Some of the first results are reported from RISE – a new fast camera mounted on the Liverpool Telescope primarily designed to obtain high time-resolution light curves of transiting extrasolar planets for the purpose of transit timing. A full and partial transit of WASP-3 are presented, and a Markov-Chain Monte Carlo analysis is used to update the parameters from the discovery paper. This results in a planetary radius of $1.29^{\rm +0.05}_{-0.12}$ RJ and therefore a density of $0.82^{+0.14}_{-0…

High‐precision transit observations of the exoplanet WASP‐13b with the RISE instrument

WASP-13b is a sub-Jupiter mass exoplanet orbiting a G1V type star with a period of 4.35 d. The current uncertainty in its impact parameter (0 < b < 0.46) results in poorly defined stellar and

A lower mass for the exoplanet WASP‐21b

We present high-precision transit observations of the exoplanet WASP-21b, obtained with the Rapid Imager to Search for Exoplanets instrument mounted on the 2.0-m Liverpool Telescope. A transit model


We present nine newly observed transits of TrES-3, taken as part of a transit timing program using the RISE instrument on the Liverpool Telescope. A Markov-Chain Monte Carlo analysis was used to

A transit timing analysis of seven RISE light curves of the exoplanet system HAT-P-3

We present seven light curves of the exoplanet system HAT-P-3, taken as part of a transit timing programme using the rapid imager to search for exoplanets instrument on the Liverpool Telescope. The

WASP-38b: a transiting exoplanet in an eccentric, 6.87d period orbit

Aims. We report the discovery of WASP-38b, a long period transiting planet in an eccentric 6.871815 day orbit. The transit epoch is 2455335.92050�0.00074 (HJD) and the transit duration is 4.663

Exoplanetary system WASP-3 : measurement of the projected spin-orbit angle and evidence for stellar activity

In this thesis, I present new spectroscopic and photometric observations of WASP-3, a transiting extrasolar planetary system. From spectra obtained during two transits, I use the Rossiter-McLaughlin

WASP-4b transit observations with GROND

Context. Ground-based simultaneous multiband transit observations allow an accurate system parameter determination and may lead to the detection and characterization of additional bodies via the

Transit timing variations in WASP-10b induced by stellar activity

The hot-Jupiter WASP-10b was reported by Maciejewski et al. to show transit timing variations (TTVs) with an amplitude of similar to 3.5 min. These authors proposed that the observed TTVs were caused

The spin–orbit alignment of the transiting exoplanet WASP-3b from Rossiter–McLaughlin observations

We present an observation of the Rossiter-McLaughlin effect for the planetary system WASP-3. Radial velocity measurements were made during transit using the SOPHIE spectrograph at the 1.93-m

Ground-based detection of thermal emission from the exoplanet WASP-19b ?

An occultation of the newly discovered hot Jupiter system WASP-19 is observed with the High Acuity Wide-field K-band Imager instrument on the VLT in order to measure thermal emission from the planet's dayside at ∼2μm, indicating that the planet shows poor redistribution of heat to the night side, consistent with models of highly irradiated planets.



WASP-3b: a strongly irradiated transiting gas-giant planet

The proximity and relative temperature of the host star suggests that WASP-3b is one of the hottest exoplanets known, and thus has the potential to place stringent constraints on exoplanet atmospheric models.

Efficient identification of exoplanetary transit candidates from SuperWASP light curves

Transiting extrasolar planets constitute only a small fraction of the range of stellar systems found to display periodic, shallow dimmings in wide-field surveys employing small-aperture A camera

The transit light curve project. I. Four consecutive transits of the exoplanet XO-1b

We present RIz photometry of four consecutive transits of the newly discovered exoplanet XO-1b. We improve on the estimates of the transit parameters, finding the planetary radius to be RP = 1.184RJ,

Detection of transits of the nearby hot Neptune GJ 436 b

This Letter reports on the photometric detection of transits of the Neptune-mass planet orbiting the nearby M-dwarf star GJ 436. It is by far the closest, smallest, and least massive transiting

High accuracy transit photometry of the planet OGLE-TR-113b with a new deconvolution-based method

A high accuracy photometry algorithm is needed to take full advantage of the potential of the transit method for the characterization of exoplanets, especially in deep crowded fields. It has to

An analysis of the transit times of tres-1b

The presence of a second planet in a known, transiting-planet system will cause the time between transits to vary. These variations can be used to constrain the orbital elements and mass of the

The effect of red noise on planetary transit detection

Since the discovery of short-period exoplanets a decade ago, photometric surveys have been recognized as a feasible method to detect transiting hot Jupiters. Many transit surveys are now underway,

A Unique Solution of Planet and Star Parameters from an Extrasolar Planet Transit Light Curve

There is a unique solution of the planet and star parameters from a planet transit light curve with two or more transits if the planet has a circular orbit and the light curve is observed in a

On detecting terrestrial planets with timing of giant planet transits

The transits of a distant star by a planet on a Keplerian orbit occur at time intervals exactly equal to the orbital period. If a second planet orbits the same star, the orbits are not Keplerian and
