TOI-3862 b: A dense super-Neptune deep in the hot Neptune desert

Ilaria Carleo, Amadeo Castro-González, Enric Pallé +61

The structure and evolution of close-in exoplanets are shaped by atmospheric loss and migration processes, which give rise to key population features such as the hot Neptune desert…

Precise mass and radius determination for two new and one known Neptune-sized planets around G Dwarf hosts

Ilaria Carleo, Grzegorz Nowak, Felipe Murgas +56

As part of the KESPRINT collaboration, we present the discovery and characterization of three exoplanets in the sub-Neptune to super-Neptune regime, spanning key regions of the exo…

TOI-1438: A rare system with two short-period sub-Neptunes and a tentative long-period Jupiter-like planet orbiting a K0V star

Carina M. Persson, Emil Knudstrup, Ilaria Carleo +44

We present the detection and characterisation of the TOI-1438 multi-planet system discovered by TESS. We collected a series of follow-up observations including high-spectral resolu…

ExoMiner++: Enhanced Transit Classification and a New Vetting Catalog for 2-Minute TESS Data

Hamed Valizadegan, Miguel J. S. Martinho, Jon M. Jenkins +24

We present ExoMiner++, an enhanced deep learning model that builds on the success of ExoMiner to improve transit signal classification in 2-minute TESS data. ExoMiner++ incorporate…

TOI-2458 b: A mini-Neptune consistent with in situ hot Jupiter formation

Ján Šubjak, Davide Gandolfi, Elisa Goffo +33

We report on the discovery and spectroscopic confirmation of TOI-2458 b, a transiting mini-Neptune around an F-type star leaving the main-sequence with a mass of $M_\star=1.05 \pm…

HD 119130 b is not an "ultra-dense" sub-Neptune

Joseph M. Akana Murphy, Rafael Luque, Natalie M. Batalha +13

We present a revised mass measurement for HD 119130 b (aka K2-292 b), a transiting planet ( days, ) orbiting a chro…
