Globules and Pillars in Cygnus X I. Herschel Far-infrared imaging of the Cyg OB2 environment
N. Schneider, S. Bontemps, F. Motte +21
The radiative feedback of massive stars on molecular clouds creates pillars, globules and other features at the interface between the HII region and molecular cloud. We present her…
A Herschel and BIMA study of the sequential star formation near the W48A HII region
K. L. J. Rygl, S. Goedhart, D. Polychroni +22
We present the results of Herschel HOBYS photometric mapping combined with BIMA observations and additional archival data, and perform an in-depth study of the evolutionary phases…
Ionization compression impact on dense gas distribution and star formation, Probability density functions around H ii regions as seen by Herschel
P. Tremblin, N. Schneider, V. Minier +22
Ionization feedback should impact the probability distribution function (PDF) of the column density around the ionized gas. We aim to quantify this effect and discuss its potential…
Pillars and globules at the edges of H ii regions, Confronting Herschel observations and numerical simulations
P. Tremblin, V. Minier, N. Schneider +24
Pillars and globules are present in many high-mass star-forming regions, such as the Eagle nebula (M16) and the Rosette molecular cloud, and understanding their origin will help ch…
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…
Herschel/HIFI observations of red supergiants and yellow hypergiants: I. Molecular inventory
D. Teyssier, G. Quintana-Lacaci, A. P. Marston +17
Red supergiant stars (RSGs) and yellow hypergiant stars (YHGs) are believed to be the high-mass counterparts of stars in the AGB and early post-AGB phases. We study the mass-loss i…
The spine of the swan: A Herschel study of the DR21 ridge and filaments in Cygnus X
M. Hennemann, F. Motte, N. Schneider +31
In order to characterise the cloud structures responsible for the formation of high-mass stars, we present Herschel observations of the DR21 environment. Maps of the column density…
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…
Herschel/HIFI deepens the circumstellar NH3 enigma
K. M. Menten, F. Wyrowski, J. Alcolea +23
Circumstellar envelopes (CSEs) of a variety of evolved stars have been found to contain ammonia (NH3) in amounts that exceed predictions from conventional chemical models by many o…
Herschel/HIFI observations of high-J CO transitions in the protoplanetary nebula CRL618
V. Bujarrabal, J. Alcolea, R. Soria-Ruiz +25
We performed Herschel/HIFI observations of several CO lines in the far-infrared/sub-mm in the protoplanetary nebula CRL618. The high spectral resolution provided by HIFI allows mea…
Strong CH+ J=1-0 emission and absorption in DR21
E. Falgarone, V. Ossenkopf, M. Gerin +30
We report the first detection of the ground-state rotational transition of the methylidyne cation CH+ towards the massive star-forming region DR21 with the HIFI instrument onboard…
Discovery of water vapour in the carbon star V Cygni from observations with Herschel/HIFI
D. A. Neufeld, E. González-Alfonso, G. Melnick +25
We report the discovery of water vapour toward the carbon star V Cygni. We have used Herschel's HIFI instrument, in dual beam switch mode, to observe the 1(11) - 0(00) para-water t…
HIFI spectroscopy of low-level water transitions in M82
A. Weiss, M. A. Requena-Torres, R. Guesten +23
We present observations of the rotational ortho-water ground transition, the two lowest para-water transitions, and the ground transition of ionised ortho-water in the archetypal s…
Water content and wind acceleration in the envelope around the oxygen-rich AGB star IK Tau as seen by Herschel/HIFI
L. Decin, K. Justtanont, E. De Beck +4
During their asymptotic giant branch, evolution low-mass stars lose a significant fraction of their mass through an intense wind, enriching the interstellar medium with products of…

Martin Harwit, Martin Houde, Paule Sonnentrucker +26
CONTEXT: Water vapour maser emission from evolved oxygen-rich stars remains poorly understood. Additional observations, including polarisation studies and simultaneous observation…
