Abstract:
Transit events of extrasolar planets offer a wealth of information for
planetary characterization. However, for many known targets, the
uncertainty of their predicted transit windows prohibits an accurate
scheduling of follow-up observations. In this work, we refine the
ephemerides of 21 hot Jupiter exoplanets with the largest timing
uncertainties. We collected 120 professional and amateur transit light
curves of the targets of interest, observed with a range of telescopes
of 0.3m-2.2m, and analyzed them along with the timing information
of the planets discovery papers. In the case of WASP-117b, we measured
a timing deviation compared to the known ephemeris of about 3.5h, and
for HAT-P-29b and HAT-P-31b the deviation amounted to about 2h and
more. For all targets, the new ephemeris predicts transit timings with
uncertainties of less than 6-min in the year 2018 and less than 13-min
until 2025. Thus, our results allow for an accurate scheduling of
follow-up observations in the next decade.
Description:
We obtained 35 photometric time series of transit events and employed
them together with 85 publically available data sets to refine the
orbital ephemeris of 21 hot Jupiter exoplanets.
We present 35 differential photometry time series of transit events of
different extrasolar planets.
