  • Closure of the stellar hydrodynamic equations for Gaussian and ellipsoidal velocity distributions 

    Cubarsí Morera, Rafael (2007-06-07)
    External research report
    Open Access
    The closure conditions, which make a finite set of moment equations equivalent to the collisionless Boltzmann equation, are investigated for Gaussian and ellipsoidal velocity distributions working from the com- plete ...
  • Eccentricity samples: implications on the potential and the velocity distribution 

    Cubarsí Morera, Rafael; Stojanovic, Milan; Ninkovic, Slobodan (2017)
    Article
    Open Access
    Planar and vertical epicycle frequencies and local angular velocity are related to the derivatives up to the second order of the local potential and can be used to test the shape of the potential from stellar disc samples. ...
  • Warp evidence in precessing galactic bar models 

    Sanchez Martin, P; Romero Gómez, Mercè; Masdemont Soler, Josep (EDP Sciences, 2016-04-01)
    Article
    Open Access
    Most galaxies have a warped shape when they are seen edge-on. The reason for this curious form is not completely known so far, so in this work we apply dynamical system tools to contribute to its explanation. Starting from ...
