The MOG weak field approximation and observational test of galaxy rotation curves
As an alternative to dark matter models, MOdified Gravity (MOG) theory can compensate for dark matter by a covariant modification of Einstein gravity. The theory introduces two additional scalar
PHYSICAL PROPERTIES OF THE 0.94-DAY PERIOD TRANSITING PLANETARY SYSTEM WASP-18 ⁄
We present high-precision photometry of five consecutive transits of WASP-18, an extrasolar planetary system with one of the shortest orbital periods known. Through the use of telescope defocusing we
High-precision photometry by telescope defocussing. I. The transiting planetary system WASP-5
We present high-precision photometry of three transits of the extrasolar planetary system WASP-2, obtained by defocussing the telescope, and achieving point-to-point scatters of between 0.42 and 0.73
Physical properties, transmission and emission spectra of the WASP-19 planetary system from multi-colour photometry
We present new ground-based, multi-colour, broad-band photometric measurements of the physical parameters, transmission and emission spectra of the transiting extrasolar planet WASP-19b. The
Multifractal detrended fluctuation analysis of sunspot time series
We use multifractal detrended fluctuation analysis (MF-DFA), to study sunspot number fluctuations. The result of the MF-DFA shows that there are three crossover timescales in the fluctuation
The EROS2 search for microlensing events towards the spiral arms: the complete seven season results
the EROS-2 project has been designed to search for microlensing events towards any dense stellar field. The densest parts of the Galactic spiral arms have been monitored to maximize the microlensing
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 and
High-precision photometry by telescope defocusing – VII. The ultrashort period planet WASP-103
We present 17 transit light curves of the ultrashort period planetary system WASP-103, a strong candidate for the detection of tidally-induced orbital decay. We use these to establish a
High-precision photometry by telescope defocusing - IV. Confirmation of the huge radius of WASP-17 b
We present photometric observations of four transits in the WASP-17 planetary system, obtained using telescope defocusing techniques and with scatters reaching 0.5?mmag per point. Our revised orbital
Physical properties and transmission spectrum of the WASP-80 planetary system from multi-colour photometry
WASP-80 is one of only two systems known to contain a hot Jupiter which transits its M-dwarf host star. We present eight light curves of one transit event, obtained simultaneously using two
