cavity kâvâk (#) Fr.: cavité 1) An apparently hollow formation in the structure of an astronomical
object, for example a sizable hole on the surface of a
→ molecular cloud created by
→ ultraviolet photons of a
→ massive star. From M.Fr. cavité, from L.L. cavitas "hollowness," from L. cavus "hollow." Kâvâk, related to verb kâvidan (kâftan) "to dig; to examine, investigate," cf. L. cavus "hollow" (E. derivatives: cavity, concave, cave, excavate), Gk. koilos "hollow," Armenian sor, PIE *kowos "hollow." |
CCD si-si-di (#) Fr.: CCD |
CCD array ârast-e sisidi Fr.: détecteur CCD bidimensionnel A CCD detector having two dimensions. |
CCD detector âškârgar-e sisidi (#) Fr.: détecteur CCD |
CCD frame tak-tasvir-e sisidi Fr.: image CCD One of a series of astronomical images obtained using a CCD detector in particular for calibration purposes. |
CCD gain bahre-ye CCD Fr.: gain de CCD In a → CCD detector, the ratio of the initial number of electrons in a → pixel to the final number of → analog-to-digital units (or counts) reported by camera software. For example, a gain of 1.8 e-/count means that the camera produces 1 count for every 1.8 recorded electrons. |
CCD shutter bastâr-e si-si-di, bastâvar-e ~ Fr.: obturateur CCD A mechanical device of a CCD camera that controls the duration of a an exposure, as by opening and closing to allow the stellar light to expose the CCD detector. Shutter, from to shut, from O.E. scyttan from W.Gmc. *skutjanan + → -er. |
CDM model negare-ye mâdde-ye sard-e târik Fr.: théorie de la matière noire froide A → cosmological model that attributes the formation of structures in the → early Universe to an exotic particle (→ cold dark matter) which was → non-relativistic at the time of → decoupling. According to this model, CDM began clumping together soon after the → Big Bang, while the → baryonic matter was still coupled with the → photons, and prevented to condense. Smaller → clumps of dark matter merged to form larger and larger clumps, and when the normal visible matter had decoupled from the photons, at the → recombination era (380,000 years after the Big Bang), it collapsed onto these dark matter clumps. In this way, the dark matter clumps acted as seeds for galaxy formation. |
ceasefire âtašbas (#) Fr.: cessez-le-feu An often temporary cessation of hostilities during wartime for a specific purpose. It may be unilateral or bilateral. From cease from O.Fr. cesser "to come to an end, stop," from L. cessare "to cease, go slow, be idle," + → fire. Âtašbas, from âtaš, → fire, + bas, from bas kardan "to stop, end; leave." |
celestial âsmâni (#) Fr.: céleste Of or relating to the sky or visible heavens. M.E., from O.Fr., from M.L. celestialis, from L. cælestis "heavenly," from cælum "heaven, sky." Âsmâni related to âsmân, → sky. |
celestial axis âse-ye âsmân (#) Fr.: axe du monde The Earth's axis extended to the → celestial pole. |
celestial body axtar (#), jesm-e âsmâni (#) Fr.: corps céleste |
celestial coordinates hamârâhâ-ye âsmâni (#) Fr.: coordonées célestes Any system of coordinates used to define a point on the celestial sphere (zenith distance, altitude, celestial latitude, celestial longitude, etc.). → celestial; → coordinates. |
celestial equator hamugâr-e âsmâni Fr.: équateur céleste An imaginary great circle on the sky half-way between the → celestial poles. It is the projection of the → equator of the Earth on the sky. |
celestial globe gu-ye âsmâni Fr.: globe céleste A small globe representing the celestial sphere, on which the apparent positions of the stars are indicated. |
celestial horizon ofoq-e âsmâni (#) Fr.: horizon céleste A great circle on the → celestial sphere having a plane that passes through the center of the Earth at a right angle to the line formed by an observer's → zenith and → nadir. |
celestial latitude varunâ-ye âsmâni Fr.: latitude céleste Angular distance → north or → south measured from the → ecliptic to a → celestial object. |
celestial longitude derežnâ-ye âsmâni Fr.: longitude céleste Angular distance to an object measured eastward along the → ecliptic from the → vernal equinox. |
celestial mechanics mekânik-e âsmâni (#) Fr.: mécanique céleste The branch of astronomy that deals with the calculation of motions of celestial bodies under the action of their mutual gravitational attractions. |
celestial meridian nimruzân-e âsmâni (#) Fr.: méridien céleste The great circle on the → celestial sphere, passing through the two → celestial poles and the observer's → zenith. |
