cds-question@unistra.frmultiple-starsvisible-astronomyV583 Lyr is an extremely low-mass-ratio Algol-type binary with an orbital period of 11.2580days. We determined an effective temperature of Teff1=9000{+/-}350K from newly observed spectra, which might be an underestimate due to binary mass transfer. The binary mass ratio q=0.1{+/-}0.004 and the orbital inclination i=85.5deg are determined based on the assumption that the secondary fills its Roche lobe and rotates synchronously. The radial velocity curve is obtained from time series spectra, allowing for improved estimation of stellar masses and radii: M1=3.56{+/-}0.5M{sun}, R1=2.4{+/-}0.2R{sun}; and M2=0.36{+/-}0.02M{sun}, R2=6.9{+/-}0.4R{sun}. The variations in the double-peaked H{alpha} emission indicate the formation of a stable disk during mass transfer. V583Lyr appears to be a post-mass-reversal system, according to the mass transfer estimated using O-C period analysis. Its orbital period is slowly increasing, from which the rate of mass accretion by the primary star is estimated to be M_1_=3.384x10^-8^M{sun}/yr. The pulsation analysis was conducted on the residuals of the light curve. The primary component was found to be a g-mode pulsating star with 26 frequencies extracted lower than 9/day. The frequency groups and rotational splitting properties of the g mode were studied in detail. This study provides compelling evidence for an accretion disk surrounding the g-mode pulsating primary.2024AJ....167..215Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/167/215CatalogResearchIsServedByTAP VizieR generic servicerelated-toVI/39 : Model Atmospheres (Kurucz, 1979)III/218 : ELODIE archive (Prugniel+, 2001)V/133 : Kepler Input Catalog (Kepler Mission Team, 2009)V/156 : LAMOST DR7 catalogs (Luo+, 2019)IV/39 : TESS Input Catalog version 8.2 (TIC v8.2) (Paegert+, 2021)J/AJ/106/2096 : Limb-darkening coefficients in binaries (Van Hamme 1993)J/MNRAS/371/703 : MILES library of empirical spectra (Sanchez-Blazquez+, 2006)J/A+A/531/A165 : MILES atmospheric parameters (Prugniel+, 2011)J/AJ/141/83 : Kepler Mission.
