First Results of the 17th DSN Campaign: Photometry of XX Pyx

We present the first results from multi-site observations of the δ Scuti star XX Pyx (CD–24°7599). The observations were carried out as the 17th run of the Delta Scuti Network. We collected 583 hr of B , V time-series photometry, resulting in a detection level (4 σ ) in the amplitude spectrum of 0.5...

Zusammenfassung:We present the first results from multi-site observations of the δ Scuti star XX Pyx (CD–24°7599). The observations were carried out as the 17th run of the Delta Scuti Network. We collected 583 hr of B , V time-series photometry, resulting in a detection level (4 σ ) in the amplitude spectrum of 0.5 mmag. We detect 6 new pulsation frequencies, bringing the total number of frequencies known in this star up 19.
