On the long-term correlation between the flux in the Ca II H & K and Halpha lines for FGK stars
J. Gomes da Silva, N. C. Santos, I. Boisse +2
The re-emission in the cores of the Ca II H & K and H lines, are well known proxies of stellar activity. However, these activity indices probe different activity phenomena, the…
The SOPHIE search for northern extrasolar planets: VI. Three new hot Jupiters in multi-planet extrasolar systems
C. Moutou, G. Hebrard, F. Bouchy +21
We present high-precision radial-velocity measurements of three solar-type stars: HD 13908, HD 159243, and HIP 91258. The observations were made with the SOPHIE spectrograph at the…
World-leading science with SPIRou - the nIR spectropolarimeter / high-precision velocimeter for CFHT
X. Delfosse, J. -F. Donati, D. Kouach +22
SPIRou is a near-infrared (nIR) spectropolarimeter / velocimeter proposed as a new-generation instrument for CFHT. SPIRou aims in particular at becoming world-leader on two forefro…
Effect of stellar spots on high-precision transit light-curve
M. Oshagh, N. C. Santos, I. Boisse +4
Stellar activity features such as spots can create complications in determining planetary parameters through spectroscopic and photometric observations. The overlap of a transiting…
Analysis of spin-orbit alignment in the WASP-32, WASP-38, and HAT-P-27/WASP-40 systems
D. J. A. Brown, A. Collier Cameron, R. F. Díaz +14
We present measurements of the spin-orbit alignment angle, lambda, for the hot Jupiter systems WASP-32, WASP-38, and HAT-P-27/WASP-40, based on data obtained using the HARPS spectr…
