cds-question@unistra.freclipsing-binary-starsvisible-astronomymedium-band-photometryAccurate uvby light curves of the southern, detached, double-lined eclipsing binary V539 Ara (HR 6622A, HD 161783, V=5.71mag , B3V+B4V, P=3.17d) are presented. They contain 1409 observations in each colour, collected 1982-1984. Typical mean errors are 0.003-0.004mag. Observations for 8 additional times of minima from 1985-1994 are included. The secondary component belongs to the group of slowly pulsating B (or SPB) stars. An analysis of V539 Ara based on the new photometry and the spectroscopic orbit by Andersen (1983A&A...118..255A) is published separately (Clausen 1995).1996A&AS..115..315Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/115/315CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/101/563 : GG Lupi ubvy photometry (Clausen+ 1993)J/A+AS/109/425 : AO Velorum ubvy photometry (Clausen+ 1995)J/A+AS/112/123 : LZ Centauri ubvy photometry (Vaz+ 1995)J/A+AS/125/471 : Light curves of the triple system V906 Sco (Vaz+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/115/315https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/115/315http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/115/315https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/115/315https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/115/315http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/115/315GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+AS/115/315/table2Light curves V539 Ara - HR6614 in the 1982-1984 instrumental system (uvby)recnoRecord number assigned by the VizieR team.
