THE MID-INFRARED SPECTRUM OF THE TRANSITING EXOPLANET HD 209458b
We report the spectroscopic detection of mid-infrared emission from the transiting exoplanet HD 209458b. Using archive data taken with the Spitzer IRS instrument, we have determined the spectrum of HD 209458b between 7.46 and 15.25 m. We have used two independent methods to determine the planet spectrum, one differential in wavelength and one absolute, and find the results are in good agreement...
متن کاملTransiting Exoplanet Survey Satellite
The Transiting Exoplanet Survey Satellite (TESS) will search for planets transiting bright and nearby stars. TESS has been selected by NASA for launch in 2017 as an Astrophysics Explorer mission. The spacecraft will be placed into a highly elliptical 13.7-day orbit around the Earth. During its 2-year mission, TESS will employ four wide-field optical charge-coupled device cameras to monitor at l...
متن کاملA Smaller Radius for the Transiting Exoplanet
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...
متن کاملPhotometric Precision for the Transiting Exoplanet
We seek to fully characterize all noise contributions along the CCD and electronics signal path specific to the equipment to be used on board the TESS all-sky space observatory. We adjust physical variables in such a way as to minimize this noise and achieve a photometric precision limited in large part by shot noise. Ultimately, the goal is to demonstrate in the lab, by analyzing photon data g...
متن کاملThe transmission spectrum of Earth-size transiting planets
A variety of terrestrial planets with different physical parameters and exotic atmospheres might plausibly exist outside our Solar System, waiting to be detected by the next generation of space-exploration missions. Some of these planets might transit their parent star. We present here the first study of atmospheric signatures of transiting Earth-size exoplanets. We focus on a limited number of...
