Gravitational wave generation in power-law inflationary models
Paulo M. Sá, Alfredo B. Henriques
We investigate the generation of gravitational waves in power-law inflationary models. The energy spectrum of the gravitational waves is calculated using the method of continuous B…

The role of differential rotation in the evolution of the r-mode instability
Paulo M. Sá, Brigitte Tomé
We discuss the role of differential rotation in the evolution of the l=2 r-mode instability of a newly born, hot, rapidly-rotating neutron star. It is shown that the amplitude of t…

The r-mode instability: Analytical solution with gravitational radiation reaction
Oscar J. C. Dias, Paulo M. Sa
Analytical r-mode solutions are investigated within the linearized theory in the case of a slowly rotating, Newtonian, barotropic, non-magnetized, perfect-fluid star in which the g…
