The ARAUCARIA project. Discovery of Cepheid Variables in NGC 300 from a Wide-Field Imaging Survey
G. Pietrzy{Å}ski, W. Gieren, P. Fouque +1
Based on observations of NGC 300, obtained with the Wide-Field Camera at the 2.2 m ESO/MPI telescope during 29 nights spread over a 5.3 month interval, 117 Cepheids and 12 Cepheid…
The Brown-dwarf Atmosphere Monitoring (BAM) Project II: Multi-epoch monitoring of extremely cool brown dwarfs
A. Rajan, J. Patience, P. A. Wilson +6
With the discovery of Y dwarfs by the WISE mission, the population of field brown dwarfs now extends to objects with temperatures comparable to those of Solar System planets. To in…
Searching for the secondary eclipse of CoRoT-Exo-2b and its transit timing variations
R. Alonso, S. Aigrain, F. Pont +2
With more than 80 transits observed in the CoRoT light curve with a cadence of 32 s, CoRoT-Exo-2b provides an excellent case to search for the secondary eclipse of the planet, with…
HST hot-Jupiter transmission spectral survey: Haze in the atmosphere of WASP-6b
N. Nikolov, D. K. Sing, A. S. Burrows +14
We report Hubble Space Telescope (HST) optical to near-infrared transmission spectroscopy of the hot Jupiter WASP-6b, measured with the Space Telescope Imaging Spectrograph (STIS)…
A Gaussian process framework for modelling instrumental systematics: application to transmission spectroscopy
N. P. Gibson, S. Aigrain, S. Roberts +3
Transmission spectroscopy, which consists of measuring the wavelength-dependent absorption of starlight by a planet's atmosphere during a transit, is a powerful probe of atmospheri…
ELODIE metallicity-biased search for transiting Hot Jupiters V. An intermediate-period Jovian planet orbiting HD45652
N. C. Santos, S. Udry, F. Bouchy +20
We present the detection of a 0.47 Jupiter mass planet in a 44-day period eccentric trajectory (e=0.39) orbiting the metal-rich star HD45652. This planet, the seventh giant planet…
