cds-question@unistra.freclipsing-binary-starsinfrared-photometryvisible-astronomybroad-band-photometryWe analyze new multicolor light curves for four close late-type binaries: HS Aqr, EG Cep, VW LMi, and DU Boo, in order to determine the orbital and physical parameters of the systems and estimate the distances. The analysis is done using the modeling code of G. Djurasevic, and is based on up-to-date measurements of spectroscopic elements. All four systems have complex, asymmetric light curves that we model by including bright or dark spots on one or both components. Our findings indicate that HS Aqr and EG Cep are in semi-detached, while VW LMi and DU Boo are in overcontact configurations.2013AJ....145...80Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/145/80CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/vsx : AAVSO International Variable Star Index VSX (Watson+, 2006-2014)B/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2013)V/119 : Catalogue of field contact binary stars (Pribulla+, 2003)II/233 : Tycho variables stars (Piquard 2001)V/120 : Catalog of early-type contact binaries (Bondarenko+, 1996)J/AN/334/860 : Catalogue of eclipsing variables.
