Multi-Wavelength Post-Perihelion Polarimetry of Interstellar Comet 3I/ATLAS
Zuri Gray, Galin Borisov, Ludmilla Kolokolova +15
We present new post-perihelion polarimetric observations of the third discovered interstellar object, 3I/ATLAS (C/2025 N1; hereafter 3I), obtained using FORS2 at the Very Large Tel…
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…
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…
NSF-DOE Vera C. Rubin Observatory Observations of Interstellar Comet 3I/ATLAS (C/2025 N1)
Colin Orion Chandler, Pedro H. Bernardinelli, Mario Jurić +305
We report on the observation and measurement of astrometry, photometry, morphology, and activityof the interstellar object 3I/ATLAS, also designated C/2025 N1 (ATLAS) with the NSF-…
High-Speed Boulders and the Debris Field in DART Ejecta
Tony L. Farnham, Jessica M. Sunshine, Masatoshi Hirabayashi +44
On 26 September 2022 the Double Asteroid Redirection Test (DART) spacecraft collided with Dimorphos, the moon of the near-Earth asteroid 65803 Didymos, in a full-scale demonstratio…
New evidence supporting past dust ejections from active asteroid (4015) Wilson-Harrington
Sunho Jin, Masateru Ishiguro, Jooyeon Geem +15
Context. (4015) Wilson-Harrington (hereafter, WH) was discovered as a comet in 1949 but has a dynamical property consistent with that of a near-Earth asteroid. Although there is a…
Macro-scale roughness reveals the complex history of asteroids Didymos and Dimorphos
Jean-Baptiste Vincent, Erik Asphaug, Olivier Barnouin +22
Morphological mapping is a fundamental step in studying the processes that shaped an asteroid surface. Yet, it is challenging and often requires multiple independent assessments by…
Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks
Theodore Kareta, Cristina Thomas, Jian-Yang Li +85
The impact of the DART spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos' orbit substantially, largely from the ejection of material. We present results fr…
Near to Mid-Infrared Spectroscopy of (65803) Didymos as observed by JWST: Characterization Observations Supporting the Double Asteroid Redirection Test
Andrew S. Rivkin, Cristina A. Thomas, Ian Wong +17
The Didymos binary asteroid was the target of the Double Asteroid Redirection Test (DART) mission, which intentionally impacted Dimorphos, the smaller member of the binary system.…
Momentum Transfer from the DART Mission Kinetic Impact on Asteroid Dimorphos
Andrew F. Cheng, Harrison F. Agrusa, Brent W. Barbee +66
The NASA Double Asteroid Redirection Test (DART) mission performed a kinetic impact on asteroid Dimorphos, the satellite of the binary asteroid (65803) Didymos, at 23:14 UTC on Sep…
Ejecta from the DART-produced active asteroid Dimorphos
Jian-Yang Li, Masatoshi Hirabayashi, Tony L. Farnham +61
Some active asteroids have been proposed to be the result of impact events. Because active asteroids are generally discovered serendipitously only after their tail formation, the p…
Basaltic material in the main belt: a tale of two (or more) parent bodies?
S. Ieva, E. Dotto, D. Lazzaro +5
The majority of basaltic objects in the main belt are dynamically connected to Vesta, the largest differentiated asteroid known. Others, due to their current orbital parameters, ca…
Photometric survey of 67 near-Earth objects
S. Ieva, E. Dotto, E. Mazzotta Epifani +9
The near-Earth object (NEO) population is a window into the original conditions of the protosolar nebula, and has the potential to provide a key pathway for the delivery of water a…
Spectral characterization of V-type asteroids - II. A statistical analysis
S. Ieva, E. Dotto, D. Lazzaro +3
In recent years several small basaltic V-type asteroids have been identified all around the main belt. Most of them are members of the Vesta dynamical family, but an increasingly l…
Short-term variability on the surface of (1) Ceres. A changing amount of water ice?
D. Perna, Z. Kaňuchová, S. Ieva +5
Context: The dwarf planet (1) Ceres - next target of the NASA Dawn mission - is the largest body in the asteroid main belt; although several observations of this body have been per…
Low delta-V near-Earth asteroids: A survey of suitable targets for space missions
S. Ieva, E. Dotto, D. Perna +7
In the last decades Near-Earth Objects (NEOs) have become very important targets to study, since they can give us clues to the formation, evolution and composition of the Solar Sys…
