Modeling of the Yarkovsky effect. I. Thermal dependence
O. Golubov, O. Mikhalchenko, V. Lipatova +1
We investigate how the Yarkovsky effect created by one flat surface element on the asteroid depends on the thermal parameter. Then we integrate the Yarkovsky force over the surface…
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…
Analytic theory for the tangential YORP produced by the asteroid regolith
Oleksiy Golubov, Veronika Lipatova
The tangential YORP effect is a radiation pressure torque produced by asymmetric thermal emission by structures on the asteroid surface. As such structures, previous works consider…
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…
Limiting behavior of asteroid obliquity and spin using a semi-analytic thermal model of the YORP effect
Oleksiy Golubov, Vladyslav Unukovych, Daniel J. Scheeres
The Yarkovsky--O'Keefe--Radzievskii--Paddack (YORP) effect governs the spin evolution of small asteroids. The axial component of YORP, which alters the rotation rate of the asteroi…
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…
Evolution of an asteroid family under YORP, Yarkovsky and collisions
Francesco Marzari, Alessandro Rossi, Oleksiy Golubov +1
Any population of asteroids, like asteroid families, will disperse in semi-major axis due to the Yarkovsky effect. The amount of drift is modulated by the asteroid spin state evolu…
Origami launcher
Oryna Ivashtenko, Polina Kofman, Oleksiy Golubov +1
The article studies the elastic and locomotive properties of Miura-ori-type paper origami. The mechanics of a single paper crease is studied experimentally, and its non-elastic pro…
Detection of Rotational Acceleration of Bennu using HST Lightcurve Observations
Michael C. Nolan, Ellen S. Howell, Daniel J. Scheeres +7
We observed the near-Earth asteroid (101955) Bennu from the ground in 1999 and 2005, and with the Hubble Space Telescope in 2012, to constrain its rotation rate. The data reveal an…
Systematic structure and sinks in the YORP effect
Oleksiy Golubov, Daniel J. Scheeres
There is a correlation between the components of the YORP effect of most asteroids, which drives the obliquity and spin rate of the affected bodies in a consistent pattern. This al…
A new equilibrium state for singly synchronous binary asteroids
Oleksiy Golubov, Vladyslav Unukovych, Daniel J. Scheeres
The evolution of rotation states of small asteroids is governed by the YORP effect, nonetheless some asteroids can stop their YORP evolution by attaining a stable equilibrium. The…
The local rotation curve of the Milky Way based on SEGUE and RAVE data
K. Sysoliatina, A. Just, O. Golubov +13
We construct the rotation curve of the Milky Way in the extended solar neighbourhood using a sample of SEGUE (Sloan Extension for Galactic Understanding and Exploration) G-dwarfs.…
Cooling jug physics
Oleh Luniachek, Ruslan Timchenko, Oleksiy Golubov
We discuss the physics of the pot-in-pot cooler. By balancing temperature decrease due to evaporation and temperature increase due to heat exchange, we find the equilibrium tempera…
Analytic model for tangential YORP
Oleksiy Golubov
The tangential YORP effect (TYORP) plays a significant role in the dynamical evolution of asteroids, and up to now has only been studied numerically. This paper describes the first…
Equilibrium rotation states of doubly synchronous binary asteroids
Oleksiy Golubov, Daniel J. Scheeres
A doubly synchronous binary asteroid simultaneously experiences YORP and BYORP, the former being independent of the radius of the orbit, while the latter linearly dependent on the…
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…
Modeling of Asteroid Shapes
Andrii Kokorev, Oleksiy Golubov
In this article we consider different methods of modeling asteroid shapes, especially lightcurve inversion technique, and scattering laws used for it. We also introduce our program…
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,…
The asymmetric drift, the local standard of rest, and implications from RAVE data
O. Golubov, A. Just, O. Bienaymé +13
The determination of the LSR is still a matter of debate. The classical value of the tangential peculiar motion of the Sun with respect to the LSR was challenged in recent years, c…
