The Mysterious Inspiral of WASP-12b: Why Obliquity Tides Cannot Drive Orbital Decay
Caleb Lammers, Yubo Su, Joshua N. Winn
WASP-12b's orbit is decaying, for unknown reasons. The planet's period is shrinking more rapidly than can be attributed to equilibrium tides or dynamical tides in a main-sequence s…
Constraining Tidal Migration with the Hot Jupiter Population
Linhao Ma, Yubo Su, Samuel W. Yee +3
Hot Jupiters with orbital periods shorter than a few days have probably been affected by tidal orbital migration. We develop an analytical framework for constraining tidal migratio…
POSEIDON III: The Aligned Orbit of the Hot Neptune Around the Hot Star WASP-195
Juan I. Espinoza-Retamal, Joshua N. Winn, Rafael Brahm +33
Stellar obliquities provide important clues as to the formation and migration histories of planetary systems, but measurements remain scarce for Neptune-mass planets, especially th…
Constraining the Planetary Obliquity Distribution of Warm Jupiters
Caleb Lammers, Joshua N. Winn
Warm Jupiters are an intriguing class of planets with uncertain origins. Their planetary obliquities could help distinguish between different formation pathways: planet-planet scat…
POSEIDON II: The Anti-Aligned Orbit of the Warm Neptune TOI-1710 A b
Juan I. Espinoza-Retamal, Hareesh Bhaskar, Joshua N. Winn +7
We present an observation of the Rossiter-McLaughlin effect for the TOI-1710 system with the NEID spectrograph on the WIYN 3.5 m telescope. The system hosts a warm Neptune ($P\sim2…
TTV-Not-So-Fast: Uniqueness and Degeneracy in Perturbing Planet Parameters
Caleb Lammers, Joshua N. Winn
Nontransiting planets can reveal themselves through transit timing variations (TTVs), but inferring the properties of the perturbing planet is a highly degenerate inverse problem.…
