Abstract
Centaurs are objects whose orbits are found between those of the giant planets. They are supposed to originate mainly from the Trans-Neptunian objects, and they are among the sources of Near-Earth Objects. Trans-Neptunian Objects (TNOs) cross Neptune’s orbit and produce the Centaurs. We investigate their interactions with main belt asteroids to determine if chaotic scattering caused by close encounters and impacts by these bodies may have played a role in the dynamical evolution of the main belt. We find that Centaurs and TNOs that reach the inner Solar System can modify the orbits of main belt asteroids, though only if their mass is of the order of \(10^{-9} m_{\odot }\) for single encounters or, one order less in case of multiple close encounters. Centaurs and TNOs are unlikely to have significantly dispersed young asteroid families in the main belt, but they could have perturbed some old asteroid families. Current main belt asteroids that originated as Centaurs or Trans-Neptunian Objects may lie in the outer belt with short lifetime \(\leq 4~\mbox{My}\), most likely between 2.8 and 3.2 au at larger eccentricities than typical of main belt asteroids.

The diameter was computed using the equation of Tedesco et al. (1992), assuming the average albedo \(\rho_{V}=0.05\) of the Centaurs (Rabinowitz et al. 2007): \(D =\frac{1329}{\rho_{V}}10^{- \frac{H}{5}}\). In this way, we can assume a body is larger than 100 km when its absolute magnitude, \(H\lesssim 9\).
-
In practice, we examined all those below a value of 3.91 au (Helga’s aphelion), to be sure that the Centaurs and TNOs interact with this region.
-
For the Present Population, 16 % of the Centaurs and 18 % of the TNOs, for the Ancient Population 6 %. The rest of all those populations which interact with the main belt (having perihelion, \(q\lesssim 3.8\) for at least 2 kyrs, see Sect. 2) have semi-major axis \(a>3.8~\mbox{au}\).
