We report the discovery of TrES-4, a hot Jupiter that transits the star GSC 02620-00648 every 3.55 days. From high-resolution spectroscopy of the star, we estimate a stellar effective temperature of K, and T p 6100 150 eff from high-precision z and B photometry of the transit we constrain the ratio of the semimajor axis a and the stellar radius to be . We compare these values to model stellar isochrones to constrain the stellar Ra /R p 6.03 0.13 ∗∗ mass to be . Based on this estimate and the… Expand

Wasp-22 b: A transiting "hot jupiter" planet in a hierarchical triple system
TLDR
High-resolution spectroscopy obtained with the CORALIE and HARPS spectrographs confirms the presence of a planetary mass companion with an orbital period of 3.533 days in a near-circular orbit in the star TYC 6446-326-1. Expand
WASP-39b: a highly inflated Saturn-mass planet orbiting a late G-type star
TLDR
The discovery of WASP-39b is presented, a highly inflated transiting Saturn-mass planet orbiting a late G-type dwarf star, and the metallicity and temperatures are found to have an equilibrium temperature of 1116 +33 −32 K. Expand
High‐precision transit observations of the exoplanet WASP‐13b with the RISE instrument
WASP-13b is a sub-Jupiter mass exoplanet orbiting a G1V type star with a period of 4.35 d. The current uncertainty in its impact parameter (0 < b < 0.46) results in poorly defined stellar andExpand
