Lines are well fit by our four
parameter model (b is actually held
constant at b=1; so three free
parameters): z Pup’s X-ray lines
are consistent with a spatially distributed, spherically symmetric,
radially accelerating wind scenario, with reasonable parameters:
t*~1 :4 to 15 times less than predicted
Ro~1.5
q~0
But, the level of wind
absorption is significantly below what’s expected.
And, there’s no
significant wavelength dependence of the optical depth (or any
parameters).
