In globally coupled ensembles of identical oscillators so-called chimera states can be observed. The chimera state is a symmetry-broken regime, where a subset of oscillators forms a cluster, a synchronized population, while the rest of the system remains a collection of non-synchronized, scattered units. We describe here a blinking chimera regime in an ensemble of seven globally coupled rotators (Kuramoto oscillators with inertia). It is characterized by a death-birth process, where a long-term stable cluster of four oscillators suddenly dissolves and is very quickly reborn with a new, reshuffled configuration.We identify three different kinds of rare blinking events and give a quantitative characterization by applying stability analysis to the long-lived chaotic state and to the short-lived regular regimes which arise when the cluster dissolves.Coupled oscillators can synchronize if the coupling is attractive, or desynchronize if the coupling is repulsive. This basic effect is captured by the famous Kuramoto-Sakaguchi model of phase oscillators. However, if inertia is included, i.e. the units are rotators, more complex regimes in between synchrony and asynchrony can be observed. One such regime is a chimera pattern, where some rotators form a fully synchronous, perfect cluster, while the others are non-synchronized and all mutually different. In this paper we report one such a chimera characterized by an interesting additional long-time dynamics. We call it a blinking chimera because every once in a while an event occurs where the cluster opens up and quickly closes into a new reorganized composition. This event takes place on a time scale much shorter than that of the very long chaotic transient that is the chimera pattern -the system blinks. We describe in detail how the exchange between the cluster and desynchronized units takes place.
