cds-question@unistra.freclipsing-binary-starsinfrared-photometryvisible-astronomybroad-band-photometryA study of late-type low-mass eclipsing binaries provides us with important information about the most common stars in the Universe. We obtain the first light curves and perform period analyses of two neglected eclipsing binaries GK Boo and AE For to reveal their basic physical properties. We performed both a period analysis of the times of the minima and a BVR light curve analysis. Many new times of minima for both the systems were derived and collected from the data obtained by automatic and robotic telescopes. This allowed us to study the long-term period changes in these systems for the first time. From the light curve analysis, we derived the first rough estimates of the physical properties of these systems.2012A&A...537A.109Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/537/A109CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/537/A109https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/537/A109http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/537/A109https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/537/A109https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/537/A109http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/537/A109GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/537/A109/photBVR photometry of AE For and GK BoorecnoRecord number assigned by the VizieR team.
