  2. Equipotential - Wikipedia

    en.wikipedia.org/wiki/Equipotential

    An equipotential of a scalar potential function in n-dimensional space is typically an (n − 1)-dimensional space. The del operator illustrates the relationship between a vector field and its associated scalar potential field. An equipotential region might be referred as being 'of equipotential' or simply be called 'an equipotential'.

  3. Roche lobe - Wikipedia

    en.wikipedia.org/wiki/Roche_lobe

    This critical equipotential defines the Roche lobes. [2] Where matter moves relative to the co-rotating frame it will seem to be acted upon by a Coriolis force. This is not derivable from the Roche lobe model as the Coriolis force is a non-conservative force (i.e. not representable by a scalar potential).

  4. Common envelope - Wikipedia

    en.wikipedia.org/wiki/Common_envelope

    Cataclysmic variables, X-ray binaries and systems of close double white dwarfs or neutron stars are examples of systems of this type which can be explained as having undergone common envelope evolution. In all these examples there is a compact remnant (a white dwarf, neutron star or black hole) which must have been the core of a star which was ...

  5. External ray - Wikipedia

    en.wikipedia.org/wiki/External_ray

    An external ray is a curve that runs from infinity toward a Julia or Mandelbrot set. [1] Although this curve is only rarely a half-line (ray) it is called a ray because it is an image of a ray. External rays are used in complex analysis , particularly in complex dynamics and geometric function theory .

  6. Topological string theory - Wikipedia

    en.wikipedia.org/wiki/Topological_string_theory

    The A-model and B-model on two mirror manifolds are related by mirror symmetry, which has been described as a T-duality on a three-torus. The A-model and B-model on the same manifold are conjectured to be related by S-duality , which implies the existence of several new branes, called NS branes by analogy with the NS5-brane , which wrap the ...

  7. Electric potential - Wikipedia

    en.wikipedia.org/wiki/Electric_potential

    Electric potential of separate positive and negative point charges shown as color range from magenta (+), through yellow (0), to cyan (−). Circular contours are equipotential lines. Electric field lines leave the positive charge and enter the negative charge.

  9. Ten-rays model - Wikipedia

    en.wikipedia.org/wiki/Ten-rays_model

    For the mathematical modeling of the propagation of ten rays, One has in account a side view and this starts off modeling the two first rays (line by sight and his respective reflection), Considering that antennas have different heights, Then , and they have a direct distance d that separates the two antennas; The first ray is formed applying Pitágoras theorem:
