Abstract:
A possible transit of HAT-P-13c has been predicted to occur on 2010
April 28. Here we report on the results of a multi-site campaign that
has been organised to detect the event. CCD photometric observations
have been carried out at five observatories in five countries. We
reached 30% time coverage in a 5 days interval centered on the
suspected transit of HAT-P-13c. Two transits of HAT-P-13b were also
observed. No transit of HAT-P-13c has been detected while the campaign
was on. By a numerical experiment with 105 model systems we conclude
that HAT-P-13c is not a transiting exoplanet with a significance level
from 65% to 72%, depending on the planet parameters and the prior
assumptions. We present two times of transit of HAT-P-13b ocurring at
BJD 2455141.5522±0.0010 and BJD 2455249.4508±0.0020. The TTV of
HAT-P-13b is consistent with zero within 0.001 days. The refined
orbital period of HAT-P-13b is 2.916293±0.000010 days.
Description:
Transit light curves of HAT-P-13b at JD2455141 and JD 2455249 are
presented. Johnson R and V filters were used. Time is barycentric
corrected. A decorrelation for external parameters (background,
seeing, flat residuals) has been applied to photometry.
