Neither perpendicular nor horizontal; having the axis not perpendicular to the base; slanting; sloping.
From M.Fr. oblique, from L. obliquus "slanting, sidelong, indirect," from ob "against" + root of licinus "(of an ox whose corn tips are) bent upward," from PIE base *lei- "to bend, be movable."
Yekvar, literally "slantingn to a side," from yek-, → one, + var "side," variant bar "side; breadth; breast" (Mid.Pers. var "breast;" Av. vouru "wide, broad, extended" (vourucašāni- "looking far"), related to varah- "breast;" cf. Skt. urú- "wide, broad," úras- "breast;" Gk. eurus "wide, broad;" PIE base uer-, ueru-s"wide, broad").
oblique rotator model
model-e carxande-ye yekvar
Fr.: modèle de rotateur oblique
A stellar model in which the rotation axis is tilted relative to the magnetic dipole axis. As the star rotates, observable quantities (e.g. the line-of-sight component of the magnetic field, stellar brightness, emission lines) are modulated according to the rotational period. Such a model was first put forward by D. Stibbs (1950, MNRAS, 110, 395).
Fr.: choc oblique
Fr.: sphère oblique
The celestial sphere when the circles parallel to the equator are cut obliquely by the horizon plane, which divides them into two unequal parts. In other words, the sphere when its axis is oblique to the horizon of the place.
