Resolving the Binary Components of the Outbursting Protostar HBC 494 with ALMA
Pedro Henrique Nogueira, Alice Zurlo, Sebastián Pérez +15
Episodic accretion is a low-mass pre-main sequence phenomenon characterized by sudden outbursts of enhanced accretion. These objects are classified into two: protostars with elevat…
Misaligned disks induced by infall
M. Kuffmeier, C. P. Dullemond, S. Reissl +1
Arc- and tail-like structures associated with disks around Herbig stars can be a consequence of infall events occurring after the initial collapse phase of a forming star. An encou…
Cloudlet capture by Transitional Disk and FU Orionis stars
Cornelis Petrus Dullemond, Michael Küffmeier, Felipe Goicovic +3
After its formation, a young star spends some time traversing the molecular cloud complex in which it was born. It is therefore not unlikely that, well after the initial cloud coll…
Late encounter-events as a source of disks and spiral structures -- Forming second generation disks
M. Kuffmeier, F. G. Goicovic, C. P. Dullemond
Both observations of arc-like structures and luminosity bursts of stars > 1 Myr in age indicate that at least some stars undergo late infall events. We investigate scenarios of rep…
Hydrodynamical moving-mesh simulations of the tidal disruption of stars by supermassive black holes
Felipe G. Goicovic, Volker Springel, Sebastian T. Ohlmann +1
When a star approaches a black hole closely, it may be pulled apart by gravitational forces in a tidal disruption event (TDE). The flares produced by TDEs are unique tracers of oth…
Accretion of clumpy cold gas onto massive black holes binaries: the challenging formation of extended circumbinary structures
Cristián Maureira-Fredes, Felipe G. Goicovic, Pau Amaro-Seoane +1
Massive black hole binaries (MBHBs) represent an unavoidable outcome of hierarchical galaxy formation, but their dynamical evolution at sub-parsec scales is poorly understood, due…
Accretion of clumpy cold gas onto massive black hole binaries: a possible fast route to binary coalescence
Felipe G. Goicovic, Cristian Maureira-Fredes, Alberto Sesana +2
In currently favoured hierarchical cosmologies, the formation of massive black hole binaries (MBHBs) following galaxy mergers is unavoidable. Still, due the complex physics governi…
Infalling clouds on to supermassive black hole binaries - II. Binary evolution and the final parsec problem
Felipe G. Goicovic, Alberto Sesana, Jorge Cuadra +1
The formation of massive black hole binaries (MBHBs) is an unavoidable outcome of galaxy evolution via successive mergers. However, the mechanism that drives their orbital evolutio…
Formation of discs around super-massive black hole binaries
Felipe G. Goicovic, Jorge Cuadra, Alberto Sesana
We model numerically the evolution of turbulent molecular clouds in near-radial infall onto , equal-mass super-massive black hole binaries, using a modif…
