We present high-precision K-band photometry of the transit and secondary eclipse of extra-solar planet OGLE-TR-113, using the SOFI near-infrared instrument on European Southern Observatory's New Technology Telescope. Data were taken in 5-s exposures over two periods of 3-A h, using random jitter position offsets. In this way, a relative photometric precision of ∼1 per cent per frame was achieved, avoiding systematic effects that seem to become dominant at precisions exceeding this level, and…

3.8-μm photometry during the secondary eclipse of the extrasolar planet HD 209458b
We report infrared photometry of the extrasolar planet HD 209458b during the time of secondary eclipse (planet passing behind the star). Observations were acquired during two secondary eclipses at
Ground-based detection of thermal emission from the exoplanet WASP-19b ?
An occultation of the newly discovered hot Jupiter system WASP-19 is observed with the High Acuity Wide-field K-band Imager instrument on the VLT in order to measure thermal emission from the planet's dayside at ∼2μm, indicating that the planet shows poor redistribution of heat to the night side, consistent with models of highly irradiated planets.

A Ground‐based Search for Thermal Emission from the Exoplanet TrES‐1
Eclipsing planetary systems give us an important window on extrasolar planet atmospheres. By measuring the depth of the secondary eclipse, when the planet moves behind the star, we can estimate the

We present six new transits of the hot Jupiter OGLE-TR-113b observed with MagIC on the Magellan Telescopes between 2007 January and 2009 May. We update the system parameters and revise the planetary
VLT transit and occultation photometry for the bloated planet CoRoT-1b
We present VLT eclipse photometry for the giant planet CoRoT-1b. We observed a transit in the R-band filter and an occultation in a narrow filter centered on 2.09 μm. Our analysis of this new

We present H- and Ks-band photometry bracketing the secondary eclipse of the hot Jupiter TrES-3b using the Wide-field Infrared Camera on the Canada-France-Hawaii Telescope. We detect the secondary
Hot nights on extrasolar planets: mid‐infrared phase variations of hot Jupiters
We present results from Spitzer Space Telescope observations of the mid-infrared phase variations of three short-period extrasolar planetary systems: HD 209458, HD 179949 and 51 Peg. We gathered
Thermal Emission from Transiting Very Hot Jupiters: Prospects for Ground-based Detection at Optical Wavelengths
Very hot Jupiters (VHJs) are defined as Jupiter-mass extrasolar planets with orbital periods shorter than 3 days. For low albedos the effective temperatures of irradiated VHJs can reach 2500-3000 K.

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.
