Detection and Characterization Methods of Exoplanets

, 2020
Is the Solar System unique, or are planets ubiquitous in the universe? The answer to this long-standing question implies the understanding of planet formation, but perhaps more relevant, the observational assessment of the existence of other worlds and their frequency in the galaxy. The detection of planets orbiting other suns has always

The Radial Velocity Method for the Detection of Exoplanets

, 2016
The 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 ...

A Review of Exoplanets Detection Methods

, 2018
A brief introduction to the discovery of planets outside the solar system is presented. Statistical challenges in the analysis of noisy Exoplanets data are indicated, with emphasis on NASA’s Kepler mission.

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.

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

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.

A demonstration device to simulate the radial velocity method for exoplanet detection

Physics Education, 2016
A 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.
