| Abstract: |
There are now over 5000 confirmed exoplanets, but due to observational biases, 80% of them have orbital periods shorter than Mercury's 88-day period. As a result, there remain various questions regarding long-period exoplanets, such as their exact origins and distributions. I discuss how we use the Transiting Exoplanet Survey Satellite (TESS) alongside ground-based observatories to detect and characterize long-period planets. I will detail the techniques we use to determine the orbital periods of singly and doubly transiting planets detected by TESS and discuss how our discoveries will expand our knowledge of this less-explored region of parameter space. I also highlight a particular system, TOI 4600, which contains two long-period gas giants and discuss possible formation and evolution scenarios as well as prospects for future atmospheric characterization.
