Debris Disc Substructures Induced by Secular Planetary Perturbations
Roman R. Rafikov, Deniz Akansoy, Antranik A. Sefilian
Observations of debris discs have the potential to provide us with valuable information about massive planets perturbing them gravitationally. In this work, we explore the evolutio…
-mapping of planet-induced density wave damping in protoplanetary discs
Amelia J. Cordwell, Roman R. Rafikov
Planets embedded in protoplanetary discs are capable of creating a wide variety of substructures through gravitational interactions. This process is mediated through the excitation…
Indirect forces in disc-planet interaction
Roman R. Rafikov, Nicolas P. Cimerman, Callum W. Fairbairn +1
Gravitational coupling between a protoplanetary disc and an embedded planet is often studied in a frame attached to a central star. This frame is non-inertial because of the stella…
Conservation laws in non-inertial frames and non-conservation of energy of relative motion in two-body problem
Roman R. Rafikov
The dynamics of systems of multiple gravitationally interacting bodies is often studied in a frame attached to one of the objects (e.g. a central star in a planetary system). As th…
Wave-Mediated Boundary Layers of Accretion Discs: Role of Internal Structure of the Accretor
Samuel G. D. Turner, Roman R. Rafikov, Alexander A. Philippov
Disc accretion onto astrophysical objects with a material surface proceeds through the boundary layer (BL) -- a radially narrow region in the inner disc where the incoming gas must…
How two-dimensional are planet--disc interactions? I. Locally isothermal discs
Amelia J. Cordwell, Alexandros Ziampras, Joshua J. Brown +1
Planet--disc interactions, despite being fundamentally three-dimensional, are often studied in the two-dimensional `thin-disk' approximation. The overall morphology of planet--disc…
