Closure of the stellar hydrodynamic equations for Gaussian and ellipsoidal velocity distributions
(2007-06-07)
Report de recerca
Accés obertThe 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
(2017)
Article
Accés obertPlanar 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. ...
