Asteroid age distributions determined by space weathering and collisional evolution models
Mark Willman, Robert Jedicke
We provide evidence of consistency between the dynamical evolution of main belt asteroids and their color evolution due to space weathering. The dynamical age of an asteroid's surf…
Formation of asteroid pairs by rotational fission
P. Pravec, D. Vokrouhlicky, D. Polishook +23
Asteroid pairs sharing similar heliocentric orbits were found recently. Backward integrations of their orbits indicated that they separated gently with low relative velocities, but…
YORP effect with anisotropic radiation
Slawomir Breiter, David Vokrouhlicky
The influence of optical scattering and thermal radiation models an the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect is studied. Lambertian formulation is compared with Hapk…
Using the youngest asteroid clusters to constrain the Space Weathering and Gardening rate on S-complex asteroids
Mark Willman, Robert Jedicke, Nicholas Moskovitz +3
We have extended our earlier work on space weathering of the youngest S-complex asteroid families to include results from asteroid clusters with ages <10^6 years and to newly ident…
