Gravitomagnetism and the Earth-Mercury range

, 2011
We numerically work out the impact of the general relativistic Lense-Thirring effect on the Earth-Mercury range caused by the gravitomagnetic field of the rotating Sun.

Long-term Variations in the Orbital Period of Hot Jupiters from Transit-timing Analysis Using TESS Survey Data

The Astrophysical Journal Supplement Series
Many hot Jupiters may experience orbital decays, which are manifested as long-term transit-timing variations. We have analyzed 7068 transits from the Transiting Exoplanet Survey Satellite (TESS) for a sample of 326 hot Jupiters.

THE ELEMENTS OF THE BASIC PHOTOMETRICAL CIRCLES ON THE SURFACE OF THE SPHERICAL PLANET AND DETERMINATION OF THEIR PLANETOCENTRIC POSITIONS

Odessa Astronomical Publications, 2016
Formulae for determination of planetocentric positions of the basic photometrical circles on the surface of the spherical planet (the equator of intensity, an orthographic limb and orthographic terminator) from the elements of these circles specified to ...

Constraining f(T) gravity in the Solar System

, 2015
In the framework of $f(T)$ theories of gravity, we solve the field equations for $f(T)=T+\alpha T^{n}$, in the weak-field approximation and for spherical symmetry spacetime.

Research on the Autonomous Orbit Determination of Beidou-3 Assisted by Satellite Laser Ranging Technology

Remote Sensing
The Beidou Global System (BDS-3) innovatively achieves autonomous navigation using inter-satellite links (ISL) across the entire constellation, but it still faces challenges such as the limitations of the prior constraint orbital accuracy and the overall

4. Ephemerides [PDF]

Transactions of the International Astronomical Union, 1979
This Report is compiled by using the reports of the Directors of the national ephemeris offices reviewing the programs for the preparation and publication of astronomical ephemerides of variuos purposes, i.e. for astronomers and space scientists, marine and air navigators, and surveyors. Some proposals of Commission members are also included.

Testing theories of gravity with planetary ephemerides

Living Reviews in Relativity
We describe here how planetary ephemerides are built in the framework of General Relativity and how they can be used to test alternative theories. We focus on the definition of the reference frame (space and time) in which the planetary ephemeris is ...
