Detection Methods and Properties of Known Exoplanets

, 2008
Following 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.

Oukaimeden Observatory: detection of exoplanet HD 189733b by the transit method

SPIE Proceedings, 2010
In 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

Image processing methods for exoplanets detection and characterization in starshade observations

Space Telescopes and Instrumentation 2018: Optical, Infrared, and Millimeter Wave, 2018
A 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.
