Humanity's search for Earth analogs is enriched by the fact that Earth-like planets do not form in isolation. The interplay between Earth-like planets and their siblings is an emerging new research topic. A prevalent pattern that represents one of the most common modes of planet formation is that planets in the same system tend to have similar sizes and regular orbital spacing, like...
We learned from NASA’s Kepler mission that small inner planets are common around Sun-like stars (50–100%). Separately, ground-based radial velocity (RV) surveys have shown that long-period gas giants are somewhat rare (~16%). To find the conditional occurrence of distant giants in systems with a close-in small planet, I conducted the Distant Giants Survey, a three-year RV search for giant...
Unveiling the architecture of planetary systems is crucial for understanding how planets form and migrate. In this talk, I investigate the occurrence rate of Cold Jupiters (CJs) in systems that host inner Small Planets (SPs), aimed at understanding if giant planets shield or disrupt their smaller inner siblings. I will present results based on an extensive dataset of over 5000 radial...
The connection between outer gas giants and inner super-Earths reflects their formation and evolutionary history. Past work exploring this link has suggested a tentative positive correlation between these two populations, but these studies were limited by small sample sizes and in some cases sample biases. In this talk I will highlight my recent collaborations with Eve Lee where we take a new...
The discovery of planets orbiting at less than 1 au from their host star and less massive than Saturn in various exoplanetary systems revolutionized our theories of planetary formation. The fundamental question is whether these close-in low-mass planets could have formed in the inner disc interior to 1 au, or whether they formed further out in the planet-forming disk and migrated inwards....
