Large dust fractions can prevent the propagation of soundwaves
arXiv:2104.13787 · doi:10.1093/mnras/stab931
Abstract
Dust plays a central role in several astrophysical processes. Hence the need of dust/gas numerical solutions, and analytical problems to benchmark them. In the seminal dustywave problem, we discover a regime where sound waves can not propagate through the mixture above a large critical dust fraction. We characterise this regime analytically, making it of use for testing accuracy of numerical solvers at large dust fractions.
