Exoplanet Transit Studies

Extra-solar planetary transits (where the planet is passing across the star in our line of site) involves taking photometry data for several hours during the transit to detect the slight reduction in brightness of the star (increase in magnitude).  This page will present the results of these studies. 

 Amateur exoplanet data is plotted on this web site:
