The words of this preface were written when the book was ready to
go to the press; and are limited to only a few points which are
best made in this place. As is intimated by the sub-title, the
whole volume was written with appli cations in mind to double-star
astronomy. The latter is, however, not the only branch of our
science which could benefit from its contents. The same is true of
certain aspects of the dynamics of stellar systems or galaxies (the
stellar popula tions of which are also characterized by the fact
that the mean-free-path of their constituent stars are long in
comparison with the dimensions of the respective systems); the
central condensations of which are high enough to approximate the
gravitational action of a "mass-point." This fact did not, to be
sure, escape the attention of previous investigators (in the case
of globular clusters, in particular, the Roche model was introduced
in their studies under the guise of polytropic models characterized
by the index n = 5); though no particular attention will be paid to
these in this book. But possible applications of the Roche model
are not limited to problems arising in stellar astrophysics. With
Coulomb forces replacing gravitation, the equilibrium model finds a
close analogy in the field of electrostatics-as was pointed out
already at the beginning of this century by (then young) J. H.
Jeans (cf."
