The Oort cloud as a remnant of the protosolar nebula
... by Whitworth & Summers (1985, Table 1), there is no solution of Eqs. (10) and (11) in the range of zc /zs from 1.955 to 3755. Hence, the value zc /zs = 1.955 appears to be natural as the second border of acceptability. To avoid numerical difficulties in numerical integration at the true border, we a ...
