Abstract: Multiplanet systems provide a rich ground to test theories of planetary system formation, understand planetary system architectures, and perform comparative exoplanetology. I present our survey of the TESS Object of Interest (TOI) catalog, focusing on a targeted search for multiplanet systems. Our methodology entailed recovering known TOIs from TESS Full-Frame Images (FFIs) for a target star and searching for up to three additional planet candidates. I discuss the seven new multiplanet systems identified through this work, their notable characteristics and potential for follow-up, with a special focus on two intriguing systems: one featuring five planet candidates, and another harboring one hot Jupiter with a close-in, outer giant companion—a rare occurrence.
