Abstract:
We present 10 new transit light curves of the transiting hot Jupiter
HAT-P-13b, obtained during two observational seasons by three
different telescopes. When combined with 12 previously published light
curves, we have a sample consisting of 22 transit light curves,
spanning 1041 days across four observational seasons. We use this
sample to examine the recently observed large-amplitude transit timing
variations (TTVs) by Pal et al. (2011MNRAS.413L..43P 2011MNRAS.413L..43P) and give refined
system parameters. We find that the transit times are consistent with
a linear ephemeris, with the exception of a single transit time, from
UT 2009 November 5, for which the measured mid-transit time
significantly deviates from our linear ephemeris. The nature of this
deviation is not clear, and the rest of the data do not show any
significant TTVs.
Description:
Our 10 new transit light curves of HAT-P-13b from Seasons 3 and 4 were
obtained at three observatories. Fred Lawrence Whipple Observatory,
located on Mount Hopkins, near Amado, AZ. Faulkes Telescope North,
located on Mauna Haleakala in Maui, HI. Byrne Observatory at Sedgwick,
located at the Sedgwick Reserve near Santa Ynez, CA.
