Robotic Laser-Adaptive-Optics Imaging of 715 Kepler Exoplanet Candidates using Robo-AO [PDF]

, 2014
The Robo-AO Kepler Planetary Candidate Survey is designed to observe every Kepler planet candidate host star with laser adaptive optics imaging to search for blended nearby stars, which may be physically associated companions and/or responsible for ...

Strong Nongravitational Accelerations and the Potential for Misidentification of Near-Earth Objects

The Astrophysical Journal
Nongravitational accelerations in the absence of observed activity have recently been identified on near-Earth objects (NEOs), opening the question of the prevalence of anisotropic mass loss in the near-Earth environment.

Mathematical modeling of motion of the asteroid 99942 Apophis on the basis of Adams methods with a variable step size

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2008
: The choice of Adams methods with divided differences has been validated for solving of the equations of motion of small bodies of the Solar system. The numerical integration with a variable step size of differential equations of motion of the asteroid ...

Formation of Multiple Dynamical Classes in the Kuiper Belt via Disk Dissipation

The Astrophysical Journal
Planetesimal formation likely lasted for millions of years in the solar nebula, and the cold classicals in the Kuiper Belt are suggested to be the direct products of streaming instability.

DIGITAL ARCHIVE OF UKRVO: THE POSITIONAL ACCURACY OF MINOR PLANETS DETERMINATIONS

Odessa Astronomical Publications, 2013
Scanning and astrometric processing of two 30x30 cm photographic plates with images of minor planets were conducted. The plates were obtained at the double wide-angle astrograph (DWAA, 400/2000) on the program of photographic sky survey and the program ...

Can the Gravitational Effect of Planet X be Detected in Current-era Tracking of the Known Major and Minor Planets?

The Planetary Science Journal, 2023
Using Fisher information matrices, we forecast the uncertainties σ _M on the measurement of a “Planet X” at heliocentric distance d _X via its tidal gravitational field’s action on the known planets.
