High-precision Transit Photometry of OGLE-TR-10
We present B and I photometry of OGLE-TR-10 during transits of its giant planet. From our observations, we estimate the radius of the planet to be 1.16± 0.05 times the radius of Jupiter, assuming a stellar mass of M⋆ = 1.02 M⊙. This is smaller than previous estimates that were based on lower-precision data, and hence the planet is not as anomalous as was once believed. We provide updated determ...
متن کاملTechniques for Automated High-Precision Photometry of Sun-like Stars
Tennessee State University operates several Automatic Photoelectric Telescopes (APTs) located at Fairborn Observatory in the Patagonia Mountains of southern Arizona. The APTs are dedicated to photometric monitoring programs that would be difficult and expensive to accomplish without the advantages provided by automation. I describe the operation of two of the telescopes (0.75 and 0.80 m APTs) a...
متن کاملExoplanetsat: High Precision Photometry for Exoplanet Transit Detections in a 3u Cubesat
ExoplanetSat is a 3U CubeSat which will detect transiting “superEarth” exoplanets around bright, nearby sun-like stars. The ExoplanetSat prototype will focus on stars with low-mass planets (discovered by radial velocity planetfinding surveys)—planets which are not yet known to transit. No other current ground or space-based mission is capable of observing these systems, one star at at a time, o...
متن کاملHigh - precision photometry by telescope defocussing . VII . The ultra - short period planet WASP - 103 ⋆
We present 17 transit light curves of the ultra-short period planetary system WASP-103, a strong candidate for the detection of tidally-induced orbital decay. We use these to establish a high-precision reference epoch for transit timing studies. The time of the reference transit midpoint is now measured to an accuracy of 4.8 s, versus 67.4 s in the discovery paper, aiding future searches for or...
متن کاملHigh - precision photometry by telescope defocussing . II . The transiting planetary system WASP - 4 ⋆
We present and analyse light curves of four transits of the Southern hemisphere extrasolar planetary system WASP-4, obtained with a telescope defocussed so the radius of each point spread function was 17 (44 pixels). This approach minimises both random and systematic errors, allowing us to achieve scatters of between 0.60 and 0.88 mmag per observation over complete transit events. The light cur...
