LOST CITY METEORITE: DETERMINATION OF THE TEMPERATURE GRADIENT INDUCED BY ATMOSPHERIC FRICTION USING THERMOLUMINESCENCE
Authors:J Eduardo Vaz
Abstract:The temperature gradient induced in the Lost City meteorite during its nine-second flight through the atmosphere has been determined from measurements of the variations in the natural TL output of the meteorite with depth below the surface of the specimen. The rate of temperature change decreases about 5 °C per mm in the range of 4 mm to 15 mm below its surface. Although temperatures above 205 °C penetrated only the outer 4 mm of the meteorite, temperatures higher than 120 °C penetrated as far as 20 mm below its surface.
