Abstract:
We present the results of our search for nearby planetary companions
of transiting hot Jupiters in 12 planetary systems: HAT-P-24,
HAT-P-39, HAT-P-42, HAT-P-50, KELT-2, KELT-15, KELT-17, WASP-23,
WASP-63, WASP-76, WASP-79, and WASP-161. Our analysis was based on
multi-sector time-series photometry from the Transiting Exoplanet
Survey Satellite and precise transit timing data sets. We detected no
additional transiting planets down to the 2-4 Earth radii regime. For
ten hot Jupiters, no departure from linear transit ephemerides was
observed. Whilst we refute long-term variations of the orbital period
for WASP-161 b, which were claimed in the literature, we notice a
tentative hint of the orbital period shortening for WASP-79 b. In
addition, we spot a short-period transit timing variation for
KELT-2A b with the characteristics typical of the so-called exomoon
corridor. We conclude, however, that further observations are required
to confirm these findings.

examined planets: HAT-P-24 b, HAT-P-39 b, HAT-P-42 b, HAT-P-50 b,
KELT-2A b, KELT-15 b, KELT-17 b, WASP-23 b, WASP-63 b, WASP-76A b,
WASP-79 b, and WASP-161 b.
