Contact binary asteroid (153201) 2000 WO107: rotation, shape model, and density
Yurij Krugly, Oleksiy Golubov, Ihor Kyrylenko +10
We combine different methods to investigate the rotation, determine the shape and estimate the density of near-Earth asteroid (153201) 2000 WO. We carried out photometric o…
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…
Photometry of the Didymos system across the DART impact apparition
Nicholas Moskovitz, Cristina Thomas, Petr Pravec +78
On 26 September 2022, the Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the satellite of binary near-Earth asteroid (65803) Didymos. This demonstrated the…
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…
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…
Potential asteroid discoveries by the ESA Gaia mission: Results from follow-up observations
B. Carry, W. Thuillot, F. Spoto +42
Since July 2014, the ESA Gaia mission has been surveying the entire sky down to magnitude 20.7 in the visible. In addition to the millions of stars, thousands of Solar System Objec…
A satellite orbit drift in binary near-Earth asteroids (66391) 1999 KW4 and (88710) 2001 SL9 -- Indication of the BYORP effect
P. Scheirich, P. Pravec, P. Kušnirák +34
We obtained thorough photometric observations of two binary near-Earth asteroids (66391) Moshup = 1999 KW4 and (88710) 2001 SL9 taken from 2000 to 2019 and derived physical and dyn…
Long-term photometric monitoring of the dwarf planet (136472) Makemake
T. A. Hromakina, I. N. Belskaya, Yu. N. Krugly +17
We studied the rotational properties of the dwarf planet Makemake. The photometric observations were carried out at different telescopes between 2006 and 2017. Most of the measurem…
Asteroid pairs: a complex picture
P. Pravec, P. Fatka, D. Vokrouhlický +45
We studied 93 asteroid pairs. We estimated times elapsed since separation of pair members that are between 7*10^3 and a few 10^6 yr. We derived the rotation periods for all the pri…

J. Durech, D. Vokrouhlicky, P. Pravec +22
The rotation states of small asteroids are affected by a net torque arising from an anisotropic sunlight reflection and thermal radiation from the asteroids' surfaces. On long time…
