WASP-52b, WASP-58b, WASP-59b, and WASP-60b: Four new transiting close-in giant planets

The spin-orbit angles of the transiting exoplanets WASP-1b, WASP-24b, WASP-38b and HAT-P-8b from Rossiter-McLaughlin observations

We present observations of the Rossiter-McLaughlin effect for the transiting exoplanet systems WASP-1, WASP-24, WASP-38 and HAT-P-8, and deduce the orientations of the planetary orbits with respect to the host stars’ rotation axes. The planets WASP-24b, WASP-38b and HAT-P-8b appear to move in prograde orbits and be well aligned, having sky-projected spin orbit angles consistent with zero: λ = −...

A SMALLER RADIUS FOR THE TRANSITING EXOPLANET WASP-10b

We present photometry of WASP-10 during a transit of its short–period Jovian planet. We employed the novel PSF–shaping capabilities of the OPTIC camera mounted on the UH 2.2m telescope to achieve a photometric precision of 4.7 × 10 per 1.3 min sample. With this new light curve, in conjunction with stellar evolutionary models, we improve on existing measurements of the planetary, stellar and orb...

SPITZER SECONDARY ECLIPSE DEPTHS WITH MULTIPLE INTRAPIXEL SENSITIVITY CORRECTION METHODS OBSERVATIONS OF WASP-13b, WASP-15b, WASP-16b, WASP-62b, AND HAT-P-22b

We measure the 4.5 μm thermal emission of five transiting hot Jupiters, WASP-13b, WASP-15b, WASP-16b, WASP-62b, and HAT-P-22b using channel 2 of the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. Significant intrapixel sensitivity variations in Spitzer IRAC data require careful correction in order to achieve precision on the order of several hundred parts per million (ppm) for the...

Photometric follow - up of the transiting planet around WASP - 1

We report on photometric follow-up of the recently discovered transiting planet WASP-1b. We observed two transits with the Wise Observatory 1m telescope, and used a variant of the EBOP code simultaneously with the SysRem detrending code for fitting the light curve. Assuming a stellar mass of 1.15M⊙ we derived a planetary radius of Rp = 1.398± 0.076RJ and mass of Mp = 0.867±0.073MJ. We also deri...
