In this work, we investigate the problem concerning the presence of additional bodies gravitationally bound with the WASP-3 system. We present eight new transits of this planet gathered between 2009 May and 2011 September by using the 30-cm telescope at the Crow Observatory-Portalegre, and analyse all the photometric and radial velocity data published so far. We did not observe significant periodicities in the Fourier spectrum of the observed minus calculated (O − C) transit timing and radial… Expand
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. HereExpand
Transiting Exoplanet Monitoring Project (TEMP). VI. The Homogeneous Refinement of System Parameters for 39 Transiting Hot Jupiters with 127 New Light Curves
We present 127 new transit light curves for 39 hot Jupiter systems, obtained over the span of 5 yr by two ground-based telescopes. A homogeneous analysis of these newly collected light curvesExpand
Transit Timing Variation Measurements of WASP-12b and Qatar-1b: No Evidence for Additional Planets
WASP-12b and Qatar-1b are transiting Hot Jupiters for which previous works have suggested the presence of transit timing variations (TTVs) indicative of additional bodies in these systems - anExpand
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 +0.040Expand
Visible-light Phase Curves from the Second Year of the TESS Primary Mission
We carried out a systematic study of full-orbit phase curves for known transiting systems in the northern ecliptic sky that were observed during Year 2 of the TESS primary mission. We applied theExpand
Homogeneously derived transit timings for 17 exoplanets and reassessed TTV trends for WASP-12 and WASP-4
We homogeneously analyse ∼3.2 × 105 photometric measurements for ∼1100 transit light curves belonging to 17 exoplanet hosts. The photometric data cover 16 years (2004–2019) and include amateur andExpand
On the Detection of Extrasolar Moons and Rings
Since the discovery of a planet transiting its host star in the year 2000, thousands of additional exoplanets and exoplanet candidates have been detected, mostly by NASA's Kepler space telescope.Expand
Further constraints on the optical transmission spectrum of HAT-P-1b
We report on novel observations of HAT-P-1 aimed at constraining the optical transmission spectrum of the atmosphere of its transiting Hot-Jupiter exoplanet. Ground-based differentialExpand
Warm Spitzer occultation photometry of WASP-26b at 3.6 and 4.5 μm
We present new warm Spitzer occultation photometry of WASP-26 at 3.6 and 4.5µm along with new transit photometry taken in the g, r and i bands. We report the first detection of the occultation ofExpand
Formation, habitability, and detection of extrasolar moons.
It is shown that natural satellites in the range of 0.1-0.5 Earth mass are potentially habitable, can form within the circumplanetary debris and gas disk or via capture from a binary, and are detectable with current technology. Expand


We present time series photometry and constraints on additional planets in five of the exoplanetary systems studied by the EPOCh (Extrasolar Planet Observation and Characterization) component of theExpand
Possibility of a photometric detection of exomoons
Aims. We examined which exo-systems contain moons that may be detected in transit. Methods. We numerically modeled transit light curves of Earth-like and giant planets that cointain moons withExpand
WASP-3b: a strongly irradiated transiting gas-giant planet
The proximity and relative temperature of the host star suggests that WASP-3b is one of the hottest exoplanets known, and thus has the potential to place stringent constraints on exoplanet atmospheric models. Expand
A Prograde, Low-inclination Orbit for the Very Hot Jupiter WASP-3b
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 andExpand
The Doppler shadow of WASP-3b A tomographic analysis of Rossiter-McLaughlin observations
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 currentExpand
Starspots and Spin-orbit Alignment in the WASP-4 Exoplanetary System
We present photometry of 4 transits of the exoplanet WASP-4b, each with a precision of approximately 500 ppm and a time sampling of 40-60 s. We have used the data to refin e the estimates of theExpand
Transit timing effects due to an exomoon
In our previous paper, we evaluated the transit duration variation (TDV) effect for a co-aligned planet-moon system at an orbital inclination of i=90 degrees. Here, we will consider the effect forExpand
Detection of Planetary Transits Across a Sun-like Star.
High-precision, high-cadence photometric measurements of the star HD 209458 are reported, which is known from radial velocity measurements to have a planetary-mass companion in a close orbit and the detailed shape of the transit curve due to both the limb darkening of thestar and the finite size of the planet is clearly evident.

We present an analysis of 11 yr of precision radial velocity measurements of 76 nearby solar-type stars from the Lick radial velocity survey. For each star, we report on variability, periodicity, andExpand
The spin–orbit alignment of the transiting exoplanet WASP-3b from Rossiter–McLaughlin observations
We present an observation of the Rossiter-McLaughlin effect for the planetary system WASP-3. Radial velocity measurements were made during transit using the SOPHIE spectrograph at the 1.93-mExpand
