Accessible does not mean exploitable: HiPERCAM reveals the ultra-fast rotation of 2022 OB
Miguel R. Alarcon, Javier Licandro, Miquel Serra-Ricart +2
2022 OB is a sub-10-metre Apollo-type near-Earth asteroid whose orbital configuration placed it among the most dynamically accessible small bodies in near-Earth space, motivati…
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…
In-flight calibration of ESA Hera's HyperScout-H imager
G. P. Prodan, M. Popescu, J. de León +21
ESA's Hera space mission is on its way to the mission target, the binary asteroid (65803) Didymos. HyperScout-H, one of the instruments onboard Hera, is a hyperspectral imager oper…
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…
Why the Northern Hemisphere Needs a 30-40m Telescope and the Science at Stake: from Interstellar Visitors to Planetary Defence
J. de León, N. Pinilla-Alonso, P. Tanga +49
Small Solar system Objects (SSOs) preserve the physical, chemical, and dynamical signatures of the Sun's protoplanetary disk. Upcoming surveys will discover vast numbers of new obj…
Pre-perihelion detection of a wobbling high-latitude jet in the interstellar comet 3I/ATLAS
M. Serra-Ricart, J. Licandro, M. R. Alarcon
We present observations of the detection of a faint high-latitude jet in the inner coma of comet 3I/ATLAS that coincides with the broad plume detected in visible images along PA $2…
