Dynamicalmass estimates for the main asteroid belt and the trans-Neptunian Kuiper belt have been found from their gravitational influence on the motion of planets. Discrete rotating models consisting ofmovingmaterial points have been used tomodel the total attraction fromsmall or as yet undetected bodies of the belts. The masses of the model belts have been included in the set of parameters being refined and determined and have been obtained by processing more than 800 thousand modern… 
Estimates of the change rate of solar mass and gravitational constant based on the dynamics of the Solar System
The estimate of the change rate of the solar gravitational parameter d(GM⊙)∕dt is obtained from processing modern positional observations of planets and spacecraft. Observations were processed and

Recently, there has been some discussion in the literature about the effects of the anisotropy in the spatial density of dark matter in the Solar neighbourhood arising from the motion of the Sun
Relativistic Effects in Orbital Motion of the S-Stars at the Galactic Center
The Galactic Center star cluster, known as S-stars, is a perfect source of relativistic phenomena observations. The stars are located in the strong field of relativistic compact object Sgr A* and are
Revisiting the 2PN Pericenter Precession in View of Possible Future Measurements
At the second post-Newtonian (2PN) order, the secular pericenter precession ω ˙ 2 PN of either a full two-body system made of well-detached non-rotating monopole masses of comparable size and a
What is the Oxygen Isotope Composition of Venus? The Scientific Case for Sample Return from Earth’s “Sister” Planet
Venus is Earth’s closest planetary neighbour and both bodies are of similar size and mass. As a consequence, Venus is often described as Earth’s sister planet. But the two worlds have followed very

We numerically and analytically work out the first-order post-Newtonian (1pN) orbital effects induced on the semimajor axis a , the eccentricity e , the inclination I , the longitude of the ascending
Twentieth-century milestones in the history of the Russian ephemeris service: Marking 100 years of the Calculation Institute and astronomical yearbook
This is the history of how the Russian ephemeris service for major and minor bodies of the solar system was created and developed to provide necessary data for the needs of astronomy, as well as


Hidden Mass in the Asteroid Belt
Abstract The total mass of the asteroid belt is estimated from an analysis of the motions of the major planets by processing high precision measurements of ranging to the landers Viking-1, Viking-2,
The formation of the Kuiper belt by the outward transport of bodies during Neptune's migration
It is shown that the objects currently observed in the dynamically cold Kuiper belt were most probably formed within ∼35 au and were subsequently pushed outward by Neptune's 1:2 mean motion resonance during its final phase of migration.
The Primordial Excitation and Clearing of the Asteroid Belt
Abstract In this paper, we use N -body integrations to study the effect that planetary embryos spread between ∼0.5 and 4 AU would have on primordial asteroids. The most promising model for the
High-Precision Ephemerides of Planets—EPM and Determination of Some Astronomical Constants
The latest version of the planetary part of the numerical ephemerides EPM (Ephemerides of Planets and the Moon) developed at the Institute of Applied Astronomy of the Russian Academy of Sciences is
Thermal Evolution and Differentiation of Edgeworth-Kuiper Belt Objects
The region beyond Neptune's orbit is populated by numerous bodies with semimajor axes from 31 to 48 AU. This region, known as the Kuiper belt, should contain primitive bodies, perhaps among the most
The history of the Solar system's debris disc: observable properties of the Kuiper belt
The Nice model of Gomes et al. suggests that the migration of the giant planets caused a planetesimal clearing event, which led to the late heavy bombardment (LHB) at 880 Myr. Here, we investigate
Planet Formation in the Outer Solar System
This paper reviews coagulation models for planet formation in the Kuiper belt, emphasizing links to recent observations of our and other solar systems. At heliocentric distances of 35-50 AU,
Collisional Erosion in the Primordial Edgeworth-Kuiper Belt and the Generation of the 30-50 AU Kuiper Gap
One of the oustanding questions about the architecture of the outer solar system is how the trans-Neptunian disk of comets and small planet-scale objects known as the solar system's Edgeworth-Kuiper
Accretion in the Early Kuiper Belt II. Fragmentation
We describe new planetesimal accretion calculations in the Kuiper Belt that include fragmentation and velocity evolution. All models produce two power law cumulative size distributions, NC ∝ r −2.5
Updated IAA RAS planetary ephemerides-EPM2011 and their use in scientific research
The EPM (Ephemerides of Planets and the Moon) numerical ephemerides were first created in the 1970s in support of Russian space flight missions and since then have been constantly improved at IAA
