About this document
Nonlinear Drag on Circular Orbit Perturbers by Luciano Del Valle is a document available to read on EtoBox.
This document describes a study using hydrodynamic simulations to investigate nonlinear gravitational drag forces on massive perturbers moving in circular orbits through a gaseous medium. Key findings include: (1) The density wake of supersonic perturbers consists of an envelope, bow shock, and low-density region, with the shock distance reduced compared to linear trajectories. (2) The orbit-averaged gravity modifies the preshock density depending weakly on parameters M and B. (3) For massive perturbers, a
