Hot Jupiters, giant planets on tight orbits, have been perceived as loners that are devoid of planetary companions in close orbital proximity. This observation is interpreted as an output of a violent formation path through the high eccentricity tidal migration, which is destructive for primordial multi-planetary architecture. However, recent discoveries based on space-borne photometry have revealed that some of these giant planets do have low-mass planet companions in close orbits. This finding speaks in favour of a quiescent formation scenario through disk migration. Understanding the occurrence rate of these systems could offer new insights into the origins of hot Jupiters, a question that has puzzled planetary formation and evolution theory for a long time. Our project uses the transit detection method to search for nearby transiting planetary companions to hot Jupiters using data from the Transiting Exoplanet Survey Satellite. In this brief discussion, we share the first results of our search.
