Ever since the first observations of sunspots in the early seventeenth
century, stellar rotation has been a major topic in astronomy and
astrophysics. Jean-Louis Tassoul synthesizes a large number of
theoretical investigations on rotating stars. Drawing upon his own
research, Professor Tassoul also carefully critiques various competing
ideas.
In the first three chapters, the author provides a short historical
sketch of stellar rotation, the main observational data on the Sun and
other stars on which the subsequent theory is based, and the basic
Newtonian hydrodynamics used to study rotating stars. Following a
discussion of some general mechanical properties of stars in a state of
permanent rotation, he reviews the main techniques for determining the
structure of a rotating star and its stability with respect to
infinitesimal disturbances. Since the actual distribution of angular
momentum within stars is still unknown, Professor Tassoul considers
various models of angular momentum as well as of meridional circulation.
He devotes the rest of his study to the problems concerning various
groups of stars and stages in stellar evolution.
