Abstract:
TASTE (The Asiago Search for Transit timing variations of Exoplanets)
project is collecting high-precision, short-cadence light curves for a
selected sample of transiting exoplanets. It has been claimed that the
hot jupiter HAT-P-13b suddenly deviated from a linear ephemeris by
∼20min, implying that there is a perturber in the system. Using five
new transits, we discuss the plausibility of this transit time
variation (TTV), and show that a periodic signal should not be
excluded. More follow-up observations are required to constrain the
mass and the orbit of the hypothetical perturber.
