Abstract:
WX Eri is an eclipsing binary system for which one component was
reported to show Delta 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 Delta Scuti type pulsations of WX Eri. However, no
evidence for the presence of such oscillations was found in our data.
Description:
Photometric V and B CCD time-series observations of WX Eri, obtained
at the South African Astronomical Observatory (SAAO), Beersel Hills
Observatory (BH), Las Campanas Observatory (LCO), European Southern
Observatory (ESO), Sternwarte Hoher List (HOLI/HOLIr) and at Esteve
Duran Observatory (EDO) during 2001 and early 2002. The measurements
from the different observatories was merged and shifted to standard
values.
