Interstellar objects (ISOs) provide direct constraints on the composition and evolution of extrasolar planetary systems. As the third confirmed ISO, comet 3I/ATLAS offers a rare op…
The spin state of asteroid Apophis and a prediction of its change during the 2029 close encounter with Earth
J. Durech, D. Vokrouhlicky, P. Pravec +23
On April 13, 2029, the asteroid Apophis will pass near Earth at a geocentric distance of about 38,000 km. Numerical models have suggested that the post-encounter spin state will cr…
A high geometric albedo and small size of the Haumea cluster member (24835) 1995 SM55 from a stellar occultation and photometric observations
J. L. Ortiz, N. Morales, B. Sicardy +98
Trans-Neptunian objects (TNOs) are among the most ancient bodies of the solar system. Understanding their physical properties is key to constraining their origin and the evolution…
Update of the CODE catalogue and some aspects of the dynamical status of Oort Cloud comets
Piotr A. Dybczyński, Małgorzata Królikowska
The outer Solar System is believed to host a vast reservoir of long-period comets (LPCs), but our understanding of their spatial distribution and dynamical history remains limited…
Temporal Evolution of the Third Interstellar Comet 3I/ATLAS: Spin, Color, Spectra and Dust Activity
T. Santana-Ros, O. Ivanova, S. Mykhailova +7
We aim to characterize the physical and activity properties of the interstellar comet 3I/ATLAS through spectroscopic and photometric observations during the first month after its d…
A catalog of near-IR absolute magnitudes of Solar System small bodies
Alvaro Alvarez-Candal, Juan Luis Rizos, Milagros Colazo +5
Context. Phase curves of small bodies are useful tools to obtain their absolute magnitudes and phase coefficients. The former relates to the object's apparent brightness, while the…
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-…
Secondary impact debris in the Didymos system: what could be observed by Hera?
Krzysztof Langner, Elena Martellato, Robert Luther +2
We investigate the effects of low--velocity impacts of rocks and boulders, originally released after the DART impact, on the surface of Didymos and the dynamics of dust particles r…
Assessing the detection of the Yarkovsky effect using Gaia DR3 and FPR catalogues
Karolina Dziadura, Przemysław Bartczak, Dagmara Oszkiewicz
The primary objective of this study was to utilize the newest Gaia FPR catalogue containing ultra-precise asteroid astrometry spanning over 66 months to detect the Yarkovsky effect…
Lunar ore geology and feasibility of ore mineral detection using a far-IR spectrometer
Jakub Ciazela, Jaroslaw Bakala, Miroslaw Kowalinski +13
Lunar sulfides and oxides are a significant source of noble and base metals and will be vital for future human colonies' self-sustainability. Sulfide detection (pyrite and troilite…
Dynamical evolution of basaltic asteroids outside the Vesta family in the inner main belt
Volodymyr Troianskyi, Pawel Kankiewicz, Dagmara Oszkiewicz
Basaltic V-type asteroids are leftovers from the formation and evolution of differentiated planetesimals. They are thought to originate from mantles and crusts of multiple differen…
Asteroids seen by JWST-MIRI: Radiometric Size, Distance and Orbit Constraints
T. G. Müller, M. Micheli, T. Santana-Ros +3
Infrared measurements of asteroids are crucial for the determination of physical and thermal properties of individual objects, and for the understanding of the small-body populatio…
The equilibrium shape of (65) Cybele: primordial or relic of a large impact?
M. Marsset, M. Brož, J. Vermersch +24
Cybele asteroids constitute an appealing reservoir of primitive material genetically linked to the outer Solar System, and the physical properties of the largest members can be rea…
Spectral analysis of basaltic asteroids observed by the Gaia space mission
Dagmara Oszkiewicz, Hanna Klimczak, Benoit Carry +4
There is a great deal of scientific interest in characterizing the basaltic asteroids (spectrally classified as V-types), as they are the key to understanding planetesimal formatio…
Asteroid spin-states of a 4 Gyr collisional family
D. Athanasopoulos, J. Hanus, C. Avdellidou +29
Families of asteroids generated by the collisional fragmentation of a common parent body have been identified using clustering methods of asteroids in their proper orbital element…
Physical properties of the trans-Neptunian object (38628) Huya from a multi-chord stellar occultation
P. Santos-Sanz, J. L. Ortiz, B. Sicardy +85
Within our international program to obtain accurate physical properties of trans-Neptunian objects (TNOs) we predicted a stellar occultation by the TNO (38628) Huya of the star Gai…
Asteroid phase curves using sparse Gaia DR2 data and differential dense light curves
E. Wilawer, D. Oszkiewicz, A. Kryszczyńska +10
The amount of sparse asteroid photometry being gathered by both space- and ground-based surveys is growing exponentially. This large volume of data poses a computational challenge…
