Do the other O supergiants, z
Ori and d Ori, fit into
the wind-shock paradigm?
The
strong lines in these other O supergiants can also be fit by the simple
spherically symmetric wind model
d Ori Fe XVII 15.01 Å
z Ori O VIII 18.97 Å
Though they
are clearly less asymmetric and a little narrower
t*=0
t*=0.4
