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…
Some results of CCD-photometry of variable stars at the Astronomical Institute of Karazin Kharkiv National University
V. G. Shevchenko, D. O. Danylko, I. G. Slyusarev +1
We presented photometric observations for the one UV Ceti type and three W Ursae Majoris-type variable stars. The flare of the UV Ceti type star lasted about two hours, and the sta…
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…
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…
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…
Phase integral of asteroids
Vasilij G. Shevchenko, Irina N. Belskaya, Olga I. Mikhalchenko +6
The values of the phase integral q were determined for asteroids using (i) a numerical integration of the brightness phase functions over a wide phase-angle range and (ii) the rela…
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…
The binary near-Earth asteroid (175706) 1996 FG3 - An observational constraint on its orbital evolution
P. Scheirich, P. Pravec, S. A. Jacobson +23
Using our photometric observations taken between 1996 and 2013 and other published data, we derived properties of the binary near-Earth asteroid (175706) 1996 FG3 including new mea…
Analysis of the rotation period of asteroids (1865) Cerberus, (2100) Ra-Shalom, and (3103) Eger - search for the YORP effect
J. Durech, D. Vokrouhlicky, A. R. Baransky +28
The spin state of small asteroids can change on a long timescale by the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect, the net torque that arises from anisotropically scatter…
Multi-wavelength observations of afterglow of GRB 080319B and the modeling constraints
S. B. Pandey, A. J. Castro-Tirado, M. Jelínek +24
We present observations of the afterglow of GRB 080319B at optical, mm and radio frequencies from a few hours to 67 days after the burst. Present observations along with other publ…
