WX Eri is an eclipsing binary system for which one component was reported to show δ Scuti type pulsations with periods close to integer fractions of the orbital period. This makes it an interesting candidate for investigating the interaction between binarity and pulsation and a potential new member of the recently defined group of mass-accreting pulsating components (gainers) in semi-detached Algol binaries called “oscillating EA” stars. We present new photometric time-series observations of this star. The Wilson-Devinney code was applied to find the best fitting model for the eclipsing binary's light curve. The aim of the observations was to investigate the short-period δ Scuti type pulsations of WX Eri. However, no evidence for the presence of such oscillations was found in our data.
Key words: stars: binaries: eclipsing / stars: individual: WX Eri / stars: oscillations / δ Sct
Based on observations obtained at the South African Astronomical Observatory, ESO, Las Campanas, Beersel Hills, Hoher List and Esteve Duran Observatories.
