We obtained double-lined radial velocities (RVs) from the time-series spectra and measured the effective temperature of the primary star as Teff,1=8560{+/-}118K. For the orbital period study, we collected all times of minima available for over the last 30yr. It was found that the eclipse timing variation of the system could be represented by a periodic oscillation of 17.6{+/-}0.3yr with a semiamplitude of 0.0041{+/-}0.0001day. The orbital and physical parameters were derived by simultaneously analyzing the TESS light and RV curves using the Wilson-Devinney (WD) binary star modeling code. The component masses and radii were showed over 3% precision: M1=2.67{+/-}0.08M{sun}, M2=0.43{+/-}0.01M{sun}, R1=2.01{+/-}0.02R{sun}, and R2=1.35{+/-}0.01R{sun}. Furthermore, multiple frequency analyses were performed for the light-curve residuals from the WD model. As a result, we detected 17 pressure-mode pulsations in the region of 40.15-52.37/day. The absolute dimensions and pulsation characteristics showed that the {delta}Sct pulsator was the more massive and hotter primary star of the EW Boo.2022AJ....164..216Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/164/216CatalogResearchIsServedByTAP VizieR generic servicerelated-toIV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)VI/120 : High-resolution synthetic stellar library (Coelho+, 2005)J/AJ/106/2096 : Limb-darkening coefficients in binaries (Van Hamme 1993)J/A+AS/141/371 : Low-mass stars evolut. tracks & isochrones (Girardi+, 2000)J/AcA/54/207 : Ephemerids of eclipsing binaries (Kreiner, 2004)J/AJ/129/2798 : AR Mon photometry and radial velocities (Williamon+, 2005)J/other/IBVS/5731 : Minima and maxima of 816 variables (Hubscher+, 2006)J/MNRAS/370/2013 : Catalogue of close binaries (Soydugan+, 2006)J/other/IBVS/5802 : Minima and maxima of 735 variables (Hubscher+, 2007)J/other/A+ARV/18.67 : Accurate masses and radii of normal stars (Torres+, 2010)J/PASP/124/411 : YY Cet UBV differential light curves (Williamon+, 2012)J/ApJS/208/9 : Intrinsic colors & temperatures PMS stars (Pecaut+, 2013)J/A+A/566/A98 : The Gaia Benchmark Stars - Library (Blanco-Cuaresma+, 2014)J/A+A/564/A133 : Gaia FGK benchmark stars; metallicity (Jofre+, 2014)J/AJ/148/37 : Long-term photometric behavior of V404 Lyr (Lee+, 2014)J/AJ/159/24 : Spectroscopy & Kepler data of EB star V404 Lyr (Lee+, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/164/216https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/164/216http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/164/216https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/164/216https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/164/216http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/164/216GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/AJ/164/216/table1Radial velocities of EW BooPhase[0.01/1] Phasetime.phasefloatrecnoRecord number assigned by the VizieR team.
