Euclid: Asteroid rotation periods from the Euclid Ecliptic Survey
B. Y. Irureta-Goyena, B. Altieri, J. -P. Kneib +142
The Euclid Ecliptic Survey was conducted during the calibration phase of the mission, 23-31 December 2023, as a campaign to study Solar System objects. We used data from this surve…
A dedicated survey of fast-rotating near-Earth asteroids with the Two-meter Twin Telescope. I. Observational strategy and first results
Miguel R. Alarcon, Javier Licandro, Miquel Serra-Ricart
The rotational properties of small near-Earth asteroids (NEAs) provide crucial insights into their internal structure and collisional history. However, systematic surveys targeting…
Pan-STARRS follow-up of the gravitational-wave event S250818k and the lightcurve of SN 2025ulz
J. H. Gillanders, M. E. Huber, M. Nicholl +30
Kilonovae are the scientifically rich, but observationally elusive, optical transient phenomena associated with compact binary mergers. Only a handful of events have been discovere…
Assessing interstellar comet 3I/ATLAS with the 10.4 m Gran Telescopio Canarias and the Two-meter Twin Telescope
R. de la Fuente Marcos, M. R. Alarcon, J. Licandro +8
Context. Theories of the formation and evolution of small bodies in planetary systems predict that they may escape into interstellar space at any time. After having characterized j…
Size and shape of the trans-Neptunian object (470316) 2007 OC10: Comparison with thermal data
J. M. Gómez-Limón, R. Leiva, J. L. Ortiz +40
The shapes of only 12 trans-Neptunian objects have been directly measured, offering crucial insights into their internal structure. These properties are strongly connected to the p…
Shape and spin-state model of tumbling asteroid (319) Leona
J. Äurech, J. L. Ortiz, M. Ferrais +14
Stellar occultations by asteroids observed from several stations are routinely used to reconstruct the asteroid's sky-plane projections. Together with the asteroid's shape model re…
