Barycentric

In astronomy,

• Barycenter or barycentre, the center of mass of two or more bodies that orbit each other
• Barycentric coordinates, coordinates defined by the common center of mass of two or more bodies (see Barycenter)
• Barycentric Coordinate Time, a coordinate time standard in the Solar System
• Barycentric Dynamical Time, a former time standard in the Solar System

In geometry,

• Barycentric subdivision, a way of dividing a simplicial complex
• Barycentric coordinates (mathematics), coordinates defined by the vertices of a simplex

In numerical analysis,

• Barycentric interpolation formula, a way of interpolating a polynomial through a set of given data points using barycentric weights.
