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.

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 ...

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.

ENTROPY OF EXOPLANETS: DETECTION METHODS IN THE CONTEXT OF ACTA UNIVERSI
Detecting the entropy of exoplanets in the context of the Acta Universi hypothesis represents the next great challenge for astronomy. This will require: • New technologies (quantum sensors, interferometry) • New missions (space observatories) • New analysis methods (machine learning, correlation analysis) But the potential reward is huge: the discoveryopenaire +1 more source
Methods for Detecting Cyclotron Maser Radio Emissions from Stars and Exoplanets
The Cyclotron Maser Instability (CMI) is a well-known mechanism responsible for auroral radio emissions from the Earth, Jupiter, Saturn, Uranus, and Neptune. These emissions occur at frequencies near or equal to the local electron cyclotron frequency, which is directly related to the local magnetic field strength.Corentin Louis +6 more
