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…
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…
Asteroid pairs: method validation and new candidates
Ihor Kyrylenko, Yurij N. Krugly, Oleksiy Golubov
An asteroid pair can be described as two asteroids with highly similar heliocentric orbits that are genetically related but not gravitationally bound. They can be produced by aster…
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…
Photometry of an unusual small distant object 2016 ND21
Tetiana Hromakina, Sergey Velichko, Irina Belskaya +2
We present the first-ever measurements of the surface colors and rotational properties of a recently discovered distant object in an unusual orbit 2016 ND21. In 2017, this object w…
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…
YORP and Yarkovsky effects in asteroids (1685) Toro, (2100) Ra-Shalom, (3103) Eger, and (161989) Cacus
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…
Multicolour modelling of SN 2013dx associated with GRB 130702A
A. A. Volnova, M. V. Pruzhinskaya, A. S. Pozanenko +13
We present optical observations of SN 2013dx, related to the Fermi burst GRB 130702A occurred at a redshift z = 0.145. It is the second-best sampled GRB-SN after SN~1998bw: the obs…
Obliquity dependence of the tangential YORP
P. Ševeček, O. Golubov, D. J. Scheeres +1
Context. Tangential YORP is a thermophysical effect that can alter the rotation rate of asteroids and is distinct from the "normal" YORP effect, but to date has only been studied f…
Physical models for the normal YORP and diurnal Yarkovsky effects
O. Golubov, Y. Kravets, Yu. N. Krugly +1
We propose an analytic model for the normal YORP and diurnal Yarkovsky effects experienced by a convex asteroid. Both the YORP torque and the Yarkovsky force are expressed as integ…
New and updated convex shape models of asteroids based on optical data from a large collaboration network
J. Hanuš, J. Ďurech, D. A. Oszkiewicz +165
Asteroid modeling efforts in the last decade resulted in a comprehensive dataset of almost 400 convex shape models and their rotation states. This amount already provided a deep in…
Tangential component of the YORP effect
Oleksiy Golubov, Yurij N. Krugly
This article discusses how re-emission of absorbed solar light by centimeter- to decimeter-sized structures on the surface of an asteroid can create a component of the recoil force…
A 3-dimensional model of tangential YORP
O. Golubov, D. J. Scheeres, Yu. N. Krugly
Tangential YORP, or TYORP, has recently been demonstrated to be an important factor in the evolution of an asteroid's rotation state. It is complementary to normal YORP, or NYORP,…
