dc.description.abstractWe update the main physical and orbital properties of the transiting hot Saturn planet HAT-P-19 b, based on a global modelling of high-precision transit and occultation light curves, taken with ground-based and space telescopes, archive spectra and radial velocity measurements, brightness values from broad-band photometry, and Gaia parallax. We collected 65 light curves by amateur and professional observers, measured mid-transit times, and analysed their differences from calculated transit timings based on reference ephemeris information, which we update as a result. We have not found any periodicity in the residuals of a linear trend, which we attribute to the accumulation of uncertainties in the reference mid-transit time and the orbital period. We comment on the scenarios describing the formation and migration of this hot-Saturn type exoplanet with a bloated atmosphere yet a small core, although it is orbiting a metal-rich ([Fe/H] = 0.24 dex) host star. Finally, we review the planetary mass-radius, the orbital period-radius, and density, and the stellar metallicity-core mass diagrams, based on the parameters we derive for HAT-P-19 b and those of the other 70 transiting Saturn-mass planets from the NASA Exoplanet Archive.

dc.description.sponsorshipWe gratefully acknowledge the support by The Scientific and Technological Research Council of Turkey (TUBITAK) with the project 116F350. We thank TUBITAK for the partial support in using T100 telescope with the project numbers 12CT100-378 and 16CT1001096. TD acknowledges support from MIT's Kavli Institute as a Kavli postdoctoral fellow. This research has made use of the SVO Filter Profile Service (http://svo2.cab.inta-csic.es/theory/fps/) supported by the Spanish MINECO through grant AYA2017-84089. Some of the data presented herein were obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California, and the National Aeronautics and Space Administration. The Observatory was made possible by the generous financial support of the W.M. Keck Foundation. We thank all the amateur and professional observers who report their data to Exoplanet Transit Database (ETD), permitted us to use them, and answered all of our never-ending questions. We acknowledge the work put on the computer code gpc by Nestor Espinoza. We thank Heather Knutson for kindly sharing the Spitzer light curves of the target with us. We also thank Jason Eastman for his guidance and help by answering our questions in using the EXOFAST software package. This publication makes use of data products from theWide-field Infrared Survey Explorer, which is a joint project of the University of California, Los Angeles, and the Jet Propulsion Laboratory/California Institute of Technology, funded by the National Aeronautics and Space Administration.
