Hot Jupiters are a class of extrasolar planet that orbit their parent stars at very short distances. They are expected to be tidally locked, which can lead to a large temperature difference between their daysides and nightsides. Infrared observations of eclipsing systems have yielded dayside temperatures for a number of transiting planets. The day–night contrast of the transiting extrasolar planet HD 189733b was ‘mapped’ using infrared observations. It is expected that the contrast between the… 

Climate of an ultra hot Jupiter

We present the analysis of a full-orbit, spectroscopic phase curve of the ultra hot Jupiter (UHJ) WASP-18b, obtained with the Wide Field Camera 3 aboard the Hubble Space Telescope. We measured the

Bright optical day-side emission from extrasolar planet CoRoT-2b

We present our analysis of the red-channel CoRoT data of extrasolar planet CoRoT-2b. A deep secondary eclipse is detected at a level of 1.02 ±0.20 ×10 −4 , which suggests that all of the


We present a semi-analytic model atmosphere for close-in exoplanets that captures the essential physics of phase curves: orbital and viewing geometry, advection, and re-radiation. We calibrate the

Kepler’s Optical Phase Curve of the Exoplanet HAT-P-7b

The Kepler mission is performing at the level required to detect Earth-size planets orbiting solar-type stars, including data for the previously known giant transiting exoplanet HAT-P-7b, which shows a smooth rise and fall of light from the planet as it orbits its star, punctuated by a drop when the planet passes behind its star.

Abstract The last few years has seen a dramatic increase in the number of exoplanets known and in the range of methods for characterising their atmospheric properties. At the same time, new

TESS Full Orbital Phase Curve of the WASP-18b System

We present a visible-light full orbital phase curve of the transiting planet WASP-18b measured by the TESS mission. The phase curve includes the transit, secondary eclipse, and sinusoidal modulations

The return of the mummy: Evidence for starlight reflected from the massive hot Jupiter τ Boo b?

Very recently, we were able to measure CO absorption features in the atmosphere of the non-transiting planet τ Boo b for the very first time. This allowed us to unravel a long-term mystery in planet

The secondary eclipse of CoRoT-1b

The transiting planet CoRoT-1b is thought to belong to the pM-class of planets, in which the thermal emission dominates in the optical wavelengths. We present a detection of its secondary eclipse in

TESS Phase Curve of the Hot Jupiter WASP-19b

We analyze the phase curve of the short-period transiting hot Jupiter system WASP-19, which was observed by the Transiting Exoplanet Survey Satellite (TESS) in Sector 9. WASP-19 is one of only five


This paper reports the discovery and characterization of the transiting hot giant exoplanet Kepler-17b. The planet has an orbital period of 1.486 days, and radial velocity measurements from the



A map of the day–night contrast of the extrasolar planet HD 189733b

Observations of HD 189733, the closest of these eclipsing planetary systems, over half an orbital period are reported, from which a ‘map’ of the distribution of temperatures is constructed, indicating that energy from the irradiated dayside is efficiently redistributed throughout the atmosphere.

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

Infrared radiation from an extrasolar planet

A class of extrasolar giant planets—the so-called ‘hot Jupiters’ (ref. 1)—orbit within 0.05 au of their primary stars (1 au is the Sun–Earth distance). These planets should be hot and so emit

Detection of Thermal Emission from an Extrasolar Planet

We present Spitzer Space Telescope infrared photometric time series of the transiting extrasolar planet system TrES-1. The data span a predicted time of secondary eclipse, corresponding to the

Scattered Light from Close-in Extrasolar Planets: Prospects of Detection with the MOST Satellite

The ultraprecise photometric space satellite MOST (Microvariability and Oscillations of STars) will provide the first opportunity to measure the albedos and scattered light curves from known


We present new Spitzer observations of the phase variation of the hot Jupiter HD 189733b in the MIPS 24 μm bandpass, spanning the same part of the planet's orbit as our previous observations in the

The hottest planet

Direct detection of thermal emission from the smallest known transiting planet, HD 149026b, that indicates a brightness temperature of 2,300 ± 200 K at 8 µm is reported, which may give rise to novel atmospheric properties yet to be investigated.

The Very Low Albedo of an Extrasolar Planet: MOST Space-based Photometry of HD 209458

Measuring the albedo of an extrasolar planet provides insight into its atmospheric composition and its global thermal properties, including heat dissipation and weather patterns. Such a measurement

Theoretical Spectra and Light Curves of Close-in Extrasolar Giant Planets and Comparison with Data

We present theoretical atmosphere, spectral, and light-curve models for extrasolar giant planets (EGPs) undergoing strong irradiation for which Spitzer planet/star contrast ratios or light curves

The close-in extrasolar giant planets (CEGPs), ≲0.05 AU from their parent stars, may have a large component of optically reflected light. We present theoretical optical photometric light curves and
