The Arizona Radio Observatory 1 mm Spectral Survey of IRC +10216 and VY Canis Majoris (215–285 GHz)
A low noise (1{sigma} rms {approx} 3 mK) 1 mm spectral survey (214.5-285.5 GHz) of the oxygen-rich supergiant VY Canis Majoris and the carbon-rich asymptotic giant branch star IRC +10216 has beenExpand
CARBON CHEMISTRY IN THE ENVELOPE OF VY CANIS MAJORIS: IMPLICATIONS FOR OXYGEN-RICH EVOLVED STARS
Observations of the carbon-bearing molecules CO, HCN, CS, HNC, CN, and HCO+ have been conducted toward the circumstellar envelope of the oxygen-rich red supergiant star, VY Canis Majoris (VY CMa),Expand
Constraining Phosphorus Chemistry in Carbon- and Oxygen-Rich Circumstellar Envelopes: Observations of PN, HCP, and CP
Millimeter-wave observations of PN, CP, and HCP have been carried out toward circumstellar envelopes of evolved stars using the Arizona Radio Observatory (ARO). HCP and PN have been identified in theExpand
Identification of Phosphorus Monoxide (X 2Πr) in VY Canis Majoris: Detection of the First P-O Bond in Space
A new interstellar molecule, PO (X 2Πr), has been detected toward the envelope of the oxygen-rich supergiant star VY Canis Majoris (VY CMa) using the Submillimeter Telescope of the Arizona RadioExpand
MILLIMETER DETECTION OF AlO (X 2Σ+): METAL OXIDE CHEMISTRY IN THE ENVELOPE OF VY CANIS MAJORIS
A new circumstellar molecule, the radical AlO (X 2Σ+), has been detected toward the envelope of the oxygen-rich supergiant star VY Canis Majoris (VY CMa) using the Arizona Radio Observatory (ARO).Expand
EXOTIC METAL MOLECULES IN OXYGEN-RICH ENVELOPES: DETECTION OF AlOH (X1Σ+) IN VY CANIS MAJORIS
A new interstellar molecule, AlOH, has been detected toward the envelope of VY Canis Majoris (VY CMa), an oxygen-rich red supergiant. Three rotational transitions of AlOH were observed using theExpand
Comparative Spectra of Oxygen-rich Versus Carbon-rich Circumstellar Shells: VY Canis Majoris and IRC +10216 at 215-285 GHz
A sensitive (1σ rms at 1 MHz resolution ~3 mK) 1 mm spectral line survey (214.5-285.5 GHz) of VY Canis Majoris (VY CMa) and IRC +10216 has been conducted to compare the chemistries of oxygen- andExpand
Understanding the chemical complexity in Circumstellar Envelopes of C-Rich AGB stars: the case of IRC +10216
Abstract The circumstellar envelopes of carbon-rich AGB stars show a chemical complexity that is exemplified by the prototypical object IRC +10216, in which about 60 different molecules have beenExpand
An Extremely Large Excess of 18O in the Hydrogen-deficient Carbon Star HD 137613
We report the discovery of a uniquely large excess of 18O in the hydrogen-deficient carbon (HdC) star HD 137613 based on a spectrum of the first-overtone bands of CO at 2.3-2.4 μm in which threeExpand
Detection of C3O in IRC +10216: Oxygen-Carbon Chain Chemistry in the Outer Envelope
The oxygen-bearing species C3O has been identified in the circumstellar envelope of the carbon star IRC 10216. The , , , , and transitions were detected at 2 and 3 mm using the Arizona J p 8 r 79 rExpand
