Discovery of Fulminic Acid, HCNO, in Dark Clouds
N. Marcelino, J. Cernicharo, B. Tercero +1
We report on the first detection in space of fulminic acid, HCNO. This isomer of HNCO has been observed in three starless cores, B1, L1544 and L183, and in the low mass star formin…
Rotational spectrum of deuterated and 15N ethyl cyanides: CH3CHDCN and CH2DCH2CN and of CH3CH2C15N
Laurent Margulès, Roman Motiyenko, Karine Demyk +7
Ethyl cyanide is an abundant molecule in hot molecular clouds. Lines from 13C isotopically substituted ethyl cyanide were identified in Orion. To enable the search and the possible…
Star Formation in the Trifid Nebula
B. Lefloch, J. Cernicharo, J. R. Pardo
We have obtained maps of the 1.25mm thermal dust emission and the molecular gas emission over a region of 20' by 10' arcmin around the Trifid Nebula (M20), with the IRAM 30m and th…
Solving radiative transfer with line overlaps using Gauss Seidel algorithms
F. Daniel, J. Cernicharo
The improvement in observational facilities requires refining the modelling of the geometrical structures of astrophysical objects. Nevertheless, for complex problems such as line…
Tentative detection of phosphine in IRC+10216
M. Agúndez, J. Cernicharo, J. R. Pardo +2
The J,K = 1,0-0,0 rotational transition of phosphine (PH3) at 267 GHz has been tentatively identified with a T_MB = 40 mK spectral line observed with the IRAM 30-m telescope in the…
Formation of simple organic molecules in inner T Tauri disks
Marcelino Agundez, Jose Cernicharo, Javier R. Goicoechea
We present time dependent chemical models for a dense and warm O-rich gas exposed to a strong far ultraviolet field aiming at exploring the formation of simple organic molecules in…
