Astrochemistry: June 2017


Sulfur is an abundant element in the cosmos and it is thus an important contributor to astrochemistry in the interstellar medium and in the Solar System.

ALMA has observed stars like the Sun at a very early stage in their formation and found traces of methyl isocyanate -- a chemical building block of life.

Emission of fullerenes in their infrared vibrational bands has been detected in space near hot stars.

Cassini discovered a plethora of neutral and ionised molecules in Titan's ionosphere including, surprisingly, anions and negatively charged molecules extending up to 13,800 u/q. In this letter we forward model the Cassini electron spectrometer response function to this unexpected ionospheric component to achieve an increased mass resolving capability for negatively charged species observed at Titan altitudes of 950-1300 km.
