On the rise times in FU Orionis events.

Abstract (from CDS):

We examine whether stellar flyby simulations can initiate FU Orionis outbursts using 3D hydrodynamics simulations coupled to live Monte Carlo radiative transfer. We find that a flyby where the secondary penetrates the circumprimary disc triggers a 1-2 yr rise in the mass accretion rate to 10–4 M☉ yr–1 that remains high (>=10–5 M☉ yr–1) for more than a hundred years, similar to the outburst observed in FU Ori. Importantly, we find that the less massive star becomes the dominant accretor, as observed.
