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…

TOI-2005b: An Eccentric Warm Jupiter in Spin-Orbit Alignment

Allyson Bieryla, Jiayin Dong, George Zhou +36

We report the discovery and characterization of TOI-2005b, a warm Jupiter on an eccentric (e~0.59), 17.3-day orbit around a V_mag = 9.867 rapidly rotating F-star. The object was de…

Characterization of seven transiting systems including four warm Jupiters from SOPHIE and TESS

N. Heidari, G. H'ebrard, E. Martioli +65

We present the study of seven systems, three of which TOI-2295, TOI-2537, and TOI-5110 are newly discovered planetary systems. Through the analysis of TESS photometry, SOPHIE radia…

TOI-4504: Exceptionally large Transit Timing Variations induced by two resonant warm gas giants in a three planet system

Michaela Vítková, Rafael Brahm, Trifon Trifonov +24

We present a joint analysis of TTVs and Doppler data for the transiting exoplanet system TOI-4504. TOI-4504 c is a warm Jupiter-mass planet that exhibits the largest known transit…

Three Warm Jupiters orbiting TOI-6628, TOI-3837, TOI-5027 and one sub-Saturn orbiting TOI-2328

Marcelo Tala Pinto, Andrés Jordán, Lorena Acuña +35

We report the discovery and characterization of three new transiting giant planets orbiting TOI-6628, TOI-3837 and TOI-5027, and one new warm sub-Saturn orbiting TOI-2328, whose tr…

TESS Giants Transiting Giants. VII. A Hot Saturn Orbiting an Oscillating Red Giant Star

Nicholas Saunders, Samuel K. Grunblatt, Daniel Huber +26

We present the discovery of TOI-7041 b (TIC 201175570 b), a hot Saturn transiting a red giant star with measurable stellar oscillations. We observe solar-like oscillations in TOI-7…
