Sorry Henry, when you fit the curves mathematically
it is certain that there is just one layer a few
hundred km thick that moves by more than a million
km over the cycle. Your handwaving is wrong by
about 5 orders of magnitude because you didn't do
the maths again.

I have the right equation for it while, you can't
even derive that (see my other post on that topic),
and your handwaving estimates are out by several
orders of magnitude in many cases.

Tough, we know their radius varies by a significant
factor (12% for L Car) from three different methods
all of which give the same answer and all of which
are valid for ballistic theory as well as conventional.

The basic principle is acoustic ringing mostly
in the radial direction but with some contribution
from transverse modes. Numerous harmonics can be
measured within the overall curves and their phase
relative to the fundamental can be predicted quite
well by conventional physics. Ballistic theory won't
make a significant difference to the acoustics of
the gas so there is no mileage in arguing that aspect.
