15 صفحه اولTime evolution of the linear perturbations of a rotating Newtonian polytrope
We present the results of numerical time evolutions of the linearised perturbations of rapidly and rigidly rotating Newtonian polytropes while making the Cowling approximation. The evolution code runs stably for hundreds of stellar rotations, allowing us to compare our results with previously published eigenmode calculations, for instance the f-mode calculations of Ipser & Lindblom, and the r-m...
متن کاملNon-extensive statistics and the stellar polytrope index
Polytropic distribution functions provide the simplest models for self-gravitating stellar systems [1]. These models are characterized by an equation of the state of the form p = Kρ , where K and γ are constants. The polytropic index n is defined by the following expression: γ = 1 + 1 n which in the limit n → ∞ or, equivalently, γ = 1 results in an equation of state identical to the one of an i...
متن کاملRapidly rotating fermi gases
We show that the density profile of a Fermi gas in rapidly rotating potential will develop prominent features reflecting the underlying Landau-level-like energy spectrum. Depending on the aspect ratio of the trap, these features can be a sequence of ellipsoidal volumes or a sequence of quantized steps.
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.
