A Pair of Warm Saturn-mass Planets near the 2:1 Mean Motion Resonance around TOI-3850

Sean Collins, Michelle Kunimoto, Nicolas B. Cowan +24

Warm Jupiters, with orbital periods of -- and radii exceeding , are a relatively understudied class of exoplanets occupying the parameter space bet…

The Occurrence Rate of Nearby Planetary Companions to Hot Jupiters

Lizhou Sha, Andrew M. Vanderburg, Chelsea X. Huang +33

The paper measures how often hot Jupiters have nearby transiting companion planets using TESS data, finding an occurrence rate of about 8%, which informs theories of hot‑Jupiter fo…

The GAPS programme at TNG: LXXVI. TOI-1533: a compact system hosting a super-Neptune-mass pair with disparate radii

G. Mantovan, V. Nascimbeni, S. Desidera +49

The present-day architecture of planetary systems contains information about their formation and migration histories. The origin of hot Jupiters (HJs, P 10 d, $R_{\rm p}…

TOI-6884b: A low-mass brown dwarf transiting a slightly evolved star

Akanksha Khandelwal, Shubhendra Nath Das, Rishikesh Sharma +42

We report the discovery of a low-mass transiting brown dwarf orbiting TOI-6884 (TIC~156514476, ) from NASA's \textit{Transiting Exoplanet Survey Satellite} (\text…

Observing a 542-day transiting giant with large TTVs: The 2025 transit of HIP 41378 f and new constraints on the outer system

Pietro Leonardi, Alexandre Santerne, Luca Borsato +27

Characterizing long-period transiting exoplanets is inherently challenging due to the rarity and long duration of transit events. Yet, these systems provide unique insights into pl…

TOI-7169 b: A Hot Jupiter Transiting a Metal-Poor Star

Joshua D. Simon, Joseph E. Rodriguez, Jhon Yana Galarza +38

Most known planets are found around metal-rich host stars, which has made it difficult to determine whether a lower metallicity limit for planet formation exists and how the proper…
