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… 

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 each

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

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 open

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)

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, and

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 the

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

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 about 2 Earth radii in the HD 209458 system, based on nearly uninterrupted broadband optical photometry obtained with the MOST

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 this


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 survey



Wide‐Field Millimagnitude Photometry with the HAT: A Tool for Extrasolar Planet Detection

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 being developed by a

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—an

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

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 globular

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 at

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.

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 of

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 and

Infrared Observations during the Secondary Eclipse of HD 209458b. I. 3.6 Micron Occultation Spectroscopy Using the Very Large Telescope

We search for an infrared signature of the transiting extrasolar planet HD 209458b during secondary eclipse. Our method, which we call "occultation spectroscopy," searches for the disappearance and

Theoretical Transmission Spectra during Extrasolar Giant Planet Transits

The recent transit observation of HD 209458 b—an extrasolar planet orbiting a Sun-like star—confirmed that it is a gas giant and determined that its orbital inclination is 85°. This inclination makes
