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…
Gravitational torque in circumbinary discs: global radial oscillations
Nicolas P. Cimerman, Roman R. Rafikov
Circumbinary discs (CBDs) arise in many astrophysical settings, including young stellar binaries and supermassive black hole binaries. Their structure is mediated by gravitational…
Torque wiggles -- a robust feature of the global disc-planet interaction
Nicolas P. Cimerman, Roman R. Rafikov, Ryan Miranda
Gravitational coupling between planets and protoplanetary discs is responsible for many important phenomena such as planet migration and gap formation. The key quantitative charact…
Vortex weighing and dating of planets in protoplanetary discs
Roman R. Rafikov, Nicolas P. Cimerman
High-resolution sub-mm observations of some protoplanetary discs reveal non-asixymmetric features, which can often be interpreted as dust concentrations in vortices that form at th…
Emergence of vortices at the edges of planet-driven gaps in protoplanetary discs
Nicolas P. Cimerman, Roman R. Rafikov
Young planets embedded in protoplanetary discs (PPDs) excite spiral density waves, which propagate, shock and deposit angular momentum in the disc. This results in gap opening arou…
Planet-driven density waves in protoplanetary discs: numerical verification of nonlinear evolution theory
Nicolas P. Cimerman, Roman R. Rafikov
Gravitational coupling between protoplanetary discs and planets embedded in them leads to the emergence of spiral density waves, which evolve into shocks as they propagate through…
Formation of a planetary Laplace resonance through migration in an eccentric disk - The case of GJ876
Nicolas P. Cimerman, Wilhelm Kley, Rolf Kuiper
Orbital mean motion resonances in planetary systems originate from dissipative processes in disk-planet interactions that lead to orbital migration. In multi-planet systems that ho…
Hydrodynamics of embedded planets' first atmospheres - III. The role of radiation transport for super-Earth planets
Nicolas P. Cimerman, Rolf Kuiper, Chris W. Ormel
The population of close-in super-Earths, with gas mass fractions of up to 10% represents a challenge for planet formation theory: how did they avoid runaway gas accretion and colla…
