Giant planets like hot Jupiters are the easiest planets to find, which is why the first discovered extrasolar planets are all giants. Three decades later, we now know over a thousand giant planets. However, there are still numerous mysteries around their formation, evolution, and their impact on their natal planetary systems. In this talk, I will introduce my group’s recent research on how special samples of giants would shed light on some of the clues in their formation and evolutionary processes, focusing on unique opportunities enabled by the TESS survey and ground-based radial velocity observations.
