Ring Spacing from a Fourth-Order Radial Feedback Green Function in a Keplerian Accretion Disk
Yiwei Bao, Can Cui
ALMA observations of protoplanetary disks reveal ubiquitous concentric ring structures whose origin remains debated. We present an exactly solvable local model for ring spacing in…
Rossby wave instability in weakly ionized protoplanetary disks. II. radial B-fields
Can Cui, Zijin Wang
Building on our first paper in this series, we investigate the impact of radial magnetic fields and non-ideal magnetohydrodynamic (MHD) effects - specifically, Ohmic resistivity, H…
Dust Growth in ALMA Rings: II. Dusty Rossby Wave Instability
Can Cui, Konstantin Gerbig, Ya-Ping Li +5
Annular substructures serve as ideal venues for planetesimal formation. In this series, we investigate the linear stage of dust growth within rings. The first paper examines the gl…
Rossby wave instability in weakly ionized protoplanetary disks. I. azimuthal or vertical B-fields
Can Cui, Ashutosh Tripathi, Cong Yu +2
Rossby wave instability (RWI) is considered the underlying mechanism to crescent-shaped azimuthal asymmetries, discovered in (sub-)millimeter dust continuum of many protoplanetary…
