High-Frequency Stellar Oscillations. V. Power Spectra for the Central Stars of Planetary Nebulae
Abstract
Photoelectric time-series data have been used to calculate power spectra for the central stars of sixteen planetary nebulae. No periodic activity is evident in the range from 4 to 700 seconds. The continua of the power spectra have also been examined; no clear differences from those for white dwarfs are evident.
