Such orbits were taken immersed in a mathematical model for the gravitational potential that simulates a barred galaxy in a system with two degrees of freedom.
We apply the SALI method in the study of stellar orbits immersed in a gravitational potential of barred galaxies, once the movement of a test particle in a rotating three-dimensional model of a barred galaxy is given by the Hamiltonian:
NGC 7090 is a beautiful, bright, large and very elongated galaxy in a north-west to south-east direction, and is actually a barred galaxy seen edge-on.
High power, however, will reveal this distorted barred galaxy to have an elongated nucleus.
Higher power reveals the bar extending a great distance along the halo of this barred galaxy.
