Exploring the Properties and Demographics of Warm Jupiter Systems
Presented by Ismael Mireles, UNM
There are now over 5500 confirmed exoplanets, but many questions remain regarding how planets form and evolve. Despite over 2000 of these planets being part of multi-planet systems, none discovered so far resembles our own Solar System. Nonetheless, multi-planet systems are essential to probe planet formation and evolution. In particular, systems with warm gas giant planets are promising as these planets bridge the gap between the well-studied hot gas giant population and the cold gas giants in our solar system. The launch of the Transiting Exoplanet Survey Satellite (TESS) has led to the discovery of many warm gas giants, increasing the existing sample by more than 40%. Additionally, many of these orbit bright stars that are ideal for follow-up observations to characterize their masses, orbits, and atmospheres as well as to search for additional planets. I present my recent, current, and future work to detect and characterize these systems and study their demographics as well as to detect new companions to them that will improve our understanding on planet formation and evolution. I detail four specific warm Jupiter systems - TOI-4600, TOI-1670, TOI-201, and TOI-4127 - and describe what we have learned about them, and what we stand to learn with future observations.
