Observations of the Quadrantid meteor shower from 2008 to 2012: orbits and emission spectra

摘要

The activity of the Quadrantids in January during several years (2008, 2010,2011 and 2012) has been investigated in the framework of the SPanish MeteorNetwork (SPMN). For this purpose, an array of high-sensitivity CCD videodevices and CCD all-sky cameras have been used to obtain multi-stationobservations of these meteors. These allowed us to obtain precise radiant andorbital information about this meteoroid stream. This paper presents a largeset of orbital data (namely, 85 orbits) of Quadrantid meteoroids. Most meteorsproduced by these particles were recorded during the activity peak of thisshower. Besides, we discuss four Quadrantid emission spectra. The tensilestrength of Quadrantid meteoroids has been also obtained.
