  2. Barycentric coordinate system - Wikipedia

    en.wikipedia.org/wiki/Barycentric_coordinate_system

    A 3-simplex, with barycentric subdivisions of 1-faces (edges) 2-faces (triangles) and 3-faces (body). 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.).

  3. Barycenter (astronomy) - Wikipedia

    en.wikipedia.org/wiki/Barycenter_(astronomy)

    m 1 and m 2 are the masses of the two bodies. The semi-major axis of the secondary's orbit, r 2, is given by r 2 = a − r 1. When the barycenter is located within the more massive body, that body will appear to "wobble" rather than to follow a discernible orbit.

  4. Center of mass - Wikipedia

    en.wikipedia.org/wiki/Center_of_mass

    Let the percentage of the total mass divided between these two particles vary from 100% P 1 and 0% P 2 through 50% P 1 and 50% P 2 to 0% P 1 and 100% P 2, then the center of mass R moves along the line from P 1 to P 2. The percentages of mass at each point can be viewed as projective coordinates of the point R on this line, and are termed ...

  5. Barycentric - Wikipedia

    en.wikipedia.org/wiki/Barycentric

    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

  6. Gell-Mann–Nishijima formula - Wikipedia

    en.wikipedia.org/wiki/Gell-Mann–Nishijima_formula

    It was originally given by Kazuhiko Nishijima and Tadao Nakano in 1953, [1] and led to the proposal of strangeness as a concept, which Nishijima originally called "eta-charge" after the eta meson. [2] Murray Gell-Mann proposed the formula independently in 1956. [3] The modern version of the formula relates all flavour quantum numbers (isospin ...

  7. Orbital state vectors - Wikipedia

    en.wikipedia.org/wiki/Orbital_state_vectors

    [2]: 24 Many other reference frames can be used to meet various application requirements, including those centered on the Sun or on other planets or moons, the one defined by the barycenter and total angular momentum of the solar system (in particular the ICRF ), or even a spacecraft's own orbital plane and angular momentum.

  8. Barycentric and geocentric celestial reference systems

    en.wikipedia.org/wiki/Barycentric_and_geocentric...

    The barycentric celestial reference system (BCRS) is a coordinate system used in astrometry to specify the location and motions of astronomical objects. It was created in 2000 by the International Astronomical Union (IAU) to be the global standard reference system for objects located outside the gravitational vicinity of Earth: [1] planets, moons, and other Solar System bodies, stars and other ...

  9. Two-body problem - Wikipedia

    en.wikipedia.org/wiki/Two-body_problem

    [2] Let x 1 and x 2 be the vector positions of the two bodies, and m 1 and m 2 be their masses. The goal is to determine the trajectories x 1 (t) and x 2 (t) for all times t, given the initial positions x 1 (t = 0) and x 2 (t = 0) and the initial velocities v 1 (t = 0) and v 2 (t = 0). When applied to the two masses, Newton's second law states that
