PZ Aquilae: period changes in a population II Cepheid.

WALLENTINSEN D.

Abstract (from CDS):

The photometric behavior of the galactic variable PZ Aquilae is examined during the fifty years 1934 - 1983. Using photographic observations from the Maria Mitchell Observatory, two intervals of constant period were found. The current period is 8.7546 days.
