Web30 de abr. de 2024 · Gabriele Bozzola, Pedro Luis Espino, Collin Davis Lewin, Vasileios Paschalidis We construct equilibrium models of uniformly and differentially rotating hybrid hadron-quark stars using equations of state (EOSs) with a first-order phase transition that gives rise to a third family of compact objects. Webthe modes can drive a uniformly rotating star into differ-ential rotation via non-linear effects (Rezzolla et al 2000; Levin & Ushomirsky 2001; Lindblom, Tohline & Vallisneri 2001). A differentially rotating massive neutron star may also be generated following a binary neutron star merger. The maximum mass of a differentially rotating
Web1 de ago. de 2024 · If the star is rotating, as the plasma bubble moves radially outwards it is also pushed sideways, just like when you throw a ball while standing on a merry-go-round. (It is called Coriolis effect ). The sideways push will be stronger for plasma bubbles on the equatorial plane, because their velocity is orthogonal to the axis of rotation. WebAbstract. In this paper we study the compressible fluid model of uniformly rotating starts. It was proved in [Li] that for a given mass, there exists an equilibrium solution to the …
Web9 de jan. de 2009 · We calculate Keplerian (mass shedding) configurations of rigidly rotating neutron stars and quark stars with crusts. We check the validity of empirical … WebMagnetic braking and viscosity combine to drive the star to uniform rotation, even if the seed magnetic field and the viscosity are small. This process inevitably leads to delayed collapse, which will be accompanied by a delayed gravitational wave …
