Figure showing the relationship between the circular orbital radius and the tidal radius for a 1 M star as the impactor. According to the simulation results, in most cases only the brighter of the two eruptions is observable, so the observed QPE period effectively corresponds to the star’s orbital period (Torb = TQPE).
