A study of the CH isomers and isotopologues: first interstellar detection of HDCCC
S. Spezzano, H. Gupta, S. Brünken +8
The partially deuterated linear isomer HDCCC of the ubiquitous cyclic carbene (-CH) was observed in the starless cores TMC-1C and L1544 at 96.9 GHz, and a confirming lin…
Vibrationally Excited CH
Andrew L. Cooksy, C. A. Gottlieb, T. C. Killian +4
Rotational spectra in four new excited vibrational levels of the linear carbon chain radical CH radical were observed in the millimeter band between 69 and 364 GHz in a low pre…
Pure rotational spectra of TiO and TiO_2 in VY Canis Majoris
T. Kaminski, C. A. Gottlieb, K. M. Menten +7
We report the first detection of pure rotational transitions of TiO and TiO_2 at (sub-)millimeter wavelengths towards the red supergiant VY CMa. A rotational temperature, T_rot, of…
Astronomical identification of CN-, the smallest observed molecular anion
M. Agundez, J. Cernicharo, M. Guelin +11
We present the first astronomical detection of a diatomic negative ion, the cyanide anion CN-, as well as quantum mechanical calculations of the excitation of this anion through co…
Detection of C5N- and vibrationally excited C6H in IRC +10216
J. Cernicharo, M. Guélin, M. Agúndez +2
We report the detection in the envelope of the C-rich star IRC +10216 of four series of lines with harmonically related frequencies: B1389, B1390, B1394 and B1401. The four series…
Search for anions in molecular sources: C4H- detection in L1527
M. Agundez, J. Cernicharo, M. Guelin +3
We present the results of a search for the negative ion C4H- in various dark clouds, low mass star-forming regions and photon-dominated regions (PDRs). We have also searched for C6…
