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…

PLATOSpec's first results: Three new transiting warm Jupiters from the WINE survey TIC 147027702, TIC 245076932 and TIC 87422071

Pavol Gajdoš, Rafael Brahm, Lorena Acuña-Aguirre +33

We report the discovery and characterisation of three transiting warm Jupiters: TIC 147027702b, TIC 245076932b and TIC 87422071b. These systems were initially identified as transit…

TIC65910228b: A single-transit discovery of a massive long-period warm Jupiter with TESS

Felipe I. Rojas, Rafael Brahm, Matías I. Jones +27

Context. Warm Jupiters are excellent case studies for the investigation of giant planet internal structures and formation theories. However, the sample of long-period transiting gi…

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…

A transiting hot Jupiter with two outer siblings orbiting an intermediate-mass post main-sequence star

Y. Reinarz, M. I. Jones, R. Brahm +15

Exoplanetary systems with multiple giant planets present an opportunity to understand planet formation, migration processes, and long-term system-wide dynamical interactions. In pa…

Detection and characterisation of a 106-day transiting Jupiter : TOI-2449 b / NGTS-36 b

S. Ulmer-Moll, S. Gill, R. Brahm +64

Only a handful of transiting giant exoplanets with orbital periods longer than 100 days are known. These warm exoplanets are valuable objects as their radius and mass can be measur…
