Polar

Polar \Po"lar\, n. (Conic Sections) The right line drawn through the two points of contact of the two tangents drawn from a given point to a given conic section. The given point is called the pole of the line. If the given point lies within the curve so that the two tangents become imaginary, there is still a real polar line which does not meet the curve, but which possesses other properties of the polar. Thus the focus and directrix are pole and polar. There are also poles and polar curves to curves of higher degree than the second, and poles and polar planes to surfaces of the second degree.

Polar

Polar \Po"lar\, a. [Cf. F. polaire. See Pole of the earth.]

  1. Of or pertaining to one of the poles of the earth, or of a sphere; situated near, or proceeding from, one of the poles; as, polar regions; polar seas; polar winds.

  2. Of or pertaining to the magnetic pole, or to the point to which the magnetic needle is directed.

  3. (Geom.) Pertaining to, reckoned from, or having a common radiating point; as, polar co["o]rdinates.

    Polar axis, that axis of an astronomical instrument, as an equatorial, which is parallel to the earths axis.

    Polar bear (Zo["o]l.), a large bear ( Ursus maritimus syn. Thalarctos maritimus) inhabiting the arctic regions. It sometimes measures nearly nine feet in length and weighs 1,600 pounds. It is partially amphibious, very powerful, and the most carnivorous of all the bears. The fur is white, tinged with yellow. Called also White bear. See Bear.

    Polar body, Polar cell, or Polar globule (Biol.), a minute cell which separates by karyokinesis from the ovum during its maturation. In the maturation of ordinary ova two polar bodies are formed, but in parthogenetic ova only one. The first polar body formed is usually larger than the second one, and often divides into two after its separation from the ovum. Each of the polar bodies removes maternal chromatin from the ovum to make room for the chromatin of the fertilizing spermatozo["o]n; but their functions are not fully understood.

    Polar circles (Astron. & Geog.), two circles, each at a distance from a pole of the earth equal to the obliquity of the ecliptic, or about 23[deg] 28', the northern called the arctic circle, and the southern the antarctic circle.

    Polar clock, a tube, containing a polarizing apparatus, turning on an axis parallel to that of the earth, and indicating the hour of the day on an hour circle, by being turned toward the plane of maximum polarization of the light of the sky, which is always 90[deg] from the sun.

    Polar co["o]rdinates. See under 3d Co["o]rdinate.

    Polar dial, a dial whose plane is parallel to a great circle passing through the poles of the earth.
    --Math. Dict.

    Polar distance, the angular distance of any point on a sphere from one of its poles, particularly of a heavenly body from the north pole of the heavens.

    Polar equation of a line or Polar equation of a surface, an equation which expresses the relation between the polar co["o]rdinates of every point of the line or surface.

    Polar forces (Physics), forces that are developed and act in pairs, with opposite tendencies or properties in the two elements, as magnetism, electricity, etc.

    Polar hare (Zo["o]l.), a large hare of Arctic America ( Lepus arcticus), which turns pure white in winter. It is probably a variety of the common European hare ( Lepus timidus).

    Polar opposition, or Polaric opposition or Polar contrast or Polaric contrast (Logic), an opposition or contrast made by the existence of two opposite conceptions which are the extremes in a species, as white and black in colors; hence, as great an opposition or contrast as possible.

    Polar projection. See under Projection.

    Polar whale (Zo["o]l.), the right whale, or bowhead. See Whale.

Polar (cataclysmic variable star)

A Polar (also AM Herculis Star) is a highly magnetic type of cataclysmic variable binary star system. Like other cataclysmic variables (CVs), polars contain two stars: an accreting white dwarf (WD), and a low-mass donor star (usually a red dwarf) which is transferring mass to the WD as a result of the WD's gravitational pull. (In technical terms, the donor star overfills its Roche lobe.) Polars are distinguished from other CVs by the presence of a very strong magnetic field in the WD. Typical magnetic field strengths of polar systems are 10 million to 80 million gauss (1000–8000 teslas). The WD in the polar AN Ursae Majoris has the strongest known magnetic field among cataclysmic variables, with a field strength of 230 million gauss (23 kT). The presence of such a strong magnetic field gives rise to a number of fundamental differences between polars and non-magnetic CVs.

Polar (TV channel)

Ciné Polar is a French television channel owned by AB Groupe.

The channel was originally only available on AB Sat and as an option on CanalSat, but is now available through a cinema contract with AB, on cable, on ADSL, and on digital television packages.

Change in cinema package :

  • At its launch in 1996, the cinema package of AB Groupe comprised five channels: Ciné Palace, Rire (comedies), Romance (sentimental films), Polar (crime and suspense films) and Action
  • Due to the repackaging of the cinema package in September 2002, the cinema package formerly known as CINEBOX now has new channels named Ciné Box, Ciné comic (formerly Rire), Ciné Polar (formerly Polar) and Ciné Fx.
  • Today, Ciné Fx and Ciné Polar are no longer available.

At the same time as this was taking place, the group purchased the cinema channel Action in 1996.

At the heart of the programming are the big names in classic films noirs, notably the first works of Alfred Hitchcock.
