| Abstract: |
Recent radio pulsar observations have shown that
some pulsars
have interesting long term period variations which can be approximated by a sum
of periodic functions. Such periodicities could be explained as
free precession of a pulsar or as evidence of a planetary system around it
(like PSR 1257+12).
We present pulsar timing simulations of three dynamic models of
precessing neutron star: homogeneous rigid body,
Zhukovski-Volterra gyrostat (rigid body carrying rotator inside) and
rigid mantle with
a triaxial ellipsoidal cavity filled with inviscid fluid. |
