Simultaneous uvby photometry of the new δ Sct-type variable HD 205.

Abstract (from CDS):

The star HD 205 has been discovered to be a new δ Sct-type pulsator through simultaneous uvby photometric observations carried out during the autumn of 2001. A few Hβ-Crawford measurements were also collected. The calibration of the Stroemgren photometric indices places this star in the middle part of the δ Sct instability strip. The behaviour of the light curves is shown to be very complex with a lot of frequencies necessary to fit the data. The data in the bands v, b and y were analyzed separately to confirm detected pulsations and then combined using a weighting scheme to maximize the signal-to-noise ratio. Nine frequencies were detected with the present data, but several more are probably present. The majority of the detected frequencies are due to nonradial low order p-modes as is commonl in δ Sct variables.
