We present TOI-6981 b, a cold (Teq= 170.0 +/-4.5 K, assuming an Earth-like albedo) sub-Neptune (Rb=2.40+/-0.10 R_oplus) on a 60.8 day orbit around around its M4-type host star (R*=…
TS23/McDonald and FIES/NOT strike again. Two new warm Jupiter systems and outer companions in a third
E. Knudstrup, D. Gandolfi, W. D. Cochran +29
Warm Jupiters (gas giant planets with orbital periods of P8-200 d) are thought to be largely unaffected by the tidal interactions that can erase information about the dynamic…
Assessing the Impact of High-Resolution Imaging on Statistical Validation of TESS Planet Candidates
Michael Collier, Steven Giacalone, Brian Derfer +38
High-resolution imaging is widely used to constrain false-positive scenarios in exoplanet validation, but it is a finite follow-up resource that reaches only a subset of candidates…

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…
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…
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…
Size, shape, density, and atmospheric limit of (50000) Quaoar revealed from 14 years of stellar occultation
Giuliano Margoti, Felipe Braga-Ribas, José Luis Ortiz +173
We present results from 28 stellar occultations by the large Trans-Neptunian Object (50000) Quaoar registered between 2018 and 2025. By performing a joint analysis of this occultat…
ASTEP confirmation of a pair of long-period Jupiter-sized planets with extremely low densities transiting TOI-791
Georgina Dransfield, Antoine C. Petit, Amaury H. M. J. Triaud +45
Gas giant planets with periods orbiting Sun-like stars are a relatively uncommon outcome of planetary formation, and key questions about the nature and form…
Uncovering the Rapidly Evolving Orbits of the Dynamic TOI-201 System
Ismael Mireles, Solène Ulmer-Moll, Donald Liveoak +47
Studying planetary interactions in exoplanet systems informs theories of planet formation and evolution, providing essential context for understanding our own solar system. We comb…
A gem system with a lava world and a habitable zone sub-Neptune orbiting TOI-1752
A. Peláez-Torres, F. J. Pozuelos, G. Morello +47
The Transiting Exoplanet Survey Satellite (TESS) has delivered a large number of transiting planet candidates around nearby stars by identifying periodic decreases in stellar brigh…
TOI-4616 b: a benchmark Earth-sized planet transiting a nearby M4 dwarf
F. Zong Lang, B. O. Demory, Y. Gomez Maqueo Chew +44
Rocky exoplanets are particularly abundant around M-type stars. Their small radii and low luminosities provide favourable conditions for detecting transiting terrestrial planets an…
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…
A Panchromatic JWST Spectrum of a Giant Starspot on the Fully Convective M-dwarf TOI-3884
C. A. Murray, L. Garcia, B. V. Rackham +18
TOI-3884 b is a rare super-Neptune transiting a fully convective M dwarf that hosts a persistent giant polar spot. Because the planet occults this active region during every transi…
