More Information
Summary:Thermoluminescence, tracks of VH nuclei, and cosmogenic radionuclides with various half-lives were studied of the recently fallen Bukhara CV3 and Kilabo LL6 chondrites. The obtained experimental information and theoretical modeling were utilized to examine the thermal impact and exposure histories of these chondrites, estimate the sizes and masses they had before entering the atmosphere, extent of their ablation, the circumferences of the orbits, and to evaluate the distribution and variations in cosmic radiation in the heliosphere in the maximum phase of the 23rd solar cycle. The Kilabo LL6 chondrite and the Bensour LL6 (which fall six months earlier) were determined to be genetically related to the asteroid 3628 Boznemcova.
