| Description | The short periodic light changes were detected in the light curve of the eclipsing binary TW Dra by Kusakin et al. (2001) and later confirmed by Kim et al. (2003). We have re-analysed old photometric UBV data obtained by Papoušek et al. at Skalnaté Pleso, Slovakia (1967-1980) and Brno, Czech Republic (1976-9) observatories and analysed new own CCD measurements (Brno, 2003-2005). In both set of data the oscillations were found. Both detected periods are in good agreement with the previously published results. |
