Acoustic oscillations of rapidly rotating polytropic stars
Context. With the launch of space missions devoted to asteroseismology (like COROT), the scientific community will soon have accurate measurements of pulsation frequencies in many rapidly rotating stars. Aims. The present work focuses on the effects of rotation on pulsations of rapidly rotating stars when both the Coriolis and centrifugal accelerations require a non-perturbative treatment. Meth...
متن کاملModeling Rapidly Rotating Stars
We review the quest of modeling rapidly rotating stars during the past 40 years and detail the challenges to be taken up by models facing new data from interferometry, seismology, spectroscopy... We then present the progress of the ESTER project aimed at giving a physically self-consistent model for the structure and evolution of rapidly rotating stars.
متن کاملDeformation of Rapidly Rotating Compact Stars *
1 Abstract. We have developed a numerical code to study the deformation (ε = (I zz − I xx)/I zz , where I ii are the moments of inertia) of neutron stars in rapidly rotation in a fully general relativistic calculation. We have found that the deformation is larger, depending on the angular velocity, than is generally assumed for gravitational wave estimations. Calculations were performed by empl...
متن کاملProperties of non-rotating and rapidly rotating protoneutron stars
Properties of non-rotating and rapidly rotating protoneutron stars and neutron stars are investigated. Protoneutron stars are hot, lepton rich neutron stars which are formed in TypeII supernovae. The hot dense matter is described by a realistic equation of state which is obtained by extending a recent approach of Myers and Świa̧tecki to the nuclear mass formula. We investigate the properties of ...
متن کاملLight Curves for Rapidly-rotating Neutron Stars
We present raytracing computations for light emitted from the surface of a rapidly-rotating neutron star in order to construct light curves for X-ray pulsars and bursters. These calculations are for realistic models of rapidly-rotating neutron stars which take into account both the correct exterior metric and the oblate shape of the star. We find that the most important effect arising from rota...
