Astrochemistry: April 2019


Since the Archean, N2 has been a major atmospheric constituent in Earth's atmosphere.

Iram 30-m Observations towards eight protostellar outflow sources were taken in the 96-176 GHz range. Transitions of CH3OH and CH3CHO were detected in seven of them.

Recent advances in laboratory spectroscopy lead to the claim of ionized Buckminsterfullerene (C60+) as the carrier of two diffuse interstellar bands (DIBs) in the near-infrared.

Cyanogen (NCCN) is the simplest member of the dicyanopolyynes group, and has been proposed as a major source of the CN radical observed in cometary atmospheres. Although not detected through its rotational spectrum in the cold interstellar medium, this very stable species is supposed to be very abundant.
