Transiting Exoplanet Monitoring Project (TEMP). I. Refined System Parameters and Transit Timing Variations of HAT-P-29b

Abstract

We report the photometry of six transits of the hot Jupiter HAT-P-29b obtained from 2013 October to 2015 January. We analyze the new light curves, in combination with the published photometric, and Doppler velocimetric, and spectroscopic measurements, finding an updated orbital ephemeris for the HAT-P-29 system, $T_{\mathrm{C}}[0]=2456170.5494(15)[\mathrm{BJ}{\mathrm{D}}_{\mathrm{TDB}}]$ and $P=5.723390(13)\mathrm{days}$. It is $17.63\mathrm{s}$ ($4.0\sigma$) longer than the previously published value, amounting to errors exceeding $2.5\mathrm{hrs}$ at the time of writing (on UTC 2018 June 1). The measured transit mid-times for HAT-P-29b show no compelling evidence of timing anomalies from a linear model, which rules out the presence of a perturbers with masses greater than $0.6$, $0.7$, $0.5$, and $0.4{\mathrm{M}}_{\oplus }$ near the $1:2$, $2:3$, $3:2$, and $2:1$ resonances with HAT-P-29b, respectively.
