Interlopers within Asteroid Families
A statistical method for the evaluation of the probable amount of interlopers included in the most recently identi ed asteroid families is developed. The method is based on the analysis of the local properties of the asteroidal distribution in the zones of the proper element space in which families are located. An application to the most important families listed by Zappal a et al. [1995, Icaru...
متن کاملThe shallow magnitude distribution of asteroid families
It is well known that asteroid families have steeper absolute magnitude (H) distributions for H 12–13 values than the background population. Beyond this threshold, the shapes of the absolute magnitude distributions in the family/background populations are difficult to determine, primarily because both populations are not yet observationally complete. Using a recently generated catalog containin...
متن کاملYarkovsky/YORP chronology of asteroid families
Asteroid families are the byproducts of catastrophic collisions whose fragments form clusters in proper semimajor axis, eccentricity, and inclination space. Although many families have been observed in the main asteroid belt, only two very young families, Karin and Veritas, have well-determined ages. The ages of other families are needed, however, if we hope to infer information about their eje...
متن کاملA Search for Spectro-dynamical Asteroid Families
Dynamical asteroid families are normally identified as concentrations of objects in proper orbital element space. These clusters are believed to result from the collisional disruptions of once larger parent bodies. If an asteroid family contains the remnants from such a collision, then the members of that family should be genetically related, and their range of compositions should make cosmoche...
متن کاملDynamical spreading of asteroid families by the Yarkovsky effect.
The orbital distributions of prominent asteroid families are thought to be direct by-products of catastrophic disruption events among diameter D greater, similar 100 kilometer bodies. Ejection velocities derived from studying observed families, however, are surprisingly high compared with results from impact experiments and simulations. One way to resolve this apparent contradiction is by assum...
