contains less than a thousandth of Earth's mass and is radially segregated, with S-types dominating the inner belt and C-types the outer belt. It is generally assumed that the belt formed with far more ...
Patterns, Causes, and Consequences of Anthropocene Defaunation
(2016-11-01)
Anthropocene defaunation, the global extinction of faunal species and populations and the decline in abundance of individuals within populations, has been predominantly documented in terrestrial ecosystems, but indicators ...
