Pulsation properties of the $\beta$ Cephei star SY Equ from combined photometric and spectroscopic data

Jadwiga Daszynska-Daszkiewicz, Andrzej Pigulski

We present the analysis of simultaneous multicolour $uvy{I}_{\mathrm{C}}$ photometry and low-resolution spectroscopy for the rapidly rotating $\beta$ Cephei star SY Equ. From the photometric…
