, . . Where May Be Hidden Asteroid Parent Bodies? Busarev V. V. (Sternberg State Astronomical Institute, Moscow, Russian Federation). From analysis of observational data and results of contemporary cosmogonic models a conclusion is made that fragments of asteroid parent bodies may be covered with a layer of atypical shattered matter and inaccessible in some cases for remote investigations. A hypothesis is propounded on a postaccretionary period of asteroid dust evolution.
