摘要: ABSTRACT Rotation period clustering in prograde/retrograde rotators might be the preliminary indication of the Slivan state in the Koronis family as a result of the Yarkovsky-O'Keefe-Radzievskii-Paddack effect. We follow the general scenario of dispersion in the semimajor axis of the asteroid family members to separate prograde and retrograde rotators in the Koronis family. From the available rotation periods obtained from PTF/iPTF, we were unable to find the rotation period clustering of objects with H 12 mag in the Koronis family. This could be the result of the intermittent collisional process of small asteroids (D 20 km) which leads to astray Yarkovsky drifting. Measurement of the pole orientations of our sample will verify our preliminary result and validate our method. 其他題名: APJ 其他題名: Astrophys.
