Kleinmann-Law nebula
  میغ ِ کلاینمن-لاؤ  
miq-e Kainman-Law
Fr.: nébuleuse de Kleinmann-Law

An strong, extended infrared source in the Orion Nebula, about 1 arcminute NW of the Trapezium and about 12 arcseconds south of the → Becklin-Neugebauer object. It dominates the infrared emission at wavelengths above 20 microns. It probably represents a cluster of young and forming stars embedded in a dusty molecular cloud.

See also: Named after Douglas E. Kleinmann (1942-) and Frank J. Low (1933-), who first studied this object in 1967; → nebula.

Klotho

klotho (#)
Fr.: Klotho, Clotho

A → main belt asteroid (97) discovered by the German astronomer Ernst W. Temple in 1868 working at Marseille Observatory.

See also: Named after Klotho (literally “spinner”) the Gk. goddess of fate who spins the thread of life, from klothein “to spin.”

klystron
  کلیسترون  
klistron (#)
Fr.: klystron

An electron tube for converting direct-current energy into radio frequency energy by alternately speeding up and slowing down the electrons. It is used as a microwave amplifier or oscillator in radar and high-frequency radio work.

See also: From Gk. kluzein, klus- “to wash, break over” + -tron.
