Orbital Decay of the Ultra-Hot Jupiter TOI-2109b: Tidal Constraints and Transit-Timing Analysis
Jaime A. Alvarado-Montes, Mario Sucerquia, Jorge I. Zuluaga +1
TOI-2109b is the ultra-hot Jupiter with the shortest orbital period (hr) yet discovered. At this close distance, strong tidal interactions can produce a significant excha…
Searching for GEMS: Confirmation of TOI-5573b, a Cool, Saturn-like Planet Orbiting An M-dwarf
Rachel B Fernandes, Shubham Kanodia, Megan Delamer +35
We present the confirmation of TOI-5573b, a Saturn-sized exoplanet on an 8.79-day orbit around an early M-dwarf (3790 K, 0.59 R, 0.61 M, 12.30 J mag). TOI-5573b has a…
Origins of Super Jupiters: TOI-2145b Has a Moderately Eccentric and Nearly Aligned Orbit
Jiayin Dong, Ashley Chontos, George Zhou +15
Super Jupiters are giant planets with several Jupiter masses. It remains an open question whether these planets originate with such high masses or grow through collisions. Previous…
Gaia-4b and 5b: Radial Velocity Confirmation of Gaia Astrometric Orbital Solutions Reveal a Massive Planet and a Brown Dwarf Orbiting Low-mass Stars
Gudmundur Stefansson, Suvrath Mahadevan, Joshua Winn +31
Gaia astrometry of nearby stars is precise enough to detect the tiny displacements induced by substellar companions, but radial velocity data are needed for definitive confirmation…
Searching for GEMS: TOI-5688 A b, a low-density giant orbiting a high-metallicity early M-dwarf

We present the discovery of a low-density planet orbiting the high-metallicity early M-dwarf TOI-5688 A b. This planet was characterized as part of the search for transiting giant…
The missing rings around Solar System moons
Mario Sucerquia, Jaime A. Alvarado-Montes, Jorge I. Zuluaga +3
Rings are complex structures surrounding giant planets and some minor bodies in the Solar System. While some formation mechanisms could also potentially foster their existence arou…
A general polarimetric model for transiting and non-transiting ringed exoplanets
Allard K. Veenstra, Jorge I. Zuluaga, Jaime A. Alvarado-Montes +2
