  We present a survey of coronal forbidden lines detected in Far Ultraviolet
Spectroscopic Explorer (FUSE) spectra of nearby stars. Two strong coronal
features, Fe XVIII 974 A and Fe XIX 1118 A, are observed in 10 of the 26 stars
in our sample. Various other coronal forbidden lines, observed in solar flares,
also were sought but not detected. The Fe XVIII feature, formed at log T (K) =
6.8, appears to be free of blends, whereas the Fe XIX line can be corrupted by
a C I multiplet. FUSE observations of these forbidden iron lines at spectral
resolution R ~ 15,000 provides the opportunity to study dynamics of hot coronal
plasmas. We find that the velocity centroid of the Fe XVIII feature deviates
little from the stellar rest frame, confirming that the hot coronal plasma is
confined. The observed line widths generally are consistent with thermal
broadening at the high temperatures of formation and show little indication of
additional turbulent broadening. The fastest rotating stars, 31 Com, alpha Aur
Ab, and AB Dor, show evidence for excess broadening beyond the thermal
component and the photospheric v sin i. The anomalously large widths in these
fast rotating targets may be evidence for enhanced rotational broadening
consistent with emission from coronal regions extending an additional delta R ~
0.4-1.3 R_star above the stellar photosphere or represent the turbulent
broadening caused by flows along magnetic loop structures. For the stars in
which Fe XVIII is detected, there is an excellent correlation between the
observed Rontgensatellit} (ROSAT) 0.2-2.0 keV soft X-ray flux and the coronal
forbidden line flux. As a result, Fe XVIII is a powerful new diagnostic of
coronal thermal conditions and dynamics that can be utilized to study high
temperature plasma processes in late-type stars.
