The Inbound Gas and Dust Evolution of Interstellar Comet 3I/ATLAS from Optical Spectroscopy and Multi-band Photometry
Toni Santana-Ros, Alexey Sergeyev, Oleksandra Ivanova +9
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…
Size, albedo and rotational period of the Hayabusa2# target (98943) 2001 CC21
S. Fornasier, E. Dotto, P. Panuzzo +8
This study aims to determine the size, albedo and rotational period of (98943) 2001 CC21, target of the Hayabusa2 extended mission, using thermal data from the Spitzer Space telesc…
Secular change in the spin states of asteroids due to radiation and gravitation torques. New detections and updates of the YORP effect
J. Ďurech, D. Vokrouhlický, P. Pravec +21
The rotation state of small asteroids is affected in the long term by perturbing torques of gravitational and radiative origin (the YORP effect). Direct observational evidence of t…
A large topographic feature on the surface of the trans-Neptunian object (307261) 2002 MS measured from stellar occultations
F. L. Rommel, F. Braga-Ribas, J. L. Ortiz +201
This work aims at constraining the size, shape, and geometric albedo of the dwarf planet candidate 2002 MS4 through the analysis of nine stellar occultation events. Using multichor…
Physical modelling of near-Earth asteroid (23187) 2000 PN9 with ground-based optical and radar observations
L. Dover, S. C. Lowry, A. Rożek +19
We present a physical model and spin-state analysis of the potentially hazardous asteroid (23187) 2000 PN9. As part of a long-term campaign to make direct detections of the YORP ef…
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…
Polarimetry of M-type asteroids in the context of their surface composition
I. Belskaya, A. Berdyugin, Yu. Krugly +9
Aims. We aim to investigate how polarimetric observations can improve our understanding of the nature and diversity of M/X-type asteroids. Methods. Polarimetric observations of the…
Observations of asteroid magnitude-phase relations at the Kharadze Abastumani Astrophysical Observatory
V. G. Shevchenko1, R. Ya. Inasaridze, Yu. N. Krugly +6
In frame of an implementation of the cooperative program studying of asteroids between the Kharadze Abastumani Astrophysical Observatory and the Astronomical Institute of V.N. Kara…
Rotation acceleration of asteroids (10115) 1992 SK, (1685) Toro, and (1620) Geographos due to the YORP effect
J. Durech, D. Vokrouhlicky, P. Pravec +28
The rotation state of small asteroids is affected by the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect, which is a net torque caused by solar radiation directly reflected and…
Photometry of selected outer main belt asteroids
V. Shevchenko, O. Mikhalchenko, I. Belskaya +17
We present new photometric observations for twelve asteroids ((122) Gerda, (152) Atala, (260) Huberta, (665) Sabine, (692) Hippodamia, (723) Hammonia, (745) Mauritia, (768) Struvea…
Small solar system objects on highly inclined orbits: Surface colours and lifetimes
T. Hromakina, I. Belskaya, Yu. Krugly +9
Less than one percent of the discovered small solar system objects have highly inclined orbits (), and revolve around the Sun on near-polar or retrograde orbits. The…
Rotational variation of the linear polarisation of the asteroid (3200) Phaethon as evidence for inhomogeneity in its surface properties
G. Borisov, M. Devogèle, A. Cellino +23
Asteroid (3200) Phaethon is a Near-Earth Apollo asteroid with an unusual orbit that brings it closer to the Sun than any other known asteroid. Its last close approach to the Earth…
The phase-polarization curve of asteroid (3200) Phaethon
M. Devogèle, A. Cellino, G. Borisov +10
A multi-colour phase-polarization curve of asteroid (3200)~Phaethon has been obtained during the December 2017 apparition by merging measurements taken at the observing station of…
