Volatile Species in Comet 67P/Churyumov-Gerasimenko: Investigating the Link from the ISM to the Terrestrial Planets
Drozdovskaya, Maria N.; Rubin, Martin; Wampfler, Susanne F. +2 more
Comets contain abundant amounts of organic and inorganic species. Many of the volatile molecules in comets have also been observed in the interstellar medium and some of them even with similar relative abundances, indicating formation under similar conditions or even sharing a common chemical pathway. There is a growing amount of evidence that sug…
CHO-Bearing Molecules in Comet 67P/Churyumov-Gerasimenko
De Keyser, Johan; Gombosi, Tamas I.; Berthelier, Jean-Jacques +10 more
In 2004, the Rosetta spacecraft was sent to comet 67P/Churyumov-Gerasimenko for the first ever long-term investigation of a comet. After its arrival in 2014, the spacecraft spent more than two years in immediate proximity to the comet. During these two years, the ROSINA Double Focusing Mass Spectrometer (DFMS) onboard Rosetta discovered a coma wit…
Astrochemistry as a Tool To Follow Protostellar Evolution: The Class I Stage
Bianchi, Eleonora; Ceccarelli, Cecilia; Codella, Claudio +3 more
The latest developments in astrochemistry have shown how some molecular species can be used as a tool to study the early stages of the solar-type star formation process. Among them, the more relevant species are the interstellar complex organic molecules (iCOMs) and the deuterated molecules. Their analysis give us information on the present and pa…
