Dynamical Tides during High-Eccentricity Migration produces the Hot Jupiter Pile-up, Neptune Ridge, and Neptune Desert
J. J. Zanazzi, Morgan MacLeod, Marta L. Bryan +1
The period distribution of hot gaseous exoplanets depends strongly on mass. Clustering between the orbital periods of 3 to 5-6 days is seen for sub-Saturns ("Neptune ri…
Seismic Oscillations Excited by Giant Impacts in Directly-Imaged Giant Planets
J. J. Zanazzi, Eugene Chiang, Yifan Zhou
The radii and masses of many giant exoplanets imply their interiors each contain more than 100 of solids. A large metal content may arise when a giant planet grows…
Spin and Obliquity Evolution of Hot Jupiter Hosts from Resonance Locks
J. J. Zanazzi, Eugene Chiang
When a hot Jupiter orbits a star whose effective temperature exceeds 6100 K, its orbit normal tends to be misaligned with the stellar spin axis. Cooler stars typically have s…
Concealing Circumbinary Planets with Tidal Shrinkage
Saahit Mogan, J. J. Zanazzi
Of the 14 transiting planets that have been detected orbiting eclipsing binaries ('circumbinary planets'), none have been detected with stellar binary orbital periods shorter than…
