_{5}region of Mars could have formed in a collision. We estimate the size distribution index from available information on family members; model the orbital dispersion of collisional fragments; and carry out a formal calculation of the collisional lifetime as a function of size. We find that, as initially conjectured by Rivkin...

**274**, 314 (2016)) we have developed a new method to estimate the ages of asteroid families, based on an analysis of some expected consequence of the YORP effect acting on family members. The method is based on the identification of what we called the YORP eye, namely a region of depletion of the domain occupied by family members in the absolute magnitude - orbital semi-major...

_{139}, recently discovered by the Pan‐STARRS1 survey telescope, shares a common physical origin. By applying the hierarchical clustering and backward integration methods, we find strong evidence that 11 of these asteroids form a sub‐group which likely...

_{1}, G

_{2}magnitude phase function for asteroids starting from the current two-parameter H, G phase function. We describe stochastic optimization of the basis functions of the magnitude phase function based on a carefully chosen set of asteroid photometric observations covering the principal types of phase dependencies. We then illustrate the magnitude...
