Fr.: binaire mou
In → stellar dynamics studies of → three-body encounters, a → binary system whose → binding energy is smaller than the typical → kinetic energy of the relative motion of an incoming third body. See also → hard binary.
soft gamma repeater (SGR)
bâzgaršgar-e gâmmâ-ye narm
Fr.: répéteur gamma mou
A member of a small class of objects which emit intense bursts of → gamma rays and → X-rays (> 100 keV) at irregular intervals. The bursts last for some 100 milli-seconds. It is conjectured that they are → magnetars. See also → starquake.
soft gamma-ray repeater (SGR)
bâzgaršgar-e partowhâ-ye gâmmâ-ye narm
Fr.: répéteur des rayons gamma mous
Same as → soft gamma repeater (SGR).
Fr.: fer doux
Soft X-ray Transient (SXT)
gozarâ-ye partow-e X-e narm
An → X-ray binary system that has a long period of → quiescence interrupted by → outbursts of low-energy → soft X-rays. Alternatively known as X-ray novae, the majority (~ 75%) of SXTs contain a → black hole and a low-mass → main sequence → companion star in orbit around one another. It is thought that SXTs arise in a similar manner to → dwarf novae, through instabilities in the → accretion disk around the → compact object (→ disk instability model).
partowhâ-ye iks-e narm
Fr.: rayons X mous
X-ray photons with energies between about 0.1 to 10 keV. → hard X-rays.
A general term used to describe a collection of computer programs, procedures, and documentation that perform some tasks on a computer system. → hardware.
→ soft + ware, from M.E., from O.E. waru, from P.Gmc. *waro (cf. Swed. vara, Dan. vare, M.Du. were, Du. waar, Ger. Ware "goods").
Narm, → soft + afzâr "instrument, means, tool," from Mid.Pers. afzâr, abzâr, awzâr "instrument, means," Proto-Iranian *abi-cāra- or *upa-cāra-, from cāra-, cf. Av. cārā- "instrument, device, means" (Mid.Pers. câr, cârag "means, remedy;" loaned into Arm. aucar, aucan "instrument, remedy;" Mod.Pers. câré "remedy, cure, help"), from kar- "to do, make, build;" kərənaoiti "he makes" (Pers. kardan, kard- "to do, to make"); cf. Skt. kr- "to do, to make," krnoti "he makes, he does," karoti "he makes, he does," karma "act, deed;" PIE base kwer- "to do, to make").
Fr.: architecture de logiciel
The overall structure of a software system consisting of mutually dependent components that create a logical whole.
Fr.: logiciel utilitaire
