Scientific paper

The authors investigate the orbital evolutions of numbered asteroids which are supposed to be located near the secular resonance ν6 according to Williams' list (1979). The asteroidal orbits are integrated numerically over 1 Myr in the four-body model Sun-Jupiter-Saturn-asteroid. Only the two asteroids (759) Vinifera and (1222) Tina are found to be located deeply in the ν6 secular resonance. The asteroid (2368) Beltovata is at present also situated in this secular resonance. Presumably, Beltovata will be removed from the resonance due to a close approach to Jupiter. Beltovata is a possible candidate to become an Apollo asteroid. The dynamical topology of the ν6 secular resonance seems to be similar to the mean motion resonance. The authors conjecture that also for the ν6 resonance, a separatrix-like region separates librators from circulators. Only those parts of the ν6 secular resonance region, where libration with large amplitudes occurs, have to be considered as possible sources of meteorites.
