cds-question@unistra.frsolar-system-planetsinfrared-photometryCurrently the only technique sensitive to Earth mass planets around nearby stars (that are too close for microlensing) is the monitoring of the transit time variations of the transiting extrasolar planets. We search for additional planets in the systems of the hot Neptune GJ 436b, and the hot-Jupiter XO-1b, using high cadence observations in the J and KS bands. New high-precision transit timing measurements are reported: GJ 436b Tc=2454238.47898+/-0.00046HJD; XO-1b Tc(A)=2454218.83331+/-0.00114HJD, Tc(B)=2454222.77539+/-0.00036HJD, Tc(C)=2454222.77597+/-0.00039HJD, Tc(D)=2454226.71769+/-0.00034HJD, and they were used to derive new ephemeris. We also determined depths for these transits. No statistically significant timing deviations were detected. We demonstrate that the high cadence ground based near-infrared observations are successful in constraining the mean transit time to 30s, and are a viable alternative to space missions.2009A&A...507..481Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/507/481CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/471/L51 : Spitzer obs. of the hot Neptune GJ 436b (Gillon+, 2007)J/A+A/475/1125 : Characterization of the hot Neptune GJ 436b (Demory+, 2007)J/A+A/486/1039 : HST transit light curve for GJ436b (Bean+, 2008)J/MNRAS/384/1097 : SuperWASP-North extrasolar planet candidates (Kane+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/507/481https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/507/481http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/507/481https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/507/481https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/507/481http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/507/481GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfrareddefaultJ/A+A/507/481/table2aGJ 436b Transit light curvesTargetTarget namemeta.id;meta.maincharFluxNormalized fluxphot.flux;arith.ratiodoublerecnoRecord number assigned by the VizieR team.
