ALMA Observations of Ethyl Formate toward Orion KL
Yaping Peng, V. M. Rivilla, Li Zhang +2
Orion KL is one of the prime templates of astrochemical and prebiotic chemical studies. We wish to explore more organic molecules with increasing complexity in this region. In part…
Abundant Z-cyanomethanimine in the interstellar medium: paving the way to the synthesis of adenine
V. M. Rivilla, J. Martín-Pintado, I. Jiménez-Serra +6
We report the first detection in the interstellar medium of the Z-isomer of cyanomethanimine (HNCHCN), an HCN dimer proposed as precursor of adenine. We identified six transitions…
First ALMA maps of HCO, an important precursor of complex organic molecules, towards IRAS 16293-2422
V. M. Rivilla, M. T. Beltrán, A. Vasyunin +4
The formyl radical HCO has been proposed as the basic precursor of many complex organic molecules such as methanol (CHOH) or glycolaldehyde (CHOHCHO). Using ALMA, we have m…
Chasing discs around O-type (proto)stars - ALMA evidence for an SiO disc and disc wind from G17.64+0.16
L. T. Maud, R. Cesaroni, M. S. N. Kumar +28
We present high angular resolution 0.2 arcsec continuum and molecular emission line Atacama Large Millimeter/sub-millimeter Array (ALMA) observations of G17.64+0.16 in Band 6 (220G…
Protonated CO2 in massive star-forming clumps
F. Fontani, A. Vagnoli, M. Padovani +3
Interstellar CO2 is an important reservoir of carbon and oxygen, and one of the major constituents of the icy mantles of dust grains, but it is not observable directly in the cold…
The first detections of the key prebiotic molecule PO in star-forming regions
Víctor M. Rivilla, Francesco Fontani, Maite Beltrán +4
Phosphorus is a crucial element in prebiotic chemistry, especially the PO bond, which is key for the formation of the backbone of the deoxyribonucleic acid. So far, PO had only…
