THE LENSE-THIRRING EFFECT
Theoretical understanding, experimental verification and observational
evidence --- around the Earth, Neutron Stars and Black Holes
June 29 -- July 4, 1998
ICRA, University of Rome "La Sapienza"; ICRA Network , Pescara
The Lense-Thirring effect first pointed out by Lense (1917) and
Thirring (1918) in connection with the precession of the orbital plane
of an orbiting body around a rotating mass within Einstein's theory of
gravity, then in its infancy, remains even today the source of a
variety of fundamental theoretical and experimental/observational
questions. This spin-orbital angular momentum coupling of the
gravitational interaction is one of a number of related issues
involving the behavior of test bodies around rotating masses which will
be explored in this first ICRA workshop confronting theory with both
experiment and observation in the spirit of the previous two meetings
honoring Bill Fairbank.
This general topic which has come to be known as gravitomagnetism has
seen considerable progress in its understanding over the years, but
there is still much to learn. Falling under the wider umbrella of
gravitoelectromagnetism, the analogy between the linear theory of
electromagnetism and linearized general relativity which extends to the
nonlinear regime through the introduction of test observer formalism,
it has provided the stimulus to develop a clearer picture of the
theoretical framework of extending space-plus-time language and
concepts to strong field gravity. Among the novel ideas this has
flushed out has been some of the interesting properties of noninertial
forces like the centrifugal force within general relativity and related
behavior of spinning test bodies. Although the orbits of nonspinning
particles in the stationary geometries of neutron stars and black holes
are rather well understood, we are still far from a complete
understanding of the behavior of spinning particles in gravitational
fields and of the implications of the different theoretical approaches
to this problem. It is possible that analogies between the treatment in ...
