Both TICs 167692429 and 220397947 were previously unknown eclipsing binaries, and the presence of a third companion star was inferred from eclipse timing variations exhibiting signatures of strong third-body perturbations and, in the first system, also from eclipse depth variations. We carried out comprehensive analyses, including the simultaneous photodynamical modelling of TESS and archival ground-based WASP light curves, as well as eclipse timing variation curves. Also, for the first time, we included in the simultaneous fits multiple star spectral energy distribution data and theoretical PARSEC stellar isochrones, taking into account Gaia DR2 parallaxes and catalogued metallicities. We find that both systems have twin F-star binaries and a lower mass tertiary star. In the TIC 167692429 system, the inner binary is moderately inclined (i_mut_=27{deg}) with respect to the outer orbit, and the binary versus outer (triple) orbital periods are 10.3 versus 331d, respectively. The mutually inclined orbits cause a driven precession of the binary orbital plane that leads to the disappearance of binary eclipses for long intervals. In the case of TIC 220397947, the two orbital planes are more nearly aligned and the inner versus outer orbital periods are 3.5 and 77d, respectively. In the absence of radial velocity observations, we were unable to calculate highly accurate masses and ages for the two systems. According to stellar isochrones TIC 167692429 might be either a pre-main sequence (MS) or an older post-MS system. In the case of TIC 220397947, our solution prefers a young pre-MS scenario.2020MNRAS.493.5005Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/493/5005CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIV/39 : TESS Input Catalog version 8.2 (TIC v8.2) (Paegert+, 2021)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)II/328 : AllWISE Data Release (Cutri+ 2013)II/336 : AAVSO Photometric All Sky Survey (APASS) DR9 (Henden+, 2016)I/259 : The Tycho-2 Catalogue (Hog+ 2000)I/345 : Gaia DR2 (Gaia Collaboration, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/493/5005https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/493/5005http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/493/5005https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/493/5005https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/493/5005http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/493/5005GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/493/5005/table1 (Main characteristics of TICs 167692429 and 220397947)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/493/5005/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/493/5005/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/493/5005/table1?GETtext/xml+votable180.050000true102.71605-63.431044440.0055555555555555566/33929 375613.830199579824256e-20 5.101838343667421e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/493/5005?format=asciiOpticalInfrareddefaultJ/MNRAS/493/5005/table1Main characteristics of TICs 167692429 and 220397947recnoRecord number assigned by the VizieR team.
