Default Accretion disc rigidity

I know that binary systems with a neutron star and a regular star at
close orbital distances can result in matter being stripped off the star

Neutron star X-ray binaries are pretty common. Cygnus X-2 is one
famous example. The X-rays come from an accretion disk.

... high frequency oscillations will be radiated away or
straight up absorbed via turbulence, considering the nature of an
accretion disk.


I think the part about turbulence is right, though I'm not sure
"absorbed" is quite the right word. I don't see how waves in plasma
can be "radiated away," though, whether the restoring force is
pressure or gravity.
