The Greatly Expanded IUE Spectrum of the Planetary Nebula NGC 2371-2 and Its Central Star

Abstract

Early IUE low-dispersion SWP and LWR spectra have been reexamined by means of refined current data reduction routines. These spectra contain much more information than was reported in 1981. A high-dispersion SWP spectrum was obtained in 1994 from which more than 80 emission and absorption features were identified, and log N_e = 3.0 +/- 0.2 cm^-3 was determined from the C III] F(λ1907/λ1909) ratio. Electron densities were also derived from the Si III] F(λ1883/λ1892) and dereddened [Ne IV] F[λ1602/(λ2422 + λ2424)] line ratios. The terminal wind velocity of the C IV P Cyg feature was measured from the low- and high-resolution spectra. Approximately 50 of the strongest Fe VI and Fe V photospheric absorptions are identified.
