We present the detection of visible light from the planet TrES-2b, the darkest exoplanet currently known. By analysis of the orbital photometry from publicly available Kepler data (0.4–0.9 μm), we determine a day–night contrast amplitude of 6.5 ± 1.9 ppm (parts per million), constituting the lowest amplitude orbital phase variation discovered. The signal is detected to 3.7σ confidence and persists in six different methods of modelling the data and thus appears robust. In contrast, we are unable… Expand

Direct Detection of extra-solar Planets with ESPRESSO
In visible wavelengths, an exoplanet’s signature is essentially reflected light from the host star several orders of magnitude fainter. Unfortunately, it is superimposed on the star spectrum andExpand
The Very Low Albedo of WASP-12b from Spectral Eclipse Observations with Hubble
We present an optical eclipse observation of the hot Jupiter WASP-12b using the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope. These spectra allow us to place an upperExpand
OPTICAL PHASE CURVES OF KEPLER EXOPLANETS
We conducted a comprehensive search for optical phase variations of all close-in (a/R{sub *} 1), so we conclude that they are likely to be self-luminous objects rather than planets. The other sixExpand
Polarization of hot Jupiter systems: a likely detection of stellar activity and a possible detection of planetary polarization
We present high-precision linear polarization observations of four bright hot Jupiter systems (τ Boo, HD 179949, HD 189733, and 51 Peg) and use the data to search for polarized reflected light fromExpand
SEVEN NEW BINARIES DISCOVERED IN THE KEPLER LIGHT CURVES THROUGH THE BEER METHOD CONFIRMED BY RADIAL-VELOCITY OBSERVATIONS
We present seven newly discovered non-eclipsing short-period binary systems with low-mass companions, identified by the recently introduced BEER algorithm, applied to the publicly available 138-dayExpand
Searching for reflected light from τ Bootis b with high-resolution ground-based spectroscopy : Approaching the 10-5 contrast barrier
Context. It is challenging to measure the starlight reflected from exoplanets because of the extreme contrast with their host stars. For hot Jupiters, this contrast is in the range of 10 −6 to 10 −4Expand
The stellar obliquity, planet mass, and very low albedo of Qatar-2 from K2 Photometry
The Qatar-2 transiting exoplanet system was recently observed by the {\it Kepler} telescope as part of {\it K2} Campaign 6. The photometric time series has one-minute time sampling and a precision ofExpand
Changing Phases of Alien Worlds: Probing Atmospheres of Kepler Planets with High-Precision Photometry
We present a comprehensive analysis of planetary phase variations, including possible planetary light offsets, using eighteen quarters of data from the Kepler space telescope. After correcting forExpand
Transit timing of TrES-2: a combined analysis of ground- and space-based photometry
Homogeneous observations and careful analysis of transit light curves can lead to the identification of transit timing variations (TTVs). TrES-2 is one of few exoplanets, which offer the matchlessExpand
Features in the broad-band eclipse spectra of exoplanets: signal or noise?
A planet's emission spectrum contains information about atmospheric composition and structure. We compare the Bayesian Information Criterion (BIC) of blackbody fits and idealized spectral retrievalExpand
