The novel oscillator is chaotic as the system's dynamics have one positive Lyapunov Exponent (LE). Also, based on the results of the equilibrium points analysis, it is shown that the oscillator has a line of equilibria, so the attractors of this system are hidden. Moreover, the study of energy dissipation of this system, power spectrum, and Poincaré sections are conducted to investigate the system's dynamics. The complex features of this system are investigated with the aid of bifurcation diagrams, LE spectra, approximate entropy, and basins of attraction. https://scientiairanica.sharif.edu/article_24213_75f8f7a9ced8da0635e455405200f2e8.pdf
