The Occurrence Rate of Nearby Planetary Companions to Hot Jupiters
The episode discusses a study titled "The Occurrence Rate of Nearby Planetary Companions to Hot Jupiters." The authors found that these massive planets, which are usually solitary, often have nearby companions. This stability challenges the old idea that such systems should be violently disrupted by gravity. The research uses TESS data and rigorous methodology to quantify how frequently these stable arrangements exist in nature.
