cds-question@unistra.freclipsing-binary-starsphotometryvisible-astronomyWe present Transiting Exoplanet Survey Satellite (TESS) light curve analysis of KZ Vir. The TESS observations of KZ Vir were published in a total of three Sectors. TESS observations show some features that could not be observed with ground-based telescopes before. We refined the light elements of the system by using the times of minima found in the literature and the times observed with TESS. The TESS light curve was analyzed with the Wilson-Devinney code including geometric and physical parameters of the components obtained using published radial velocity data. We confirmed for the first time that the system is essentially a detached type eclipsing binary and obtained masses and radii of the primary and the secondary components: M1=1.596+/-0.022M_{sun}_ , M2=1.319+/-0.019M_{sun}_ and R1=2.271+/-0.011R_{sun}_, R2=1.603+/-0.008R_{sun}_ , respectively. We find that the components of KZ Vir are located above or on the TAMS.2024AcA....74...27Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/74/27CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/74/27https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/74/27http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/74/27https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/74/27https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/74/27http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/74/27GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AcA/74/27/table1*The eclipse times of the KZ Vir systemrecnoRecord number assigned by the VizieR team.
