Abstract: The complete FORTRAN codified programs of the segregation algorithm described in Alcobé (2001) are described. The classification algorithm is applied to study the trivariate velocity distribution of stars from the star catalogs, which can be locally approximated by a superposition of two or more normal components. An auxiliar sampling parameter P (such as the velocity module referred to a specific point, the absolute value of one peculiar velocity component alone, the distance to the galactic plane, etc.) is introduced in order to define the sample boundaries. The sampling paramenter must induce a hyerarchical incorporation of stars to the population components, in the sense that the greater the P value, the greater the number of stars in each component. For a fixed P, a sample S(P) is drawn from the global catalog. Depending on the sampling parameter the population entropy H(P) of a two-component mixture is computed from the mixing proportions. The purpose is to find the optimal P value in order to maximize H(P). Then the algorithm is used recursively in order to segregate a global sample in more than two populations. Moreover, for each subsample S(P), the goodness of the superposition approximation is evaluated by reconstructing the sample central moments up to fourth-order from the population parameters. A chi-square test, taking into account the sampling distribution moments, is evaluated to measure the fitting error. For subsamples S(P) a total accordance between the minimum chi-square and the maximum population entropy H(P) is produced.Mon, 18 Apr 2011 10:03:50 GMThttp://hdl.handle.net/2117/124042011-04-18T10:03:50ZCubarsí Morera, Rafael; Alcobé López, SantiagonoThe complete FORTRAN codified programs of the segregation algorithm described in Alcobé (2001) are described.

Title: Closure of the stellar hydrodynamic equations for arbitrary distributions
Authors: Cubarsí Morera, Rafael
Abstract: The closure problem of the stellar hydrodynamic equations is studied in a general case by describing the family of phase space density functions for which the collisionless Boltzmann equation is strictly equivalent to a finite subset of moment equations.
The method is based on the use of maximum entropy distributions, which are afterwards generalised to phase space density functions depending on any isolating integral of motion in terms of a polynomial function of degree $n$ in the velocities. Then, there is an independent set of velocity moments, up to an order $n$, so that the higher-order moments can be expressed in terms of the independent moments; the collisionless Boltzmann equation is given by a set of differential equations expressed from symmetric tensors of rank up to $n+1$;
the independent moment equations are those of an order of up to $n+1$; and the hydrodynamic equations of an order higher than $n+1$ are redundant.Fri, 04 Mar 2011 13:52:59 GMThttp://hdl.handle.net/2117/116782011-03-04T13:52:59ZCubarsí Morera, RafaelnoThe closure problem of the stellar hydrodynamic equations is studied in a general case by describing the family of phase space density functions for which the collisionless Boltzmann equation is strictly equivalent to a finite subset of moment equations.
