New submillimetre HCN lasers in carbon-rich evolved stars
W. Yang, K. T. Wong, H. Wiesemeyer +6
Strong laser emission from hydrogen cyanide (HCN) at 805 and 891 GHz has been discovered towards carbon-rich (C-rich) AGB stars, originating from the Coriolis-coupled system betwee…
NIKA2 observations of dust grain evolution from star-forming filament to T-Tauri disk: Preliminary results from NIKA2 observations of the Taurus B211/B213 filament
Q. Nguyen-Luong, R. Adam, P. Ade +51
To understand the evolution of dust properties in molecular clouds in the course of the star formation process, we constrain the changes in the dust emissivity index from star-form…
Molecules, shocks, and disk in the axi-symmetric wind of the MS-type AGB star RS Cancri
J. M. Winters, D. T. Hoai, K. T. Wong +6
The latest evolutionary phases of low- and intermediate mass stars are characterized by complex physical processes like turbulence, convection, stellar pulsations, magnetic fields,…
Angular momentum profiles of Class 0 protostellar envelopes
M. Gaudel, A. J. Maury, A. Belloche +10
[abridged] Understanding how the infalling gas redistribute most of its initial angular momentum inherited from prestellar cores before reaching the stellar embryo is a key questio…
Properties of the dense core population in Orion B as seen by the Herschel Gould Belt survey
V. Konyves, Ph. Andre, D. Arzoumanian +15
We present a detailed study of the Orion B clouds (d~400 pc), imaged with the PACS/SPIRE cameras at 70-500 m by the Herschel Gould Belt survey (HGBS). We release new high-res. m…
NIKA2 observations around LBV stars: emission from stars and circumstellar material
J. Ricardo Rizzo, A. Ritacco, C. Bordiu
Luminous Blue Variable (LBV) stars are evolved massive objects, previous to core-collapse supernova. LBVs are characterized by photometric and spectroscopic variability, produced b…
Simultaneous 22 GHz Water and 44 GHz Methanol Masers Survey of Ultracompact HII Regions
Won-Ju Kim, Kee-Tae Kim, Kwang-Tae Kim
We have carried out a multi-epoch simultaneous survey of 22 GHz HO and 44 GHz Class I CHOH masers toward 103 ultracompact HII regions (UCHIIs) between 2010 and 2017. We det…
Convective cells in Betelgeuse: imaging through spectropolarimetry
A. López Ariste, P. Mathias, B. Tessore +7
We assess the ability to image the photosphere of red supergiants and, in particular Betelgeuse, through the modelling of the observed linear polarization in atomic spectral lines.…
A slowly expanding torus associated with the candidate LBV MGE 042.0787+00.5084
C. Bordiu, J. R. Rizzo, A. Ritacco
The luminous blue variable (LBV) phase is a poorly understood stage in the evolution of high mass stars, characterized for its brevity and instability. The surroundings of LBV star…
The convective photosphere of the red supergiant CE Tau. I. VLTI/PIONIER H-band interferometric imaging
M. Montargès, R. Norris, A. Chiavassa +3
Context. Red supergiant stars are one of the latest stages in the evolution of massive stars. Their photospheric convection may play an important role in the launching mechanism of…
Magnetic field in IRC+10216 and other C-Rich Evolved Stars
A. Duthu, F. Herpin, H. Wiesemeyer +3
During the transition from the Asymptotic Giant Branch (AGB) to Planetary Nebulae (PN), the circumstellar geometry and morphology change dramatically. Another characteristic of thi…
On the nature of the candidate T-Tauri star V501 Aurigae
M. Vaňko, G. Torres, L. Hambálek +18
We report new multi-colour photometry and high-resolution spectroscopic observations of the long-period variable V501 Aur, previously considered to be a weak-lined T-Tauri star bel…
The Spatial Distribution of Complex Organic Molecules in the L1544 Pre-stellar Core
Izaskun Jimenez-Serra, Anton I. Vasyunin, Paola Caselli +7
The detection of complex organic molecules (COMs) toward cold sources such as pre-stellar cores (with T<10 K), has challenged our understanding of the formation processes of COMs i…
Long-Term Photometry of IC 348 with the YETI Network
D. J. Fritzewski, M. Kitze, M. Mugrauer +29
We present long-term photometric observations of the young open cluster IC 348 with a baseline time-scale of 2.4 yr. Our study was conducted with several telescopes from the Young…
Temperatures of dust and gas in S~140
E. Koumpia, P. M. Harvey, V. Ossenkopf +4
In dense parts of interstellar clouds (> 10^5 cm^-3), dust & gas are expected to be in thermal equilibrium, being coupled via collisions. However, previous studies have shown that…
HOPS 383: An Outbursting Class 0 Protostar in Orion
