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)…

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…

Comets and Planetesimal Formation

Jacob B. Simon, Jürgen Blum, Til Birnstiel +1

In this chapter, we review the processes involved in the formation of planetesimals and comets. We will start with a description of the physics of dust grain growth and how this is…

The Streaming Instability Cannot Form Planetesimals from mm-size Grains in Pressure Bumps

Daniel Carrera, Jacob B. Simon

We present evidence that it is unlikely that the streaming instability (SI) can form planetesimals from mm grains inside axisymmetric pressure bumps. We conducted the largest simul…

Hydro-, Magnetohydro-, and Dust-Gas Dynamics of Protoplanetary Disks

G. Lesur, B. Ercolano, M. Flock +16

The building of planetary systems is controlled by the gas and dust dynamics of protoplanetary disks. While the gas is simultaneously accreted onto the central star and dissipated…

Using Bayesian Deep Learning to infer Planet Mass from Gaps in Protoplanetary Disks

Sayantan Auddy, Ramit Dey, Min-Kai Lin +2

Planet induced sub-structures, like annular gaps, observed in dust emission from protoplanetary disks provide a unique probe to characterize unseen young planets. While deep learni…
