Gravitoelectromagnetism:
applications to the Taub-NUT spacetime |
The role of the gravitomagnetic
monopole moment of the Taub-NUT solution is studied for spinning test
particle moving along circular orbits. Comparison with the Schwarzschild case
is also considered. |

Perturbations and
gravitomagnetism in the Kerr-Taub-NUT spacetime |
The master equation describing
massless fields of different spin in the Kerr-Taub-NUT spacetime representing
a source with a mass plus gravitomagnetic monopole and dipole moments is
studied. This equation can be separated into its radial and angular parts.
The behaviour of the radial functions at infinity and near the horizon is
studied in order to examine the influence of the NUT parameter on the
phenomenon of superradiance. Moreover it is discussed the coupling between
the spin of the perturbing field and the gravitomagnetic monopole moment. |

Stability region of Neutron
Stars and Mass-Radius relation |
We present detailed analysis of
the mass radius relations in the neutron stars which outline some interesting
features about the morphology of such astrophysical object. In particular we
numerically integrate the Tolman Oppenheimer Volkoff equations in correspondence
to different choices for the core equation of state and using the standard
Harrison Wheeler scheme for modelling the external envelope; in this
procedure the central density of the star is to be regarded as a free
parameter of the theory. The results of our integration show a crucial
morphology in the {\em mass-central density diagram} which consists of the
appearence of an existence domain; this achievement allows to characterize
the astrophysical nature of an observed stellar object simply by its mass,
i.e. when its values lies outside such domain we can exclude that the object
under study is a neutron star. Furthermore we candidate (in alternative to
the {\em strange star proposal}) neutron stars cores as the astrophysical
objects responsible for the mass radius profiles observed by Beppo Sax. |

Geodesics of the Ferrari-Ibanez
metric: a computer algebra approach |
It is shown how to build a
simple computer algebra procedure to draw the geodesic paths of a particle
moving in a single gravitational plane wave spacetime, with various initial
velocities, and subsequently penetrating a GW collision zone. The software used
is Mathematica 4. |

Electrostatics on a
Reissner-Nordstrom black hole background |
The interaction of a
Reissner-Nordstr\"om black hole and a charged test particle is studied
together with the lines of force of their electric fields. The electric
properties of the black hole horizon are discussed in detail and used to
explain the expulsion of the lines of force from the outer horizon as the
hole becomes extreme. The particle backreaction is also considered studying
the effect of general static perturbations of the hole following the approach
of Zerilli. |

Astrometry and Relativity |
Since James Bradley's discovery
of light aberration (1727) to Gravity Probe-B experiment (launch November
2003) there has been a strict interplay between observational astrometry and
measurements of relativistic effects. An overview on light aberration, Mercury's
perihelion precession with solar disk ellipticity debate, lunar geodetic
precession, Lense-Thirring and Pugh-Schiff precessions in Gravity Probe-B
experiment are presented, in order to understand the final choice of the
reference star for Gravity Probe-B satellite. |
