Dust of comet 67P/Churyumov-Gerasimenko collected by Rosetta/MIDAS: classification and extension to the nanometre scale

T. Mannel, M. S. Bentley, P. D. Boakes +9

The properties of the smallest subunits of cometary dust contain information on their origin and clues to the formation of planetesimals and planets. Compared to IDPs or particles…

Cross sections relevant to gamma-ray line emission in solar flares: He-induced reactions on O nuclei

V. Tatischeff, J. Duprat, J. Kiener +12

Gamma-ray production cross sections have been measured for gamma-ray lines copiously emitted in the He bombardment of O nuclei: the 937, 1042 and 1081 keV lines of $^{18…
