Inner main belt asteroids in Slivan states?

Popis výsledku v původním jazyce

Context. The spin state of ten asteroids in the Koronis family has previously been determined. Surprisingly, all four asteroids with prograde rotation were shown to have spin axes nearly parallel in the inertial space. All asteroids with retrograde rotation had large obliquities and rotation periods that were either short or long. The Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect has been demonstrated to be able to explain all these peculiar facts. In particular, the effect causes the spin axes ofthe prograde rotators to be captured in a secular spin-orbit resonance known as Cassini state 2, a configuration dubbed "Slivan state". Aims. It has been proposed based on an analysis of a sample of asteroids in the Flora family that Slivan states mightalso exist in this region of the main belt. This is surprising because convergence of the proper frequency s and the planetary frequency s(6) was assumed to prevent Slivan states in this zone. We therefore investigated the possibility of
