Nebular properties from far-infrared spectrosopy
We describe a semiempirical methodology-based on measurements of far-infrared (FIR) lines-that yields information on electron densities in regions where various ionic species exist, effective temperatures (T(sub eff)) for stars ionizing H II regions, and gas-phase heavy element abundances. Although this capability has long been available via optica...
Velocity-resolved far-infrared spectra of forbidden Fe II - Evidence for mixing and clumping in SN 1987A
The forbidden F II profiles at 18 and 26 micron from SN 1987A have been measured with a resolution of about 400 km/s. The central portion of each profile is well-fitted by a Gaussian with a FWHM of 2900 and 2500 km/s, respectively. The centroid velocity is redshifted relative to the LSR by 450 + or - 200 km/s at 18 microns and by 680 + or - 200 km/...

An 8 million channel spectrum analyzer (MCSA) was designed the meet to meet the needs of a SETI program. The MCSA puts out a very large data base at very high rates. The development of a device which follows the MCSA, is presented.
