The star XO-5 (GSC 02959?00729, -->V = 12.1, G8 V) hosts a Jupiter-sized, -->Rp = 1.15 ? 0.12 RJ, transiting extrasolar planet, XO-5b, with an orbital period of 4.2 days. The planet's mass, -->Mp = 1.15 ? 0.08 MJ, and surface gravity, -->gp = 22 ? 5 m s?2, are large for its orbital period compared to most other transiting planets. However, the deviation from the -->Mp-P relationship for XO-5b is not as large as for GJ 436b, HAT-P-2b, and XO-3b. By coincidence, XO-5 overlies the extreme H I… 
Discovery of XO-6b: a hot Jupiter transiting a fast rotating F5 star on an oblique orbit
Only a few hot Jupiters are known to orbit around fast rotating stars. These exoplanets are harder to detect and characterize and may be less common than around slow rotators. Here, we report the
HAT-P-34b-HAT-P-37b: Four Transiting Planets More Massive than Jupiter Orbiting Moderately Bright Stars
We report the discovery of four transiting extrasolar planets (HAT-P-34b–HAT-P-37b) with masses ranging from 1.05 to 3.33 M_J and periods from 1.33 to 5.45 days. These planets orbit relatively
Photometric follow-up observations of the transiting neptune-mass planet GJ 436b
This paper presents multiband photometric follow-up observations of the Neptune-mass transiting planet GJ?436b, consisting of five new ground-based transit light curves obtained in 2007 May. Together
XO-7 b: A Transiting Hot Jupiter with a Massive Companion on a Wide Orbit
Transiting planets orbiting bright stars are the most favorable targets for follow-up and characterization. We report the discovery of the transiting hot Jupiter XO-7 b and of a second, massive
The Curious Case of KOI 4: ConfirmingKepler’sFirst Exoplanet Detection
The discovery of thousands of planetary systems by Kepler has demonstrated that planets are ubiquitous. However, a major challenge has been the confirmation of Kepler planet candidates, many of which
A SUPER-EARTH-SIZED PLANET ORBITING IN OR NEAR THE HABITABLE ZONE AROUND A SUN-LIKE STAR
We present the discovery of a super-Earth-sized planet in or near the habitable zone of a Sun-like star. The host is Kepler-69, a 13.7 mag G4V-type star. We detect two periodic sets of transit
Independent Confirmation and Refined Parameters of the Hot Jupiter XO-5b
We present HATNet observations of XO-5b, confirming its planetary nature based on evidence beyond that described in the announcement of Burke et al., namely, the lack of significant correlation
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. I. A RADIAL VELOCITY SEARCH FOR MASSIVE, LONG-PERIOD COMPANIONS TO CLOSE-IN GAS GIANT PLANETS
In this paper we search for distant massive companions to known transiting hot Jupiters that may have influenced the dynamical evolution of these systems. We present new radial velocity observations
Independent discovery of the transiting exoplanet HAT-P-14b
TLDR
The authors' analysis of HAT-P-14/WASP-27 is in good agreement with the values found by Torres et al. and suggests that the planet may undergo a grazing secondary eclipse and tightly constrain the system parameters.
