Extrasolar planets and brown dwarfs around AF-type stars. X.The SOPHIE northern sample. Combining the SOPHIE and HARPS surveys to compute the close giant planet mass-period distribution around AF-type stars
S. Borgniet, A. -M. Lagrange, N. Meunier +31
The impact of the stellar mass on the giant planet properties is still to be fully understood. Main-Sequence (MS) stars more massive than the Sun remain relatively unexplored in ra…
A Search for Methane in the Atmosphere of GJ 1214b via GTC Narrow-Band Transmission Spectrophotometry
P. A. Wilson, K. D. Colón, D. K. Sing +11
We present narrow-band photometric measurements of the exoplanet GJ 1214b using the 10.4 m Gran Telescopio Canarias (GTC) and the OSIRIS instrument. Using tuneable filters we obser…
The secondary eclipses of WASP-19b as seen by the ASTEP 400 telescope from Antarctica
L. Abe, I. Gonçalves, A. Agabi +29
The ASTEP (Antarctica Search for Transiting ExoPlanets) program was originally aimed at probing the quality of the Dome C, Antarctica for the discovery and characterization of exop…
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…
The SOPHIE search for northern extrasolar planets III. A Jupiter-mass companion around HD 109246
I. Boisse, A. Eggenberger, N. C. Santos +22
We report the detection of a Jupiter-mass planet discovered with the SOPHIE spectrograph mounted on the 1.93-m telescope at the Haute-Provence Observatory. The new planet orbits HD…
