A 43 day transiting Neptune and two 25 day Saturns from TESS, NGTS and ASTEP
Alicia Kendall, Solène Ulmer-Moll, Samuel Gill +53
Beyond orbital periods of 10 days, there is a dearth of known transiting gas giants. On longer orbits, planets are less affected by their host star, and become ideal probes of plan…
Rapid-response characterization of near-Earth asteroid 2024 YR4 during a Torino Scale 3 alert
Maxime Devogèle, Olivier R. Hainaut, Marco Micheli +32
On 27 December 2024, near-Earth object (NEO) 2024 YR was discovered by the ATLAS survey and identified as a virtual impactor. A few weeks later, it eventually reached level 3 o…
High five from ASTEP: Three validated planets and two eclipsing binaries in a diverse set of long-period candidates
Erika Rea, Maximilian N. Günther, George Dransfield +44
We present the analysis of five long-period TESS Objects of Interest (TOIs), all orbiting Sun-like stars, with orbital periods exceeding one month. Initially identified by the Tran…
A Cold and Super-Puffy Planet on a Prograde Orbit
Juan I. Espinoza-Retamal, Rafael Brahm, Cristobal Petrovich +36
We report the discovery of TOI-4507 b, a transiting sub-Saturn with a density 0.2 g/cm on a 105-day prograde orbit around a 700 Myr old F star. The transits were detected u…
Extreme Negative Polarisation of New Interstellar Comet 3I/ATLAS
Zuri Gray, Stefano Bagnulo, Galin Borisov +13
We present the first polarimetric observations of the third discovered interstellar object, 3I/ATLAS (C/2025 N1), obtained pre-perihelion with FORS2/VLT, ALFOSC/NOT, and FoReRo2/RC…
Cryoscope: A Cryogenic Infrared Survey Telescope in Antarctica
Mansi M. Kasliwal, Nicholas Earley, Roger Smith +58
We present Cryoscope--a new 50 deg field-of-view, 1.2 m aperture, survey telescope to be located at Dome C, Antarctica. Cryoscope has an innovative optical-thermal d…
