Spectral approach to the relativistic inverse stellar structure problem II
The inverse stellar structure problem determines the equation of state of the matter in stars from a knowledge of their macroscopic observables (e.g. their masses and radii). This problem was solved in a previous paper by constructing a spectral representation of the equation of state whose stellar models match a prescribed set of macroscopic observables. This paper improves and extends that wo...
متن کاملThe Stellar Dynamics Toolbox
NEMO is a toolbox for users and programmers with which a wide range of experimental situations can be constructed, dynamically evolved, and analyzed. Primarily geared towards stellar dynamics, NEMO is by no means restricted to it. Great importance has been given to making the package extendible and to exibly import and export data. NEMO has been implemented within, and integrated into, the UNIX...
متن کاملThe Stellar Dynamics of !
The stellar dynamics of ! Centauri are inferred from the radial velocities of 469 stars measured with CORAVEL (Mayor et al. 1997). Rather than t the data to a family of models, we generate estimates of all dynamical functions nonparametrically, by direct operation on the data. The cluster is assumed to be oblate and edge-on but mass is not assumed to follow light. The mean motions are consisten...
متن کاملQuantitative Stellar Spectral Classification . Iii . Spectral Resolution
The method developed by Stock & Stock (1999) to derive absolute magnitudes and intrinsic colors is applied to simulated low-resolution spectra. The simulation is made by convolving real spectra with a Gaussian function, σ (the full width at half maximum), related to the final spectral resolution. The accuracy with which the stellar parameters are determined indicates that the method may be appl...
متن کاملStellar dynamics of blue compact galaxies II . Further
Context. Luminous blue compact galaxies, common at z ∼ 1 but now relatively rare, show disturbed kinematics in emission lines. Aims. As part of a programme to understand their formation and evolution, we have investigated the stellar dynamics of a number of nearby objects in this class. Methods. We obtained long-slit spectra with VLT/FORS2 in the spectral region covering the near-infrared calci...
