Optimal method for exoplanet detection by angular differential imaging
Journal of the Optical Society of America A, 2009We propose a novel method for the efficient direct detection of exoplanets from the ground using angular differential imaging. The method combines images appropriately, then uses the combined images jointly in a maximum-likelihood framework to estimate the position and intensity of potential planets orbiting the observed star. It takes into account the

New Methods for the Detection and Characterization of Exoplanets
2022Advancements in detection technologies have allowed the discovery of thousands of exoplanets. These discoveries have revolutionized our understanding of the Universe; not only are planets ubiquitous, but the planetary systems they populate are as diverse as the complex processes that govern their formation allow. This thesis compiles several studies on

Comparison of methods for detection and characterization of exoplanets with SPHERE/IRDIS
SPIE Proceedings, 2010SPHERE is a second generation instrument for the Very Large Telescope (VLT) which will aim at directly detecting the intrinsic flux of young giant exoplanets thanks to a dedicated extreme adaptive optics system and coronagraphs. Exoplanet detection in the near-infrared will be performed in parallel with an integral field spectrograph and a ...

Oukaimeden Observatory: detection of exoplanet HD 189733b by the transit method
SPIE Proceedings, 2010In this paper we report the detection and characterization of HD 189733b, the peculiarity of this exoplanet is that the flow of the target star is decreased significantly (~ 3%) during the transit. We determined the radius of the exoplanet 1.27 ± 0.03 RJ, the impact parameter 0.70 ± 0.02, and the inclination of the orbit 85.4 ± 0.1°. The transit of

The Radial Velocity Method for the Detection of Exoplanets
2016The radial velocity (RV) method has provided the foundation for the research field of exoplanets. It created the field by discovering the first exoplanets and then blazed a trail by detecting over 1000 exoplanets in orbit around other stars. The method also plays a vital role in transit searches by providing the planetary mass needed to calculate the ...

Image processing methods for exoplanets detection and characterization in starshade observations
Space Telescopes and Instrumentation 2018: Optical, Infrared, and Millimeter Wave, 2018A starshade is a promising instrument for the direct imaging and characterization of exoplanets. However, even with a starshade, exoplanets are difficult to detect because detector noise, starshade defects, and misalignment (dynamics of the starshade system) degrade the signal to noise ratio (SNR) and contrast.

A demonstration device to simulate the radial velocity method for exoplanet detection
Physics Education, 2016A device for simulating exoplanet detection by the radial method based on the Doppler principle has been constructed. The spectral shift of light from a distant star, mutually revolving with the exoplanet, is simulated by the spectral shift of the sound wave emitted by the device's star approaching and receding relative to the static frequency detector.

Detection Methods and Properties of Known Exoplanets
2008Following the historic discovery of the first extrasolar planet, 51 Pegasi b, in 1995 (Mayor and Queloz, 1995) more than 200 planets orbiting other stars have now been catalogued. The vast majority of these planets have been detected with the radial velocity technique, which is biased towards heavy, close-orbiting planets.
