However, there had been noobservational evidence to support this hypothesis until recently. Thus we conducted spectroscopicobservations of the 2001 Leonid meteor shower by using intensified HDTV cameras equipped witha reflective grating which covers 300-700 nm wavelength range. In order to minimize the effect ofair extinction near 300 nm, the observations were performed at a high elevation, i.e., the SubaruTelescope Hawaii observatory (h=4,100 m) and Nobeyama Radio Observatory (h=1,340 m) ofNational Astronomical Observatory of Japan. Spectral features of hydroxyl radicals in the cometarymeteoroids were clearly observed. In this paper, we show the first result of detection of OH emissionfrom the ground and discuss on the origin of the discovered OH A-X (0,0) band., 資料番号: SA4647206000}, pages = {149--157}, title = {UV video spectroscopy of Leonid fireballs and persistent trains}, volume = {15}, year = {2003} }
