Just a Phase? Weakening Vertical Shear Instability Explains Class II Disk Morphologies: Simulations with dust coagulation, sedimentation, thermal relaxation, and backreaction
Thomas Pfeil, Alexandros Ziampras, Shangjia Zhang +2
The Vertical Shear Instability (VSI) is known to create turbulence and strong vertical mixing in protoplanetary disks if thermal relaxation is sufficiently fast. In simulations whe…
On the formation of retrograde S-type planets in binaries with a polar circumbinary disk
Cheng Chen, Philip J. Armitage, C. J. Nixon +2
Retrograde S-type planets have been observed in several binary systems, yet their formation pathway remains poorly understood. With high-resolution hydrodynamic simulations, we dem…
On the orbital evolution of binaries with polar circumbinary disks
Cheng Chen, Philip J. Armitage, C. J. Nixon
Binaries occur in many astrophysical systems, from young protostellar binaries in star forming regions to supermassive black hole binaries in galaxy centers. In many cases, a circu…
Magnetic Pressure Dominance Stabilizes AGN Disks Against Gravitational Instability
Hannalore J. Gerling-Dunsmore, Mitchell C. Begelman, Jacob B. Simon +1
Magnetic effects have long been considered a possible factor in stabilizing the outer regions of active galactic nuclei (AGN) accretion disks against gravitational instability (GI)…
Does magnetic field promote or suppress fragmentation in AGN disks? Results from local shearing box simulations with simple cooling
Tsun Hin Navin Tsung, Mitchell C. Begelman, Philip J. Armitage +2
Accretion disks in Active Galactic Nuclei (AGN) are predicted to become gravitationally unstable substantially interior to the black hole's sphere of influence, at radii where the…
Particle fragmentation inside planet-induced spiral waves
Linn E. J. Eriksson, Chao-Chin Yang, Philip J. Armitage
Growing planets interact with their surrounding protoplanetary disk, generating feedback effects that may promote or suppress nearby planet formation. We study how spiral waves lau…
