Scientific paper

We present new transits of targets TrES-1b, TrES-3b, XO-2b, and GJ-1214b, observed with IRTF-MORIS. The radius ratio we found for TrES-1b in Sloan r’ is 0.131190 +/- 0.000057, which differs by 7 sigma from the Winn et al. (2007) value in z'. A possible cause for this inconsistency is wavelength variation by depth. The other parameters found for TrES-1b were consistent with the Winn et al. (2007) values. The timing for TrES-1b may indicate the need for a new ephemeris. The orbital and planetary parameters found for TrES-3b were consistent with previous values, which can be attributed to good observational conditions and a bright companion star. Likewise, the values found for XO-2b deviated very little from previous literature. Both TrES-3b and XO-2b demonstrated consistent timing values. Due to poor conditions and a lack of good comparison stars within the field of view, the parameter values for the radius ratio, inclination, and orbital distance, found for GJ-1214b are not reliable. The timing values, while still suspect, suggest consistency with the current ephemeris. This work is supported in part by the NSF REU and DOD ASSURE programs under NSF grant no. 0754568 and by the Smithsonian Institution.
