On the close optical companion of V1494 Aql: problems with light curve modelling

Abstract

New observations of the eclipsing nova V1494 Aql were analysed in order to estimate the effect of the optical companion located 1.4 arcsec southwest. R and I-band images (stellar FWHM~1.2-1.4 arcsec) taken close to the primary minimum were used to determine relative magnitude differences between the nova and the companion, which were found to be Delta R~0.20 mag and Delta I~0.52 mag (in the sense nova minus companion). After correcting R-band time-series observations for the secondary light, the eclipse depth has been found to be almost twice as deep. Before modelling any late eclipsing light curve that is available in the literature, the data must be corrected for the light of the companion.
