Sprite "elf, fairy, eerie, ghost-like quality," so named by D. Sentman et al. (1995, Geophys. Res. Let, 22, 1205) because of the fleeting nature of sprites; M.E., from O.Fr. esprit "spirit," from L. spiritus "soul, vigor, breath," related to spirare "to breathe."

SS 433
     
SS 433

Fr.: SS 433   

A → close binary star lying at the center of the → supernova remnant W50, in → Aquila, about 18,000 → light-years away. The system consists of a normal → O star or → B star in a 13.087 day orbit around a compact object that is either a → neutron star or a → black hole. Material transferred from the normal star into an → accretion disk surrounding the compact object is ejected in two jets of ionized gas in opposite directions, at about a quarter of the speed of light. The system is also a periodic X-ray source. The jets are emitted in a cone with a half-angle of about 20°. The cone is inclined by 80° to the line of sight. The compact object precesses with a period of 164 days. This causes the projected angle of the jets to go through a 164 day cycle, giving the variation in the Doppler shifts.

Such called because this object carries number 433 in the Stephenson-Sanduleak catalog of stars with strong emission lines, compiled by Bruce Stephenson and Nicholas Sanduleak in 1977.

  ترازمندی ِ پایدار   
tarâzmandi-ye pâydâr (#)

Fr.: équilibre stable   

An equilibrium state of a system in which if a small perturbation away from equilibrium is applied, the system will return to its equilibrium state. An example is a pendulum hanging straight down.
