Physical Studies of Minor PlanetsTom Gehrels Scientific and Technical Information Office, National Aeronautics and Space Administration, 1972 - 687 Seiten " ... Some papers and discussions included in this book even though they were not presented at the meeting. In some respects, therefore, the book is independent of the colloquium. Several papers had been invited long beforehand with the request to publish them as review papers. The lack of a modern textbook on minor planets is keenly felt, and the proceedings of this meeting, with these additions, should provide a good reference book."--Page viii. |

The constants related to the reference frame will be considered in another
section. Obviously, the four element corrections to be considered for the orbit of
the Earth-Moon barycenter are easily introduced into the observation ...

Jones (1968) has studied the evolution of the mass distribution of asteroids using
a more detailed model; the contribution of fragmentation was considered but later
discarded because the size of the fragments produced during collisions was ...

The mean D(M, N) was found to be 0.045, 0.026, and 0.017, respectively, if only
the proper elements a, e', and i' are considered. AD, value between 0.015 and
0.030 thus appears reasonable. Numerically this D, value is about one-tenth of
that ...
