TY - JOUR ID - 42087 AU - Kotrlová, Andrea - Stuchlík, Zdeněk - Török, Gabriel PY - 2008 TI - Quasiperiodic oscillations in a strong gravitational field around neutron stars testing braneworld models JF - Classical and Quantum Gravity VL - 2008 IS - 25 SN - 02649381 KW - QPO, neutron star, brany universe, tidal charge N2 - The strong gravitational field of neutron stars in the brany universe could be described by spherically symmetric solutions with a metric in the exterior to the brany stars being of the Reissner Nordström type containing a brany tidal charge representingthe tidal effect of the bulk spacetime onto the star structure. We investigate the role of the tidal charge in orbital models of high-frequency quasiperiodic oscillations (QPOs) observed in neutron star binary systems. We focus on the relativistic precession model. We give the radial profiles of frequencies of the Keplerian (vertical) and radial epicyclic oscillations. ER -
