Abstract

Simultaneous uvby photometric observations of the high amplitude  Sct star BS Aqr have been collected and new times of light maxima were obtained. Additionally, some observations are also presented. The light curves have been analysed and the physical parameters of this star are determined. The results indicate that BS Aqr is an evolved monoperiodic  Sct star, with solar abundances, pulsating radially in the fundamental mode.

Key words: ffi Scu stars: individual: BS Aqr stars: oscillations techniques: photometric
