The nonlinear oscillator x″+(2m+3)x2m+1 x+x+x 4m+3=0, with m a non-negative integer, is known to have a center in the origin, in a neighborhood of which are isochronous orbits, i.e., orbits with fixed period, not dependent on the amplitude. Here, we show that this oscillator can be explicitly integrated, and that its phase space can be completely characterized. © 2011 American Physical Society.
