We show that pre-existing circumstellar discs around both stars result in fast rising ($\\sim$yrs) outbursts lasting 2-5 times longer than for a star-disc flyby. The perturber always goes into outburst ($\\dot{M}>10^{-5}~{\\rm M_{\\odot}~ yr^{-1}}$). Whereas we find that the primary goes into a decades long outburst only when the flyby is retrograde to the circumprimary disc rotation. High accretion rates during the outburst are triggered by angular momentum cancellation in misaligne","authors_text":"Christophe Pinte, Daniel J. Price, Elisabeth M. A.
