We report on the detection of hot CO2 in the O-rich AGB star R Leo based on high spectral resolution observations in the range 12.8 - 14.3 μm carried out with the Echelon-cross-Echelle Spectrograph (EXES) mounted on the Stratospheric Observatory for Infrared Astronomy (SOFIA). We have found ≃ 240 CO2 emission lines in several vibrational bands. These detections were possible thanks to a favorable Doppler shift that allowed us to avoid contamination by telluric CO2 features. The highest… Expand

CONFIRMATION OF CIRCUMSTELLAR PHOSPHINE
Phosphine (PH3) was tentatively identified a few years ago in the carbon star envelopes IRC +10216 and CRL 2688 from observations of an emission line at 266.9 GHz attributable to the J = 1-0Expand
A Detailed Analysis of the Dust Formation Zone of IRC +10216 Derived from Mid-Infrared Bands of C2H2 and HCN
A spectral survey of IRC+10216 has been carried out in the range 11 to 14 � m with a spectral resolution of about 4 km s −1 . We have identified a forest of lines in six bands of C2H2 involving theExpand
The abundance of HCN in circumstellar envelopes of AGB stars of different chemical type
Aims. A multi-transition survey of HCN (sub-) millimeter line emission from a large sample of asymptotic giant branch (AGB) stars of different chemical type is presented. The data are analysed andExpand
Circumstellar acetylene in the infrared spectrum of IRC +10° 216
A THICK, expanding envelope of dust and gas surrounds the unusual object IRC +10° 216. Microwave studies have identified numerous molecular constituents of the envelope1, and the thermal infraredExpand
Carbon and oxygen isotopic ratios for nearby miras
C and O isotopic ratios are reported for a sample of 46 Mira and SRa-type variable AGB stars. Vibration-rotation 1st and 2nd overtone CO lines in 1.5 to 2.5 $\mu$m spectra were measured to deriveExpand
A λ2 mm molecular line survey of the C-star envelope IRC+10216
The mm-wave spectrum of the C-star envelope IRC+10216 has been continuously surveyed between 129.0 and 172.5 GHz with the IRAM 30-m telescope. 380 lines are detected, of which 317 have been identied.Expand
Infrared spectroscopy of Mira variables. II. R Leonis, the H/sub 2/O vibration-rotation bands
High-resolution (..delta..sigmaapprox. =0.15 cm/sup -1/) infrared spectra in the 4000--6700 cm/sup -1/ region of the bright Mira variable R Leonis have been searched for stellar water bands. ThreeExpand
The Spitzer spectroscopic survey of S-type stars
Context. S-type AGB stars are thought to be in the transitional phase between M-type and C-type AGB stars. Because the composition of the circumstellar environment reflects the photosphericExpand
SPITZER SPECTROSCOPY OF MASS LOSS AND DUST PRODUCTION BY EVOLVED STARS IN GLOBULAR CLUSTERS
We have observed a sample of 35 long-period variables (LPVs) and four Cepheid variables in the vicinity of 23 Galactic globular clusters using the Infrared Spectrograph on the Spitzer SpaceExpand
Warm water vapor envelope in Mira variables and its effects on the apparent size from the near-infrared to the mid-infrared
We present a possible interpretation for the increase of the angular diameter of the Mira variables o Cet, R Leo, and χ Cyg from the K band to the 11 µm region revealed by the recent interferometricExpand
