| | The Yarkovsky Effect - Part 6 of 7 |
 | | Of course, here "starting" refers to ejection either from sizable asteroids - such as 6 Hebe, 13 Egeria, and 19 Fortuna - or from decameter-sized immediate parent bodies, which may have themselves drifted across the belt while shielding their interiors from cosmic-ray irradiation. |
 | | On the other hand, for meter-sized bodies with very low conductivities, the diurnal effect becomes very efficient, and they may drift from any starting location all the way to a resonance in a few tens of million years. |
 | | This could explain the 7-8 Ma peak of CRE ages that is observed in the CRE age distribution of H chondrites (Graf and Marti, 1995). |
