New biorthogonal potential--density basis functions
Alireza Rahmati, Mir Abbas Jalali
We use the weighted integral form of spherical Bessel functions, and introduce a new analytical set of complete and biorthogonal potential--density basis functions. The potential a…

Unstable Disk Galaxies. II. the Origin of Growing and Stationary Modes
Mir Abbas Jalali
I decompose the unstable growing modes of stellar disks to their Fourier components and present the physical mechanism of instabilities in the context of resonances. When the equil…

Unstable modes of non-axisymmetric gaseous discs
Naser M. Asghari, Mir Abbas Jalali
We present a perturbation theory for studying the instabilities of non-axisymmetric gaseous discs. We perturb the dynamical equations of self-gravitating fluids in the vicinity of…
