Abstract

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. The detected sound frequency shift reflects the relative velocity of the 'star' very well. Both teachers and students benefit from the radial velocity method and the transit method (published by us previously) provided by this device. ฉ 2016 IOP Publishing Ltd.
