Constraints for the realistic equation of state of dense matter from the dynamical evolution of compact star space-times

Obiettivo

Earth-based experiments, the possible way to explore experimentally the regime of presently unknown equation of state of matter for densities higher than the nuclear saturation density, is to rely on the astrophysical observations.

We should therefore study neutron stars in order to discover the mysteries of extremely dense matter physics, and to provide information about dynamical processes taking place in the Universe. Moreover, for present day neutron stars are the most promising sources of gravitational waves - the accurate theoretical waveforms are essential for detection.

I propose to study the time evolution of neutron stars - physical processes present in binary systems at the last stage of in spiral phase, elastic properties of the crust in spinning-down pulsars, stability of non-linear modes for rapidly rotating stars, dynamical re-configuration of the star structure during phase transitions, collapse of supra-massive neutron star, as well as, in each case, direct computation of resulting gravitational wave emission.

All mentioned above physical processes hopefully observed in future by neutrino, electromagnetic and gravitational wave detectors will carry a certain imprint of underlying dense matter physics. The problems will be solved analytically and numerically by means of the state-of-the-art pseudo-spectral multi-domain scientific library LORENE, developed by Paris-Meudon world-leading team of scientists.

From a global point of view, the project agrees well with the collective multi-disciplinary effort carried out in Europe to consolidate the scientific community, and strengthen the collaboration with other international groups.
