Description

Transit light-curve observations play important roles in the study of
exoplanetary systems as they enable the determination of physical and
orbital parameters of exoplanets through transit timing variations
(TTVs).
The TTV method is particularly powerful for detecting additional
low-mass planets within a system. In this work, we analyze 176 light
curves, including 132 from TESS and 12 from CHEOPS. The long baseline
TTV provides constraints on the existence of additional planets. This
gives us an opportunity to investigate possible new planets around the
hot Jupiter WASP-18 b.
