Hubble PanCET: An isothermal day-side atmosphere for the bloated gas-giant HAT-P-32Ab
N. Nikolov, D. K. Sing, J. Goyal +20
We present a thermal emission spectrum of the bloated hot Jupiter HAT-P-32Ab from a single eclipse observation made in spatial scan mode with the Wide Field Camera 3 (WFC3) aboard…
Marginalising instrument systematics in HST WFC3 transit lightcurves
H. R. Wakeford, D. K. Sing, T. Evans +2
Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) infrared observations at 1.1-1.7m probe primarily the HO absorption band at 1.4m, and has provided low resolution…
The optical transmission spectrum of the hot Jupiter HAT-P-32b: clouds explain the absence of broad spectral features?
N. P. Gibson, S. Aigrain, J. K. Barstow +3
We report Gemini-North GMOS observations of the inflated hot Jupiter HAT-P-32b during two primary transits. We simultaneously observed two comparison stars and used differential sp…
A Gemini ground-based transmission spectrum of WASP-29b: a featureless spectrum from 515 to 720nm
N. P. Gibson, S. Aigrain, J. K. Barstow +3
We report Gemini-South GMOS observations of the exoplanet system WASP-29 during primary transit as a test case for differential spectrophotometry. We use the multi-object spectrogr…
Probing the haze in the atmosphere of HD 189733b with HST/WFC3 transmission spectroscopy
N. P. Gibson, S. Aigrain, F. Pont +6
We present Hubble Space Telescope near-infrared transmission spectroscopy of the transiting exoplanet HD 189733b, using Wide Field Camera 3. This consists of time-series spectra of…
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…
Mapping the Shores of the Brown Dwarf Desert III: Young Moving Groups
Thomas M. Evans, Michael J. Ireland, Adam L. Kraus +6
We present the results of an aperture masking interferometry survey for substellar companions around 67 members of the young (~8-200Myr) nearby (~5-86pc) AB Doradus, Beta Pictoris,…
Transiting exoplanets from the CoRoT space mission. XVIII. CoRoT-18b: a massive hot jupiter on a prograde, nearly aligned orbit
G. Hebrard, T. M. Evans, R. Alonso +44
We report the detection of CoRoT-18b, a massive hot jupiter transiting in front of its host star with a period of 1.9000693 +/- 0.0000028 days. This planet was discovered thanks to…
Short period eclipsing binary candidates identified using SuperWASP
A. J. Norton, S. G. Payne, T. Evans +22
We present light curves and periods of 53 candidates for short period eclipsing binary stars identified by SuperWASP. These include 48 newly identified objects with periods <2x10^4…
