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 being developed by a number of research groups to search for transiting extrasolar planets. We describe a Hungarian Automated Telescope (HAT) system, which attempts to meet these requirements. The attainable precision of HAT has been significantly improved by a technique in which the telescope is made to execute… Expand

High-precision photometry by telescope defocussing - II. The transiting planetary system WASP-4
We present high-precision photometry of two transit events of the extrasolar planetary system WASP-5, obtained with the Danish 1.54 m telescope at ESO La Silla. In order to minimise both random andExpand
The Hungarian-made Automated Telescope network (HATnet) is an ongoing project to detect transiting extra-solar planets using small aperture (11 cm diameter), robotic telescopes. In this paper weExpand
Precision multi-band photometry with a DSLR camera
Ground-based exoplanet surveys such as SuperWASP, HATNet and KELT have discovered close to two hundred transiting extrasolar planets in the past several years. The strategy of these surveys is toExpand
Small Telescope Exoplanet Transit Surveys: XO
The XO project aims at detecting transiting exoplanets around bright stars from the ground using small telescopes. The original configuration of XO (McCullough et al. 2005) has been changed andExpand
HATsouth: A global network of fully automated identical wide-field telescopes
HATSouth is the world's first network of automated and homogeneous telescopes that is capable of year-round 24 hr monitoring of positions over an entire hemisphere of the sky. The primary scientificExpand
Searching for transits in the WTS with difference imaging light curves
The Wide Field Camera Transit Survey is a pioneer program aimed to search for extra-solar planets in the near-infrared. The standard data reduction pipeline of the program uses aperture photometry toExpand
The University of New South Wales Extrasolar Planet Search: methods and first results from a field centred on NGC 6633
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 theExpand
Near-Infrared Monitoring of Ultracool Dwarfs: Prospects for Searching for Transiting Companions
ABSTRACT. Stars of late-M and L spectral types, collectively known as ultracool dwarfs (UCDs), may be excellent targets for searches for extrasolar planets. Owing to their small radii, the signalExpand
Synergies between exoplanet surveys and variable star research
With the discovery of the first transiting extrasolar planetary system back in 1999, a great number of projects started to hunt for other similar systems. Because the incidence rate of such systemsExpand
Finding the Brightest Galactic Bulge Microlensing Events with a Small Aperture Telescope and Image Subtraction
Following the suggestion of Gould and Depoy (1998) we investigate the feasibility of studying the brightest microlensing events towards the Galactic bulge using a small aperture (~10 cm) telescope.Expand


System Description and First Light Curves of the Hungarian Automated Telescope, an Autonomous Observatory for Variability Search
Having been operational at Kitt Peak for more than a year, the prototype (HAT-1) of the Hungarian Automated Telescope (HAT) has been used for an all-sky variability search of the northern hemisphere.Expand
Hubble Space Telescope Time-Series Photometry of the Transiting Planet of HD?209458
We have observed four transits of the planet of HD 209458 using the STIS spectrograph on the Hubble Space Telescope (HST). Summing the recorded counts over wavelength between 582 and 638 nm yields aExpand
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.

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
Detection of an Extrasolar Planet Atmosphere
We report high-precision spectrophotometric observations of four planetary transits of HD 209458, in the region of the sodium resonance doublet at 589.3 nm. We find that the photometric dimmingExpand
Using image area to control CCD systematic errors in spaceborne photometric and astrometric time-series measurements
The effect of some systematic errors for high-precision time-series spaceborne photometry and astrometry has been investigated with a CCD as the detector. The 'pixelization' of the images causesExpand
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 aExpand
An extended upper atmosphere around the extrasolar planet HD209458b
The detection of atomic hydrogen absorption in the stellar Lyman α line during three transits of HD209458b is reported, showing that this absorption should take place beyond the Roche limit and therefore can be understood in terms of escaping hydrogen atoms. Expand
