[ noun ] (physics,astronomy) radiation from the sun
Used in print (Cornell H. Mayer, "Radio Emission of the Moon...)The infrared_emission could then be assumed to originate at the surface of the moon , while the radio_emission originates at some depth beneath the surface , where the temperature variation due_to solar_radiation is reduced in amplitude and shifted in phase . The quiescent level of centimeter wave-length solar_radiation would increase the average disk brightness temperature by less than 1 ` K . Therefore , neglecting the extreme outbursts , reflected solar_radiation is not expected to cause sizable errors in the measurements of planetary radiation in the centimeter - and decimeter wave-length range . (J. F. Vedder, "Micrometeorites", in Francis S. J...)The Poynting-Robertson effect ( Robertson , 1937 ; Wyatt and Whipple , 1950 ) , which is a retardation of the orbital motion of particles by the relativistic aberration of the repulsive_force of the impinging solar_radiation , causes the dust to spiral into the sun in times much shorter than the age of the Earth . Whipple ( 1955 ) extends the effects to include the solar corpuscular_radiation pressure , which increases both the minimum particle size and the drag .
