Tremaine to Receive 1997 Brouwer Award
It was announced that Dr. Scott D. Tremaine, of the University
of Toronto, was the winner of the 1997 Dirk Brouwer Award of the
Division on Dynamical Astronomy, in recognition of his many
outstanding contributions to a wide range of dynamical problems
in both solar-system and galactic dynamics. Among his major
contributions to solar-system dynamics are predictions of
density waves in planetary rings and the existence of "shepherd"
satellites, models of the Kuiper belt and of the Oort cloud of
comets, and pioneering efforts to carry out accurate numerical
integrations of the long-term evolution of the solar system.
His major contributions to galactic dynamics include studies of
the stability of stellar systems, of the consequences of
dynamical friction, of the nature of dark galaxy halos and their
effects on warps in galactic disks, of the interactions of bars
with other galaxy components, and of the measurement of bar
pattern speeds. With James Binney, he is the author of Galactic
Dynamics, a work which has become a classic and the standard
reference in this field.
