TL;DR: In this article, numerical simulations of a disc-planet system using various grid-based and smoothed particle hydrodynamics (SPH) codes are performed for a simple setup where Jupiter and Neptune mass planets on a circular orbit open a gap in a protoplanetary disc during a few hundred orbital periods.

Journal ArticleDOI
Intermediate mass black holes in AGN discs – I. Production and growth
Barry McKernan,Barry McKernan,Barry McKernan,K. E. S. Ford,K. E. S. Ford,K. E. S. Ford,Wladimir Lyra,Wladimir Lyra,Hagai B. Perets +8 more
TL;DR: In this article, the authors proposed a mechanism for efficiently growing intermediate mass black holes (IMBH) in discs around supermassive black holes, where the IMBH seeds can grow extremely rapidly by collisions with disc NCOs at low relative velocities, allowing for super-Eddington growth rates.

Journal ArticleDOI
Planet formation bursts at the borders of the dead zone in 2D numerical simulations of circumstellar disks
TL;DR: In this article, the formation and evolution of the vortices were studied in detail, focusing on the implications for the dynamics of embedded solid particles and planet formation, and the authors found evidence that the backreaction of the drag force from the particles onto the gas modifies the evolution of Rossby wave instability, with vortice being launched only at later times if this term is excluded from the momentum equation.
