Abstract:
A promising method for detecting earth-sized exoplanets is the timing
analysis of a known transit. The technique allows a search for
variations in either the transit duration or the center induced by the
perturbation of a third body, e.g. a second planet or an exomoon. By
applying this method, the TASTE (The Asiago Search for Transit Timing
variations of Exoplanets) project will collect high- precision,
short-cadence light curves for a selected sample of transits by using
imaging differential photometry at the Asiago 1.82m telescope. The
first light curves show that our project can achieve a competitive
timing accuracy, as well as a significant improvement of the orbital
parameters. We derived refined ephemerides for HAT-P-3b and HAT-P-14b
with a timing accuracy of 11 and 25s, respectively.
