A Leakage-Aware Multimodal Evaluation Framework for Early Intraoperative Acute Kidney Injury Prediction

Quang Minh Nguyen, Duc Minh Le, Ho Nhat Minh Nguyen +2

Postoperative acute kidney injury (AKI) after major non-cardiac surgery carries substantial morbidity, yet early intraoperative risk stratification remains difficult. In this retro…

POSEIDON III: The Aligned Orbit of the Hot Neptune Around the Hot Star WASP-195

Juan I. Espinoza-Retamal, Joshua N. Winn, Rafael Brahm +33

Stellar obliquities provide important clues as to the formation and migration histories of planetary systems, but measurements remain scarce for Neptune-mass planets, especially th…

Discovery and Characterization of the TOI-4468 Planetary System: A Transiting Hot Jupiter With a Lone Nearby Outer Companion

Joseph R. Livesey, Benjamin J. Hord, Juliette Becker +28

We report the discovery of two planets, a hot Jupiter and a nearby outer sub-Neptune, orbiting the star TOI-4468. This system is unique among the current exoplanet census in that i…

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…

POSEIDON I: The Dynamical Origins of Transiting Neptunes

Juan I. Espinoza-Retamal, Joshua N. Winn, Rafael Brahm +17

We present the first results from the POSEIDON survey, aimed at constraining the dynamical origins of transiting Neptunes through stellar obliquity measurements. We report Rossiter…

Hipparcos, Gaia, and RVs reveal that the radio emitting F star HD 220242 has an M dwarf companion, a likely source of the radio emission

Megan Delamer, Guðmundur Stefánsson, Suvrath Mahadevan +18

The detection of circularly polarized, low frequency radio emission offers the tantalizing possibility of the observation of interactions between stars and their possible substella…

Spectroscopic Characterization of LOFAR Radio-emitting M dwarfs

E. Koo, G. Stefansson, R. D. Kavanagh +20

Recent observations with the LOw Frequency ARray (LOFAR) have revealed 19 nearby M dwarfs showing bright circularly polarised radio emission. One of the possible sources of such em…

An Earth-Sized Planet in a 5.4h Orbit Around a Nearby K dwarf

Kaya Han Taş, Gudmundur Stefansson, Syarief N. M. Fariz +25

We present the discovery and confirmation of the ultra-short period (USP) planet TOI-2431 b orbiting a nearby ( pc) late K star ( = $4109 \pm 28 \, {\rm…
