Planet-Planet Secular Migration Predicts a Stellar Obliquity-Period Anti-Correlation
Hareesh Gautham Bhaskar, Cristobal Petrovich, Diego J. Muñoz
Stellar obliquities provide a fossil record of hot Jupiter (HJ) migration. An emerging observational trend in single-star systems is that strongly misaligned HJs are largely confin…
A Cold and Super-Puffy Planet on a Prograde Orbit
Juan I. Espinoza-Retamal, Rafael Brahm, Cristobal Petrovich +36
We report the discovery of TOI-4507 b, a transiting sub-Saturn with a density 0.2 g/cm on a 105-day prograde orbit around a 700 Myr old F star. The transits were detected u…
The Spin-Orbit Alignment of 8 Warm Gas Giant Systems
Juan I. Espinoza-Retamal, Andrés Jordán, Rafael Brahm +9
Essential information about the formation and evolution of planetary systems can be found in their architectures -- in particular, in stellar obliquity () -- as they serve as a…
HATS-38 b and WASP-139 b join a growing group of hot Neptunes on polar orbits
Juan I. Espinoza-Retamal, Guðmundur Stefánsson, Cristobal Petrovich +9
We constrain the sky-projected obliquities of two low-density hot Neptune planets, HATS-38 b and WASP-139 b, orbiting nearby G and K stars using Rossiter-McLaughlin (RM) observatio…
The Aligned Orbit of the Eccentric Proto Hot Jupiter TOI-3362b
Juan I. Espinoza-Retamal, Rafael Brahm, Cristobal Petrovich +8
High-eccentricity tidal migration predicts the existence of highly eccentric proto-hot Jupiters on the "tidal circularization track," meaning that they might eventually become hot…
