cds-question@unistra.freclipsing-binary-starsinfrared-photometryvisible-astronomybroad-band-photometryWe present multicolor light curves for the W UMa-type eclipsing binary TU Boo for two epochs separated by 22 years. An analysis of the O-C diagram indicates the earlier observations took place right in the middle of a major period change, thus allowing for a unique study on mass transfer and period changes in this W UMa-type system. We compute model fits to our light curves, along with the only other published set, using the Wilson-Devinney program, and find temporally correlated changes in the size of the secondary component with anomalies in the O-C diagram. We investigate the cause of these changes and find support for the existence of rapid, large-scale mass transfer between the components.2008AJ....136.1089Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/136/1089CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/136/1089https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/136/1089http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/136/1089https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/136/1089https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/136/1089http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/136/1089GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/AJ/136/1089/table1a1983-1984 differential photometric datarecnoRecord number assigned by the VizieR team.
