We present new spectroscopic and photometric observations of the transiting exoplanetary system WASP-3. Spectra obtained during two separate transits exhibit the Rossiter–McLaughlin (RM) effect and allow us to estimate the sky-projected angle between the planetary orbital axis and the stellar rotation axis, λ = 3.3+2.5−4.4 deg. This alignment between the axes suggests that WASP-3b has a low orbital inclination relative to the equatorial plane of its parent star. During our first night of…

Context. Hot-Jupiter planets must form at large separations from their host stars where the temperatures are cool enough for their cores to condense. They then migrate inwards to their current

Prospecting transit duration variations in extrasolar planetary systems

Context. Transiting planetary systems allow us to extract geometrical information, e.g., the anglebetween the orbital angular momentum and the stellar spin, that can be used to discriminate among

CONSTRAINTS ON A SECOND PLANET IN THE WASP-3 SYSTEM

There have been previous hints that the transiting planet WASP-3b is accompanied by a second planet in a nearby orbit, based on small deviations from strict periodicity of the observed transits. Here

Spin-orbit angle measurements for six southern transiting planets: New insights into the dynamical origins of hot Jupiters

The goal is to measure the degree of alignment between planetary orbits and stellar spin axes, to search for potential correlations with eccentricity or other planetary parameters and to measure long term radial velocity variability indicating the presence of other bodies in the system.

The thermal emission of the exoplanet WASP-3b

We report the detection of thermal emission from the transiting hot Jupiter WASP-3b at 3.6, 4.5 and 8.0 μ mu sing theSpitzer Space Telescope. We obtain planet-to-star flux ratios of 0.209 +0.040

We use the distribution of extrasolar planets in circular orbits around stars with surface convective zones detected by ground-based transit searches to constrain how efficiently tides raised by the

TIDAL DISSIPATION AND OBLIQUITY EVOLUTION IN HOT JUPITER SYSTEMS

Two formation scenarios have been proposed to explain the tight orbits of hot Jupiters. They could be formed in orbits with a small inclination (with respect to the stellar spin) via disk migration,
