Setting the Stage: The Early History of the Solar System

Antgona Segura, Rachel L. Smith, Myriam Telus +3

The paper reviews how the early solar system formed and how key organic molecules arose, using evidence from meteorites and observations of protoplanetary disks.

Stellar Multiplicity of M Dwarfs with Short-period Giant Planets, and the Characterization of TOI-5628Ab

Tianjun Gan, Alexandrine L'Heureux, Charles Cadieux +33

Binary stars are ubiquitous, yet it remains unclear how wide-orbit stellar companions influence the formation of hot Jupiters, particularly around M dwarfs. Here, we first report t…

Spin-Orbit Geometry of AU Mic b and c from Back-to-Back Transits Observed Contemporaneously with Magellan PFS, LCOGT, and CHEOPS

Zitao Lin, Gyula M. Szabó, Krzysztof Sz. Zieliński +37

Young planets offer a unique window into the early stages of planetary evolution. AU Mic is one of the nearest (9.8 pc) pre-main sequence stars (~20 Myr), hosting two transiting Ne…

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…

Comparing Results from Two Uniform Phase Curve Surveys

Emeline Decocq, Mark Swain, Lisa Dang +2

We present a comparison of the two most recent and comprehensive Spitzer phase curve studies - Dang et al. (2025) and Swain et al. (2025) - which report analyses of the Spitzer 4.5…
