Electron Temperatures of Planetary Nebulae Determined from the He I Discontinuities
Y. Zhang, H. -B. Yuan, C. -T. Hua +3
We have used the He I discontinuities at 3421A to determine the electron temperatures, designated Te(He I), for a sample of five Galactic planetary nebulae (PNe). We compared Te(He…
