Context. The detection of reflected light from an exoplanet is a difficult technical challenge at optical wavelengths. Even though this signal is expected to replicate the stellar signal, not only is it several orders of magnitude fainter, but it is also hidden among the stellar noise. Aims. We apply a variant of the cross-correlation technique to HARPS observations of 51 Peg to detect the reflected signal from planet 51 Peg b. Methods. Our method makes use of the cross-correlation function…

Reflected Light from Giant Planets in Habitable Zones: Tapping into the Power of the Cross-Correlation Function

This work attempted to infer the number of hours required for the detection of several planets in their host’s habitable zone using the Cross Correlation Function from theoretical EELT observations and showed that for 5 of the selected planets it should be possible to directly recover their reflected spectral signature.

Detection of planetary signals by reflected light of the host star using the autocorrelation of spectra

We consider an alternative to the cross-correlation function (CCF), that uses the autocor- relation function (ACF), to measure in spectra the reflected light of the stars by their planetary

Doppler shifts and spectral line profile changes in the starlight scattered from an exoplanet

Scattered starlight from an exoplanet, commonly called reflected light, can be used to characterize the planet including the determination of its albedo and inclination of orbit. The relatively low

Using Independent Component Analysis to Detect Exoplanet Reflection Spectrum from Composite Spectra of Exoplanetary Binary Systems

The analysis of the wavelength-dependent albedo of exoplanets represents a direct way to provide insight into their atmospheric composition and to constrain theoretical planetary atmosphere modeling.

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 −4

Discovery of Water at High Spectral Resolution in the Atmosphere of 51 Peg b

We report the detection of water absorption features in the day side spectrum of the first-known hot Jupiter, 51 Peg b, confirming the star–planet system to be a double-lined spectroscopic binary. We

Reflected Light Phase Curves in the TESS Era

The reflected light signal from a planet throughout its orbit is a powerful probe of a planet’s atmospheric properties. There are a number of planets that are amenable to reflected light phase curve


We target the thermal emission spectrum of the non-transiting gas giant HD 88133 b with high-resolution near-infrared spectroscopy, by treating the planet and its host star as a spectroscopic binary.

Multi-Wavelength High-Resolution Spectroscopy for Exoplanet Detection: Motivation, Instrumentation and First Results

Exoplanet research has shown an incessant growth since the first claim of a hot giant planet around a solar-like star in the mid-1990s. Today, the new facilities are working to spot the first

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 from



Spectroscopic direct detection of reflected light from extrasolar planets

At optical wavelengths, an exoplanet's signature is essentially reflected light from the host star - several orders of magnitude fainter. Since it is superimposed on the star spectrum its detection

Aims. We attempt to detect starlight reflected from the hot Jupiter orbiting the main-sequence star τ Boo, in order to determine the albedo of the planetary atmosphere, the orbital inclination of the

Impact of occultations of stellar active regions on transmission spectra: Can occultation of a plage mimic the signature of a blue sky?

Transmission spectroscopy during planetary transits, which is based on the measurements of the variations of planet-to-star radius ratio as a function of wavelength, is a powerful technique to study
