Active Galactic Nucleus Tori: Potential Birthplace to Millions of Planets
Bhupendra Mishra, Wladimir Lyra, Barry McKernan +3
The outer regions of AGN disks have temperatures similar to those of circumstellar disks, permitting dust condensation. Therefore, planet formation and growth could be active in th…
AGN Disks as Supernova Mufflers I: 3D Local Hydrodynamic Models
Harrison E. Cook, Wladimir Lyra, Mordecai-Mark Mac Low +2
Supernova (SN) shocks that originate from stars on orbits embedded in dense active galactic nuclei (AGN) accretion disks evolve differently from those that occur in the interstella…
Where are the missing Kuiper Belt binaries?
Wladimir Lyra
In this letter, we call attention to a gap in binaries in the Kuiper belt in the mass range between 10-10 kg, with a corresponding dearth in binaries between…
Planetesimal and planet formation in transient dust traps
Zs. Sándor, O. M. Guilera, Zs. Regály +1
The ring-like structures in protoplanetary discs that are observed in the cold dust emission by ALMA, might be explained by dust aggregates trapped aerodynamically in pressure maxi…
Streaming Instability and Turbulence: Conditions for Planetesimal Formation
Jeonghoon Lim, Jacob B. Simon, Rixin Li +6
The streaming instability (SI) is a leading candidate for planetesimal formation, which can concentrate solids through two-way aerodynamic interactions with the gas. The resulting…
Turbulent stresses as a function of shear rate in a local disk model
A. J. Liljeström, M. J. Korpi, P. J. Käpylä +2
We present local numerical models of accretion disk turbulence driven by the magnetorotational instability with varying shear rate. The resulting turbulent stresses are compared wi…
