What happens when 2 young stars with surrounding discs collide in star forming regions? When they encounter, one or both stars start wildly accreting disc material. This translates into spectacular (FU Orionis-type) outbursts. A sort of stellar firework! [Read More]

How do planets form around binary stars? The answer lies in their migration due to interactions with the protoplanetary disc. 🌌🪐 #Astrophysics #PlanetFormation [Read More]

“Stellar flybys can shape planet-forming discs!” A review of the literature in the past 30 years shows how tidal perturbations affect planet formation. [Read More]

Abstract: 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 year rise in the mass accretion rate to 10−4 Msun/yr that remains... [Read More]
