Abstract:
The loneliness of hot Jupiters supports the high-eccentricity
migration as a primary path leading to the formation of systems with
those planets stripped of any close-in planetary companions. Here we
present the null results of searches for low-mass planets close to hot
Jupiters in 10 planetary systems: HAT-P-4, HAT-P-10, HAT-P-12,
HAT-P-17, HAT-P-19, HAT-P-32, HAT-P-44, Qatar-6, TrES-4, and WASP-48.
We employed multi-sector time-series photometry from the Transiting
Exoplanet Survey Satellite enhanced with new ground-based transit
light curves to determine the sizes of hypothetical planets that might
still avoid being detected. We redetermined transit parameters for the
known hot Jupiters using a homogeneous approach. We refuted transit
timing variations for HAT-P-12 b, claimed recently in the literature.
The transit timing data permitted us to place tighter constraints on
third bodies in HAT-P-19 and HAT-P-32 systems detected in Doppler
measurements. We also study four multi-periodic pulsating variable
stars in the field around HAT-P-17.
Description:
We provide the photometric time series for transits of HAT-P-4 b,
HAT-P-10 b, HAT-P-12 b, HAT-P-17 b, HAT-P-19 b, HAT-P-32 b, HAT-P-44
b, Qatar-6 b, TrES-4 b, and WASP-48 b acquired with the instruments:
the 2.0m Liverpool Telescope (LT2.0) at Observatorio del Roque de los
Muchachos (La Palma, Spain), the 1.5m Ritchey-Chretien Telescope
(OSN1.5) at the Sierra Nevada Observatory (OSN, Spain), the 1.2m
Cassegrain telescope (TRE1.2) at the Michael Adrian Observatory
(Trebur, Germany), the 0.9m Ritchey-Chretien Telescope (OSN0.9) at
the OSN, the 0.9/0.6m Schmidt Teleskop Kamera (JENA0.9) at the
University Observatory Jena (Germany), and the 0.6m Cassegrain
telescope (PIW0.6) at the Institute of Astronomy of the Nicolaus
Copernicus University in Torun (Poland). The data were collected
between 2015 and 2021. The details of observations and data processing
are given in the source paper.
We also provide details on the out-of-transit monitoring for four
targets: HAT-P-10, HAT-P-17, HAT-P-44, and Qatar-6. The data were
collected with the PIW0.6 telescope between 2016 and 2019. Further
information is given in the source paper.
We also provide the new mid-transit times determined from our
ground-based light curves and from the TESS photometric time series.
The re-determined mid-transit times from literature data are also
given. For more details, see the paper.
