Abstract:
The presence of another planetary companion in a transiting exoplanet
system can impact its transit light curve, leading to sinusoidal
transit-timing variations (TTV). By utilizing both χ2 and rms
analysis, we have combined the TESS observation data with an N-body
simulation to investigate the existence of an additional planet in the
system and put a limit on its mass. We have developed CMAT, an
efficient and user-friendly tool for fitting transit light curves and
calculating TTV with a theoretical period, based on which we can give
a limit on its hidden companion's mass. We use 260 hot Jupiter systems
from the complete TESS data set to demonstrate the use of CMAT. Our
findings indicate that, for most systems, the upper mass limit of a
companion planet can be restricted to several Jupiter masses. This
constraint becomes stronger near resonance orbits, such as the 1:2,
2:1, 3:1, and 4:1 mean-motion resonance, where the limit is reduced to
several Earth masses. These findings align with previous studies
suggesting that a lack of companion planets with resonance in hot
Jupiter systems could potentially support the high-eccentricity
migration theory. Additionally, we observed that the choice between
χ2 or rms method does not significantly affect the upper limit on
companion mass; however, χ2 analysis may result in weaker
restrictions but is statistically more robust compared to rms analysis
in most cases.
Description:
The data for this study are taken from the Transiting Exoplanet Survey
Satellite (TESS) observations. We select transiting hot Jupiters
observed by TESS based on the following criteria: an orbital period of
less than 10 days and a mass greater than 0.3MJ. This results in a
sample of 260 hot Jupiter systems.
