Physical properties and transmission spectrum of the WASP-74 planetary system from multi-band photometry

L. Mancini, J. Southworth, P. Molliere +32

We present broad-band photometry of eleven planetary transits of the hot Jupiter WASP-74b, using three medium-class telescopes and employing the telescope-defocussing technique. Mo…

OGLE-2014-BLG-1186: gravitational microlensing providing evidence for a planet orbiting the foreground star or for a close binary source?

M. Dominik, E. Bachelet, V. Bozza +40

(abridged) Using the particularly long gravitational microlensing event OGLE-2014-BLG-1186 with a time-scale ~ 300 d, we present a methodology for identifying the na…

VLT/SPHERE robust astrometry of the HR8799 planets at milliarcsecond-level accuracy Orbital architecture analysis with PyAstrOFit

Olivier Wertz, Olivier Absil, Carlos. A. Gómez González +4

HR8799 is orbited by at least four giant planets, making it a prime target for the recently commissioned Spectro-Polarimetric High-contrast Exoplanet REsearch (VLT/SPHERE). As such…
