Characterizing Long-Period Transiting Planets Observed by Kepler
Kepler will monitor a sufficient number of stars that it is likely to detect single transits of planets with periods longer than the mission lifetime. We show that by combining the exquisite Kepler photometry of such transits with precise radial velocity observations taken over a reasonable timescale (∼ 6 months) after the transits, and assuming circular orbits, it is possible to estimate the p...
متن کاملA Study of the Shortest-period Planets Found with Kepler
We present the results of a survey aimed at discovering and studying transiting planets with orbital periods shorter than one day (ultra–short-period, or USP, planets), using data from the Kepler spacecraft. We computed Fourier transforms of the photometric time series for all 200,000 target stars, and detected transit signals based on the presence of regularly spaced sharp peaks in the Fourier...
متن کاملBenefits of Ground-Based Photometric Follow-Up for Transiting Extrasolar Planets Discovered with Kepler and CoRoT
Currently, over forty transiting planets have been discovered by ground-based photometric surveys, and space-based missions like Kepler and CoRoT are expected to detect hundreds more. Follow-up photometric observations from the ground will play an important role in constraining both orbital and physical parameters for newly discovered planets, especially those with small radii (Rp . 4 R⊕) and/o...
متن کاملKepler-9: a system of multiple planets transiting a Sun-like star, confirmed by timing variations.
The Kepler spacecraft is monitoring more than 150,000 stars for evidence of planets transiting those stars. We report the detection of two Saturn-size planets that transit the same Sun-like star, based on 7 months of Kepler observations. Their 19.2- and 38.9-day periods are presently increasing and decreasing at respective average rates of 4 and 39 minutes per orbit; in addition, the transit ti...
متن کاملTransiting Planet Simulations from the All Sky Extrasolar Planets Survey
Many of the planets discovered via the radial velocity technique are hot Jupiters in 3–5 day orbits with ∼ 10% chance of transiting their parent star. However, radial velocity surveys for extra-solar planets generally require substantial amounts of large telescope time in order to monitor a sufficient number of stars due to the single-object capabilities of the spectrograph. A multi-object Dopp...
