barycentric coordinates
Barycentric subdivision
In mathematics, the barycentric subdivision is a standard way to subdivide a given simplex into smaller ones.
barycentric calculus
Mathematical framework for celestial mechanics.
Barycentric coordinate system
In geometry, a barycentric coordinate system is a coordinate system in which the location of a point is specified by reference to a simplex (a triangle for points in a plane, a tetrahedron for points in three-dimensional space, etc.).
Barycentric Dynamical Time
(TDB, from the French Temps Dynamique Barycentrique) a relativistic coordinate time scale, intended for astronomical use as a time standard to take account of time dilationExplanations given with (a) IAU resolutions 1991, under Resolution A.4, at 'Notes for recommendation III', and IAU 2006 resolution 3, and its footnotes; and (b) explanations and references cited at "Time dilation -- due to gravitation and motion together".
barycentric energy
The energy of a system with respect to its centre of gravity
Barycentric Coordinate Time
A coordinate time standard intended to be used as the independent variable of time for all calculations pertaining to orbits of planets, asteroids, comets, and interplanetary spacecraft in the Solar System.
Barycentric Julian Date
the Julian Date corrected for differences in the Earth's position with respect to the barycentre of the Solar System.
