This paper presents the results of a comprehensive wide-field search for transiting "hot Jupiter" planets (gas giant planets with an orbital period in the range 1 day ≤ P ≤ 16 days) in the globular cluster 47 Tuc. Motivated by the detection of the transit in HD 209458 and the apparent lack of planetary detections in the core of 47 Tuc by Gilliland and coworkers, this work further addresses the question of giant planet frequency in 47 Tuc by observing from the ground a 52′ × 52′ field centered…

The Frequency of Large-Radius Hot and Very Hot Jupiters in ω Centauri
We present the results of a deep, wide-field search for transiting hot Jupiter (HJ) planets in the globular cluster ω Centauri. As a result of a 25 night observing run with the ANU 40 inch (1 m)
Upper limits on the hot Jupiter fraction in the field of NGC 7789
We describe a method of estimating the abundance of short-period extra-solar planets based on the results of a photometric survey for planetary transits. We apply the method to a 21-night survey with
The tidal evolution of hot Jupiters may change the efficiency of transit surveys of stellar clusters. The orbital decay that hot Jupiters suffer may result in their destruction, leaving fewer
An HST search for planets in the lower main sequence of the globular cluster NGC 6397
Searches for planetary transits carried out in open and globular clusters have to date yielded only a handful of weak, unconfirmed candidates. These results have been interpreted as either being
Survey for Transiting Extrasolar Planets in Stellar Systems. III. A Limit on the Fraction of Stars with Planets in the Open Cluster NGC 1245
We analyze a 19 night photometric search for transiting extrasolar planets in the open cluster NGC 1245. An automated transit search algorithm with quantitative selection criteria finds six transit
We present the results of a deep, wide-field transit survey targeting “Hot Jupiter” planets in the Lupus region of the Galactic plane conducted over 53 nights concentrated in two epochs separated by
A new search for planet transits in NGC 6791
Context. Searching for planets in open clusters allows us to study the effects of dynamical environment on planet formation and evolution. Aims. Considering the strong dependence of planet frequency
A Photometric Search for Planets in the Open Cluster NGC 7086
In an attempt to discover short-period, Jupiter-mass planets orbiting solar-type stars in open clusters, we searched for planetary transits in the populous and relatively unstudied open cluster NGC
Planets in Stellar Clusters Extensive Search. III. A Search for Transiting Planets in the Metal-rich Open Cluster NGC 6791
We have undertaken a long-term project, Planets in Stellar Clusters Extensive Search (PISCES), to search for transiting planets in open clusters. In this paper we present the results for NGC 6791, a
Hot Jupiters Driven by High-eccentricity Migration in Globular Clusters
Hot Jupiters (HJs) are short-period giant planets that are observed around of solar-type field stars. One possible formation scenario for HJs is high-eccentricity (high-e) migration, in which the


A Lack of Planets in 47 Tucanae from a Hubble Space Telescope Search
We report results from a large Hubble Space Telescope project to observe a significant (~34,000) ensemble of main-sequence stars in the globular cluster 47 Tucanae with a goal of defining the
A Comprehensive Catalog of Variable Stars in the Field of 47 Tucanae
We present the results of a comprehensive search for stellar variability in the globular cluster 47 Tucanae. Using the Mount Stromlo 40 inch (1 m) telescope at Siding Spring Observatory and a
TrES-1: The Transiting Planet of a Bright K0 V Star
We report the detection of a transiting Jupiter-sized planet orbiting a relatively bright (V = 11.79) K0 V star. We detected the transit light-curve signature in the course of the TrES multisite
A search for planets in the old open cluster NGC 6791
We describe the results of a search for transit-like events caused by giant planets occulting stars in the old, metal-rich open cluster NGC 6791 based on BVI -colour photometry from eight nights of
On the Radii of Close-in Giant Planets
It is found that HD 209458b must be a hydrogen-rich gas giant and the large radius of a close-in gas giant is not due to the thermal expansion of its atmosphere but to the high residual entropy that remains throughout its bulk by dint of its early proximity to a luminous primary.
Detection of Planetary Transits Across a Sun-like Star
High-precision, high-cadence photometric measurements of the star HD 209458 are reported, which is known from radial velocity measurements to have a planetary-mass companion in a close orbit and the detailed shape of the transit curve due to both the limb darkening of thestar and the finite size of the planet is clearly evident.
A Transiting “51 Peg-like” Planet
Doppler measurements from Keck exhibit a sinusoidal periodicity in the velocities of the G0 dwarf HD 209458, having a semiamplitude of 81 m s-1 and a period of 3.5239 days, which is indicative of a
An extrasolar planet that transits the disk of its parent star
Planets orbiting other stars could in principle be found through the periodic dimming of starlight as a planet moves across—or ‘transits’—the line of sight between the observer and the star.
Mining the Metal-rich Stars for Planets
We examine the correlation between stellar metallicity and the presence of short-period planets. It appears that approximately 1% of dwarf stars in the solar neighborhood harbor short-period planets
The metal-rich nature of stars with planets
With the goal of confirming the metallicity "excess" present in stars with planetary-mass companions, we present in this paper a high-precision spectroscopic study of a sample of dwarfs included in
