IRC +10 216 in 3-D: morphology of a TP-AGB star envelope
M. Guélin, N. A. Patel, M. Bremer +10
During their late pulsating phase, AGB stars expel most of their mass in the form of massive dusty envelopes, an event that largely controls the composition of interstellar matter.…
A Molecular Spiral Arm in the Far Outer Galaxy
T. M. Dame, P. Thaddeus
We have identified a spiral arm lying beyond the Outer Arm in the first Galactic quadrant ~15 kpc from the Galactic center. After tracing the arm in existing 21 cm surveys, we sear…
An Interferometric Spectral-line Survey of IRC+10216 in the 345 GHz Band
Nimesh A. Patel, Ken H. Young, Carl A. Gottlieb +10
We report a spectral-line survey of the extreme carbon star IRC+10216 carried out between 293.9 and 354.8 GHz with the Submillimeter Array. A total of 442 lines were detected, more…
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 Vibrationally Excited CO in IRC+10216
Nimesh A. Patel, Ken H. Young, Sandra Brünken +3
Using the Submillimeter Array we have detected the J=3-2 and 2-1 rotational transitions from within the first vibrationally excited state of CO toward the extreme carbon star IRC+1…
Submillimeter narrow emission lines from the inner envelope of IRC+10216
Nimesh A. Patel, Ken H. Young, Sandra Brünken +8
A spectral-line survey of IRC+10216 in the 345 GHz band has been undertaken with the Submillimeter Array. Although not yet completed, it has already yielded a fairly large sample o…
