López-Suspes F., G. A. González: Thick Disks with newtonian multipolar moments. Rev. Acad. Colomb. Cienc. 37 (144) p.301-305 2013

We present a new family of stable thick discs from known displace, cut, fill and reflect method (González & Letelier, 2004; Vogt & Letelier, 2005) is presented. Solutions of the Laplace equation in cylindrical coordinates are considered, these one represent the gravitational field of objects with only external multipole moments. Are defined and calculated the physical quantities intheplane oft hedisk,suchas, the epicyclic frequency,κ,the vertical frequency,ν, andthecircular velocity,vc of particles. Also, it was calculated the surface density,σ, density of thick disk,ρ, and stability of thick disks through of specific angular momentum or Rayleigh criterion (Rayleigh, 1917), and (Landau, 1987). Finally, the physical properties are shown for only some parameters considering only until quadrupolar term in the expasion gravitational potential multipolar Key words: Thick disk, Rayleigh, epicyclic frequency, and multipole.
