The mechanism of limit cycle instabilities in accretion disks is well known from the modeling of outbursts of dwarf novae. This paper investigates how such a limit cycle works in more extended disks without the confinement from the tidal forces of a secondary star. The properties of the limit cycle for different values of the viscosity parameter alpha are studied, and variations are found in the accretion rate which produce light curves of different shape, ranging from sinusoidal small amplitude changes to outbursts of dwarf novae type. The possibility that the observed lightcurve for SN 1987A might include contributions due to accretion from a disk around the remnant are discussed. Such contributions could show periodic changes produced by a limit cycle instability.
