Ultrashort-Period Stellar Oscillations. I. Results from White Dwarfs, Old Novae, Central Stars of Planetary Nebulae, 3c 273, and Scorpius XR-1
Abstract
Power spectra which are most reliable for Fourier components in the 2- to approximately 300-sec range have been measured for a number of stellar objects. Null results are presented for six white dwarfs and a magnetic star. Nova T Corona Borealis was found to have periodic fluctuations in the 100-second range. Preliminary results for 3C 273 and Scorpius XR-t are briefly discussed.
