Remote infrared observations of parent volatiles in comets: A window on the early solar system

Dello Russo, N.; Mumma, M. J.; DiSanti, M. A. +3 more

Organic volatiles and water in Oort Cloud comets were investigated at infrared wavelengths. The detected species include H ₂O, CO, CH ₃OH, CH ₄, C ₂H ₂, C ₂H ₆, OCS, HCN, NH ₃, and H ₂CO. Several daughter fragments (CN, OH, NH ₂, etc.) are…

Comparative study of the dust emission of 19P/Borrelly (Deep space 1) and 1P/Halley

Soderblom, L. A.; Thomas, N.; Ho, T. M. +2 more

Images obtained by the Miniature Integrated Camera and Imaging Spectrometer (MICAS) experiment onboard the Deep Space 1 spacecraft which encountered comet 19P/Borrelly on September 22nd 2001 show a dust coma dominated by jets. In particular a major collimated dust jet on the sunward side of the nucleus was observed. Our approach to analyse these f…
