Periodic dimming of light from the star by the transiting planet and the star’s orbital revolution simulate the two major ways of deducing the presence of an exoplanet near a distant star. Apart from being a visual aid for those needing help, the setup also elicited unexpected questions and suggestions from students, who achieved a fairly good level of understanding of the basis for the transit and radial velocity methods.engMahidol UniversityA demonstration setup to simulate detection of planets outside the solar systemArticleIOP Publishing Ltd10.1088/0031-9120/46/5/007
