cds-question@unistra.frpre-main-sequence-starsinfrared-photometryvisible-astronomybroad-band-photometryWe have monitored the photometric, spectroscopic and polarimetric variations of the classical T Tauri star (CTTS) AA Tau over a period of a month. The light curve consists of more than 260 measurements in each of the B and V-bands over a continuous time period of 30 days and more than 180 measurements in the R and I-bands. This provides unprecedented detail of the photometric variations of a CTTS on timescales ranging from hours to weeks.1999A&A...349..619Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/349/619CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/409/169 : UBVRI light curves of AA Tau in 1999 (Bouvier+, 2003)Table 1: Journal of ObservationsTable 2: JHK photometryhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/349/619https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/349/619http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/349/619https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/349/619https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/349/619http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/349/619GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/349/619/ubvriUBVRI light curves of AA TaurecnoRecord number assigned by the VizieR team.
