Rabe, Eugene Abstract It is shown, on the basis of the energy integral of the lunar or stellar type of the three-body problem, that, in consequence of accretion and orbital friction relative to nebular matter, the development of dynamically unstable pairs of asteroid condensations into stable binary configurations would have been possible during the early formative period, before the dissipation of the solar nebula. Continued accretion and friction would have caused the components of such stable pairs to spiral in toward each other, until contact and the formation of one combined, rapidly rotating body was achieved. If the condensations had a density of 2.0 gm/cm3, the minimum period of rotation of asteroids formed in this manner would amount to about 4 7 hours, which is in close agreement with the observed periods Publication: The Astrophysical Journal Pub Date: January 1960 DOI: 10.1086/146824 Bibcode: 1960ApJ...131..231R full text sources ADS |
