A Search for Rapid Oscillations in Fg-Sagittae
Abstract
It has recently been noted that the spectrum of the peculiar variable star FG Sge is beginning to resemble that of HD 101065 (Przybylski's star). Since Przybylski's star is known to show light variations of 0.01 mag with a period of 12.14 min, a search for similar rapid oscillations in FG Sge was carried out. This paper presents 25 hr of high-speed photometry of FG Sge which show that it has no variations in the frequency-range 0.5 to 10.0 mHz larger than 1.2 mmag peak-to-peak.
