| Summary: | We constructed a simple demonstration setup to simulate an extrasolar planet
and its star revolving around the system’s centre of mass. 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. |
