Abstract (from CDS):

Currently 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. We search for additional planets in the systems of the hot Neptune GJ436b, and the hot-Jupiter XO-1b, using high cadence observations in the J and KS bands. New high-precision transit timing measurements are reported: GJ436b TC=2454238.47898±0.00046 HJD; XO-1b TC(A)=2454218.83331±0.00114 HJD, TC(B)=2454222.77539±0.00036 HJD, TC(C)=2454222.77597±0.00039 HJD, TC(D)=2454226.71769±0.00034 HJD, and they were used to derive new ephemeris values. 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.
