The ASCA Solid
State Imaging
|
|
|
|
Spectrometer
observation of Cyg X-
|
|
|
3 did indeed
confirm the presence of
|
|
|
|
Fe K emission in
the spectrum, but
|
|
|
indicated that it
was far from the
|
|
|
|
most prominent
feature.

Liedahl &
Paerels showed that in
|
|
|
|
addition to
H-like and He-like line
|
|
|
emission from
lower-Z elements, we
|
|
|
also see narrow
radiative
|
|
|
recombination
continua (RRCs).

These indicate
that the line emitting
|
|
|
|
gas is
photoionized - suspected, but
|
|
|
never previously
demonstrated for
|
|
|
|
accretion-powered
sources.
