Absence of a Metallicity Effect for Ultra-short-period Planets
Ultra-short-period (USP) planets are a newly recognized class of planets with periods shorter than one day, and radii smaller than about 2 R⊕. It has been proposed that USP planets are the solid cores of hot Jupiters that lost their gaseous envelopes due to photo-evaporation or Roche lobe overflow. We test this hypothesis by asking whether USP planets are associated with metal-rich stars, as ha...
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 کاملLooking for Very Short-Period Planets with a Re-Purposed Kepler Mission
A re-purposed Kepler mission could continue the search for ∼Earth-sized planets in very short-period (≤ 1 day) orbits. Recent surveys of the Kepler data already available have revealed at least a dozen such planetary candidates, and a more complete and focused survey is likely to reveal more. Given the planets’ short orbital periods, building the requisite signal-to-noise to detect the candidat...
متن کاملCharacterizing 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 کاملThe Stability of Short-Period Extrasolar Giant Planets
A three-dimensional coupled thermosphere-ionosphere model for extrasolar giant planets (EXOTIM) has been developed. This is the first such model reported in the literature. This thesis contains an extensive description of the model and the methods adopted in modelling the different physical processes expected in the upper atmospheres and ionospheres of extrasolar giant planets. Modelling the up...
