Dynamical Friction in a Gaseous Medium
Using time-dependent linear perturbation theory, we evaluate the dynamical friction force on a massive perturber Mp traveling at velocity V through a uniform gaseous medium of density ρ0 and sound speed cs. This drag force acts in the direction −V̂ , and arises from the gravitational attraction between the perturber and its wake in the ambient medium. For supersonic motion (M ≡ V/cs > 1), the en...
متن کاملNonlinear Dynamical Friction in a Gaseous Medium
Using high-resolution, two-dimensional hydrodynamic simulations, we investigate nonlinear gravitational responses of gas to, and the resulting drag force on, a very massive perturber Mp moving at velocity Vp through a uniform gaseous medium of adiabatic sound speed a∞. We model the perturber as a Plummer potential with softening radius rs, and run various models with differing A = GMp/(a 2 ∞rs)...
متن کاملDynamical friction for accelerated motion in a gaseous medium
ABSTRACT Dynamical friction arises from the interaction of a perturber and the gravitational wake it excites in the ambient medium. This interaction is usually derived assuming that the perturber has a constant velocity. In realistic situations, motion is accelerated as for instance by dynamical friction itself. Here, we study the effect of acceleration on the dynamical friction force. We chara...
متن کاملForces and torques on rotating spirochete flagella.
Spirochetes are a unique group of motile bacteria that are distinguished by their helical or flat-wave shapes and the location of their flagella, which reside within the tiny space between the bacterial cell wall and the outer membrane (the periplasm). In Borrelia burgdorferi, rotation of the flagella produces cellular undulations that drive swimming. How these shape changes arise due to the fo...
متن کاملMicroscopic Calculation of Spin Torques and Forces
Spin torques, that is, effects of conduction electrons on magnetization dynamics, are calculated microscopically in the first order in spatial gradient and time derivative of magnetization. Special attention is paid to the so-called β-term and the Gilbert damping, α, in the presence of electrons’ spin-relaxation processes, which are modeled by quenched magnetic impurities. Two types of forces t...
