A novel approach to studying a star's environment from light curves

There are now about 2700 confirmed exoplanets discovered by transiting techniques including those used with the Kepler satellite. The transit method observes the stellar light curve (the flux versus time), and spots the slight dimming of starlight when an exoplanet crosses the face of the star as seen from Earth. The orbital period of the exoplanet can be determined from multiple transits, with the duration and details of the transit dip providing a measure of the planet's size.
