Research of resonant motion of Apollo asteroids with inner planets
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007 We study the resonant motion of Apollo asteroids with inner planets (Venus, Earth, Mars). It is shown that 1760 among 2026 Apollo asteroids move in resonance with one, two or three inner planets.

Measuring the Orbit Drift of Near-Earth Asteroids by the Yarkovsky Effect
The Astrophysical Journal, 2023 The Yarkovsky effect causes the semimajor axis drift of near-Earth asteroids. The drift can be detected by a precise orbit determination process. Using the proposed algorithm, 2233 out of 27,078 near-Earth asteroids are chosen as the initial candidates ...

Escape of asteroids from the main belt
, 2017 Aims. We locate escape routes from the main asteroid belt, particularly into the near-Earth-object (NEO) region, and estimate the relative fluxes for different escape routes as a function of object size under the influence of the Yarkovsky semimajor-axis

Periodic motion near the surface of asteroids [PDF]
, 2015 We are interested in the periodic motion and bifurcations near the surface of an asteroid. The gravity field of an irregular asteroid and the equation of motion of a particle near the surface of an asteroid are studied.

The 3-4 $\mu$m Spectra of Jupiter Trojan Asteroids [PDF]
, 2016 To date, reflectance spectra of Jupiter Trojan asteroids have revealed no distinctive absorption features. For this reason, the surface composition of these objects remains a subject of speculation. Spectra have revealed, however, that the Jupiter Trojan

Near-Earth Asteroids as Possible Parent Bodies of Meteor Streams [PDF]
Учёные записки Казанского университета: Серия Естественные науки, 2016 The genetic relationship of meteor streams with near-Earth asteroids (NEAs) is being actively studied. A genetic link with the asteroid is possible only for streams in which meteoroids have the geocentric speed smaller than 50 km/s, thereby meaning the ...

, 2017 V-type asteroids are a taxonomic class whose surface is associated to a basaltic composition. The only known source of V-type asteroids in the Main Asteroid Belt is (4) Vesta, that is located in the inner part of the belt.

Distribution of spin-axes longitudes and shape elongations of main-belt asteroids
, 2016 Context: Large all-sky surveys provide us with a lot of photometric data that are sparse in time (typically few measurements per night) and can be potentially used for the determination of shapes and rotational states of asteroids.

Perspective Projection of an Ellipse and an Ellipsoid for Analytical View Factor Evaluation
Heat Transfer, EarlyView.ABSTRACT Radiative view factors are fundamental quantities for evaluating radiative heat transfer between different surfaces. While analytical expressions of view factors have been evaluated for various types of basic geometries, including circular disks and spheres, extending these solutions to more complex geometries, such as ellipses and ellipsoids ...
