Exoplanet Detection by Astrometric Method

Xu, W. W.; Liao, X. H.; Zhou, Y. H. +1 more

As we known, the exoplanets are mostly detected by the methods of radial velocity and transit, only one is found by the astrometric method. As the data of the gaia to be released, astrometry will become one of the most important method for detecting exoplanets gradually. Based on the position sequence of stars, this paper discusses the calculation…

Analogue Simulation and Orbital Solving Algorithm of Astrometric Exoplanet Detection

Ji, J. H.; Huang, P. H.

Astrometry is an effective method to detect exoplanets. It has many advantages that other detection methods do not bear, such as providing three dimensional planetary orbit and determining the planetary mass. Astrometry will enrich the sample of exoplanets. As the high-precision astrometric satellite Gaia (Global Astrometry interferometer for Astr…
