Abstract

(Abstract only) For exoplanets that transit between their host star and Earth, periodic variations in mid-transit time can indicate another planet’s gravitational influence. We investigate 31 transits of TrES-1 b observed from 6-inch telescopes in the MicroObservatory network. The EXOplanet Transit Interpretation Code (EXOTIC) is used to fit light curves and find transit midpoints. Our analysis did not indicate the existence of other planets affecting the orbit of TrES-1 b.
