We report the discovery of WASP-34b, a sub-Jupiter-mass exoplanet transiting its 10.4-magnitude solar-type host star (1SWASP J110135.89-235138.4; TYC 6636-540-1) every 4.3177 days in a slightly eccentric orbit (e = 0.038 ± 0.012). We find a planetary mass of 0.59 ± 0.01 MJup and radius of 1.22 +0.11 −0.08 RJup. There is a linear trend in the radial velocities of 55 ± 4m s −1 y −1 indicating the presence of a long-period third body in the system with a mass >0.45 MJup at a distance of >1.2 AU…

HAT-P-55b: A Hot Jupiter Transiting a Sun-Like Star
We report the discovery of a new transiting extrasolar planet, HAT-P-55b. The planet orbits a V = 13.207 ± 0.039 sun-like star with a mass of 1.013 ± 0.037 M⊙, a radius of 1.011 ± 0.036 R⊙, and a

Discovery of WASP-174b: Doppler tomography of a near-grazing transit
We report the discovery and tomographic detection of WASP-174b, a planet with a near-grazing transit on a 4.23-d orbit around a $V$ = 11.9, F6V star with [Fe/H] = 0.09 $\pm$ 0.09. The planet is in a
THE MASS OF KOI-94d AND A RELATION FOR PLANET RADIUS, MASS, AND INCIDENT FLUX
We measure the mass of a modestly irradiated giant planet, KOI-94d. We wish to determine whether this planet, which is in a 22 day orbit and receives 2700 times as much incident flux as Jupiter, is
FRIENDS OF HOT JUPITERS. II. NO CORRESPONDENCE BETWEEN HOT-JUPITER SPIN–ORBIT MISALIGNMENT AND THE INCIDENCE OF DIRECTLY IMAGED STELLAR COMPANIONS
Multi-star systems are common, yet little is known about a stellar companion's influence on the formation and evolution of planetary systems. For instance, stellar companions may have facilitated the
Spitzer Dayside Emission of WASP-34b
We analyzed two eclipse observations of the low-density transiting, likely grazing, exoplanet WASP-34b with the Spitzer Space Telescope’s InfraRed Array Camera using two techniques to correct for
TESS Transit Timing of Hundreds of Hot Jupiters
We provide a database of transit times and updated ephemerides for 382 planets based on data from the NASA Transiting Exoplanet Survey Satellite (TESS) and previously reported transit times, which
Mass-loss rates for transiting exoplanets
Exoplanets at small orbital distances from their host stars are submitted to intense levels of energetic radiations, X-rays, and extreme ultraviolet (EUV). Depending on the masses and densities of
On a Possible Solution to the Tidal Realignment Problem for Hot Jupiters
TLDR
The model implies that hot Jupiters orbiting cool stars are probably not in immediate danger of being devoured by their host stars while they are on the main sequence, and a testable prediction of the model is that hot Jupiter hosts with orbital periods shorter than 2–3 days should have obliquities much smaller than 1°.

HAT-P-14b: A 2.2?M J Exoplanet Transiting a Bright F Star
We report the discovery of HAT-P-14b, a fairly massive transiting extrasolar planet orbiting the moderately bright star GSC 3086-00152 (V = 9.98), with a period of P = 4.627669 ± 0.000005 days. The
WASP-25b: A 0.6M planet in the Southern hemisphere
TLDR
The relationship of planetary radius to planetary equilibrium temperature and host star metallicity for transiting exoplanets with a similar mass to WASP-25b is investigated, finding that these two parameters explain the radii of most low-mass planets well.

WASP-17b: AN ULTRA-LOW DENSITY PLANET IN A PROBABLE RETROGRADE ORBIT
TLDR
It will be important to determine more precisely the current orbital eccentricity by further high-precision radial velocity measurements or by timing the secondary eclipse, both to reduce the uncertainty on the planet's radius and to test tidal-heating models.
WASP-3b: a strongly irradiated transiting gas-giant planet
TLDR
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.
TrES-2: The First Transiting Planet in the Kepler Field
