Discovery of an Inflated Hot Neptune and Its Formation from Jovian Mass Loss
Grant C. Weldon, Samuel W. Yee, Bradley M. S. Hansen +17
The production of Neptune-like planets with orbital periods of 3--6 days is challenging for conventional models of high-eccentricity migration. We present the discovery and charact…

Saving Doomed Planets: Mass Loss and Angular Momentum Return Boost Hot Jupiter Survival Rates
Grant C. Weldon, Bradley M. S. Hansen, Smadar Naoz
The existence of giant extrasolar planets on short-period orbits ("hot Jupiters") challenges planet formation theories because such planets are difficult to form close to the star.…

The cold Jupiter eccentricity distribution is consistent with EKL driven by stellar companions
Grant C. Weldon, Smadar Naoz, Bradley M. S. Hansen
The large eccentricities of cold Jupiters and the existence of hot Jupiters have long challenged theories of planet formation. A proposed solution to both of these puzzles is high-…
