Determinação da massa e dados orbitais de exoplanetas pelo método Doppler

Abstract

Doppler method, also called radial velocities method, is a technique used in detecting of exoplanets. About 70% of known exoplanets were discovered using this technique. The Doppler method consist in determine spectral shifts of host star of exoplanet, which enable measurement of the variation of radial velocity of host star towards of Earth or away from Earth. This movement of host star around center of mass occurs due to the existence of exoplanet. In this work we present a pedagogical review of the Doppler method applied to detection of exoplanets. In this sense, we analyze theoretical elements of this technique and their application.
