Herschel/HIFI observations of the circumstellar ammonia lines in IRC+10216
M. R. Schmidt, J. H. He, R. Szczerba +14
New high-resolution far-infrared (FIR) observations of both ortho- and para-NH3 transitions toward IRC+10216 were obtained with Herschel, with the goal of determining the ammonia a…
HIFISTARS Herschel/HIFI observations of VY Canis Majoris. Molecular-line inventory of the envelope around the largest known star
J. Alcolea, V. Bujarrabal, P. Planesas +16
To gain insight into the physical conditions and kinematics of the warm (100-1000 K) gas around the red hyper-giant VY CMa, we performed sensitive high spectral resolution observat…
The abundance of HCN in circumstellar envelopes of AGB stars of different chemical types
F. L. Schöier, S. Ramstedt, H. Olofsson +3
A multi-transition survey of HCN (sub-) millimeter line emission from a large sample of AGB stars of different chemical type is presented. The data are analysed and circumstellar H…
Herschel/HIFI observations of O-rich AGB stars : molecular inventory
K. Justtanont, T. Khouri, M. Maercker +15
Spectra, taken with the heterodyne instrument, HIFI, aboard the Herschel Space Observatory, of O-rich asymptotic giant branch (AGB) stars which form part of the guaranteed time key…
Herschel/HIFI observations of molecular emission in protoplanetary nebulae and young planetary nebulae
V. Bujarrabal, J. Alcolea, R. Soria-Ruiz +1
We performed Herschel/HIFI observations of intermediate-excitation molecular lines in the far-infrared/submillimeter range in a sample of ten protoplanetary nebulae and young plane…
A Pilot Imaging Line Survey of RW LMi and IK Tau Using the Expanded Very large Array
M. J Claussen, L. O. Sjouwerman, M. P. Rupen +4
We report on a pilot imaging line survey (36.0 - 37.0 GHz, with ~1 km/s spectral channels) with the Expanded Very Large Array for two asymptotic giant branch stars, RW LMi (= CIT6,…
