cds-question@unistra.frmultiple-starssolar-system-planetsphotometryWe present 11 high-precision photometric transit observations of the transiting super-Earth planet GJ 1214 b. Combining these data with observations from other authors, we investigate the ephemeris for possible signs of transit timing variations (TTVs) using a Bayesian approach. The observations were obtained using telescope-defocusing techniques, and achieve a high precision with random errors in the photometry as low as 1 mmag per point. To investigate the possibility of TTVs in the light curve, we calculate the overall probability of a TTV signal using Bayesian methods.2013A&A...549A..10Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/549/A10CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/549/A10https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/549/A10http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/549/A10https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/549/A10https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/549/A10http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/549/A10GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/549/A10/table1Log of the transit observations of GJ 1214 for this workScatScattermagstat.errordoubleApAperture sizes (1)phys.angSize;instr.fovcharrecnoRecord number assigned by the VizieR team.
