cds-question@unistra.frmultiple-starssolar-system-planetsinfrared-photometryvisible-astronomyphotometryWe present the first photometric follow-up of the transiting planet HAT-P-16 b, and new photometric observations of WASP-21 b, obtained simultaneously with two medium-class telescopes located in different countries, using the telescope defocussing technique. We modeled these and other published data in order to estimate the physical parameters of the two planetary systems.2013A&A...557A..30Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/557/A30CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/720/1118 : HAT-P-16 i-band photometry (Buchhave+, 2010)J/A+A/519/A98 : WASP-21b transit (Bouchy+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/557/A30https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/557/A30http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/557/A30https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/557/A30https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/557/A30http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/557/A30GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/557/A30/table1Observing log for the two transiting extrasolar planet systemsLCtransit curvemeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
