Quadrupole effects on the motion of extended bodies in Schwarzschild spacetime (2009)
Bini, Donato, Fortini, Pierluigi, Geralico, Andrea, Ortolan, Antonello
The motion of an extended body up to the quadrupolar structure is studied in the Schwarzschild background following Dixon's model and within certain restrictions (constant frame components for the...
Quadrupole effects on the motion of extended bodies in Kerr spacetime (2009)
Bini, Donato, Fortini, Pierluigi, Geralico, Andrea, Ortolan, Antonello
The motion of a body endowed with dipolar as well as quadrupolar structure is investigated in the Kerr background according to the Dixon's model, extending a previous analysis done in the...
Dixon's extended bodies and impulsive gravitational waves (2009)
Bini, Donato, Fortini, Pierluigi, Geralico, Andrea, Ortolan, Antonello
The "reaction" of an extended body to the passage of an exact plane gravitational wave is discussed following Dixon's model. The analysis performed shows several general features, e.g. even if...
The Stochastic Gravitational Background From Inflationary Phase Transitions (2007)
Carlo Baccigalupi, Luca Amendola, Pierluigi Fortini, Franco Occhionero
We consider true vacuum bubbles generated in a first order phase transition occurring during the slow rolling era of a two field inflation: it is known that gravitational waves are produced by the...
Gravitational Radiation from Triple Star Systems (1999)
Montanari, Enrico, Calura, Mirco, Fortini, Pierluigi
We have studied the main features of the gravitational radiation generated by an astrophysical system constituted of three compact objects attracting one another (only via gravitational interaction)...
Gravitational Wave Interaction with Normal and Superconducting Circuits (1998)
Fortini, Pierluigi, Montanari, Enrico, Ortolan, Antonello, Schaefer, Gerhard
The interaction, in the long--wavelength approximation, of normal and superconducting electromagnetic circuits with gravitational waves is investigated. We show that such interaction takes place by...
Lagrangian planetary equations in Schwarzschild space--time (1998)
Calura, Mirco, Montanari, Enrico, Fortini, Pierluigi
We have developed a method to study the effects of a perturbation to the motion of a test point--like object in a Schwarzschild spacetime. Such a method is the extension of the Lagrangian planetary...
Stochastic gravitational background from inflationary phase transitions (1997)
Baccigalupi, Carlo, Amendola, Luca, Fortini, Pierluigi, Occhionero, Franco
We consider true vacuum bubbles generated in a first order phase transition occurring during the slow rolling era of a two field inflation: it is known that gravitational waves are produced by the...
Post-Newtonian Lagrangian planetary equations (1997)
Calura, Mirco, Fortini, Pierluigi, Montanari, Enrico
We present a method to study the time variation of the orbital parameters of a Post-Keplerian binary system undergoing a generic external perturbation. The method is the relativistic extension of the...
Montanari, Enrico, Fortini, Pierluigi
The interaction of a gravitational wave with a system made of an RLC circuit forming one end of a mechanical harmonic oscillator is investigated. We show that, in some configurations, the coherent...
