We report on the current status of the University of New South Wales Extrasolar Planet Search project, giving details of the methods we use to obtain millimagnitude precision photometry using the 0.5-m Automated Patrol Telescope. We use a novel observing technique to optimally broaden the point spread function and thus largely eliminate photometric noise due to intrapixel sensitivity variations on the CCD. We have observed eight crowded Galactic fields using this technique during 2003 and 2004… Expand
The University of New South Wales Extrasolar Planet Search: a catalogue of variable stars from fields observed between 2004 and 2007
We present a new catalogue of variable stars compiled from data taken for the University of New South Wales Extrasolar Planet Search. From 2004 October to 2007 May, 25 target fields were eachExpand
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 withExpand
We present the results of a deep, wide-field search for transiting hot Jupiter (HJ) planets in the globular cluster ? Centauri. As a result of a 25 night observing run with the ANU 40 inch (1 m)Expand
Survey for Transiting Extrasolar Planets in Stellar Systems. IV. Variables in the Field of NGC 1245
The Survey for Transiting Extrasolar Planets in Stellar Systems (STEPSS) project is a search for planetary transits in open clusters. In this paper we analyze the STEPSS observations of the openExpand
Discovery of four W UMa type eclipsing binaries in the field of open cluster ASCC 5
We carried out time-series photometric observations in the Rc -band of the young, poorly studied open cluster ASCC 5 during November and December, 2012, to search for magnetically active stars, andExpand
Outcome of Six Candidate Transiting Planets from a TrES Field in Andromeda
Driven by the incomplete understanding of the formation of gas giant extrasolar planets and of their mass-radius relationship, several ground-based, wide-field photometric campaigns are searching theExpand
Looking for Giant Earths in the HD 209458 System: A Search for Transits in MOST Space-based Photometry
We have made a comprehensive transit search for exoplanets down to 1.5-2 Earth radii in the HD 189733 system, based on 21 days of nearly uninterrupted broadband optical photometry obtained with theExpand
Observing bright stars and their planets from the Earth and from space
The discovery and characterization of extrasolar planets is a leading frontier of science, which is limited by our ability to extract real astrophysical signals masked by systematic noise. In thisExpand
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 transitExpand
Several photometric surveys for short-period transiting giant planets have targeted a number of open clusters, but no convincing detections have been reported. Although each individual surveyExpand


The HARPS search for southern extra-solar planets. I. HD 330075 b: A new "hot Jupiter"
We report on the first extra-solar planet discovered with the brand new HARPS instrument. The planet is a typical "hot Jupiter" with m2 sini = 0.62 MJup and an orbital period of 3.39 days, but fromExpand
Wide‐Field Millimagnitude Photometry with the HAT: A Tool for Extrasolar Planet Detection
ABSTRACT We discuss the system requirements for obtaining millimagnitude photometric precision over a wide field using small‐aperture, short focal length telescope systems such as those beingExpand
Planets in Stellar Clusters Extensive Search. II. Discovery of 57 Variables in the Cluster NGC 2158 with Millimagnitude Image Subtraction Photometry
We have undertaken a long-term project, Planets in Stellar Clusters Extensive Search (PISCES), to search for transiting planets in open clusters. NGC 2158 is one of the targets we have chosen—anExpand
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 theExpand
An Absence of Hot Jupiter Planets in 47 Tucanae: Results of a Wide-Field Transit Search
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 globularExpand
Four New Planets Orbiting Metal-enriched Stars*
We report the detection of four new extrasolar planets from the Anglo-Australian Planet Search orbiting the metal-enriched stars HD 73526, HD 76700, HD 30177, and HD 2039. The planetary companion ofExpand
Searching for Planetary Transits in Galactic Open Clusters: EXPLORE/OC
Open clusters potentially provide an ideal environment for the search for transiting extrasolar planets, since they feature a relatively large number of stars of the same known age and metallicity atExpand
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.Expand
Transit Detectability of Ring Systems around Extrasolar Giant Planets
We investigate whether rings around extrasolar planets could be detected from those planets' transit light curves. To this end, we develop a basic theoretical framework for calculating andExpand
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.
