Infrared detection of aliphatic organics on a cometary nucleus
A. Raponi, M. Ciarniello, F. Capaccioni +28
The ESA Rosetta mission has acquired unprecedented measurements of comet 67/P-Churyumov-Gerasimenko (hereafter 67P) nucleus surface, whose composition, as determined by in situ and…
Ammonium salts are a reservoir of nitrogen on a cometary nucleus and possibly on some asteroids
O. Poch, I. Istiqomah, E. Quirico +29
The measured nitrogen-to-carbon ratio in comets is lower than for the Sun, a discrepancy which could be alleviated if there is an unknown reservoir of nitrogen in comets. The nucle…
