cds-question@unistra.frmultiple-starssolar-system-planetsvisible-astronomysloan-photometryRepeated observations of exoplanet transits allow us to refine the planetary parameters and probe them for any time dependent variations. In particular deviations of the period from a strictly linear ephemeris, transit timing variations (TTVs), can indicate the presence of additional bodies in the planetary system. Aims: Our goal was to reexamine the largely unstudied OGLE2-TR-L9 system with high cadence, multi-color photometry in order to refine the planetary parameters and probe the system for TTVs. From our analysis we find that the semi-major axis and the inclination differ from the previously published values. With the newly observed transits, we were able to refine the ephemeris to 2454492.80008(+/-0.00014) +2.48553417(+/-6.4)x10^-7^E. The newly derived parameters are a=0.0418(+/-0.0015)AU, r_p_=1.67(+/-0.05) R_j_, and inc=82.47{deg}(+/-0.12), differing significantly in a and inc from the previously published values. Within our data, we find indications for TTVs.2010A&A...522A..29Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/522/A29CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/522/A29https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/522/A29http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/522/A29https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/522/A29https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/522/A29http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/522/A29GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/522/A29/tablegg' datarecnoRecord number assigned by the VizieR team.
