The M 16 molecular complex under the influence of NGC 6611. Herschel's perspective of the heating effect on the Eagle Nebula
Hill, T.; White, G. J.; Roussel, H. +25 more
We present Herschel images from the HOBYS key program of the Eagle Nebula (M 16) in the far-infrared and sub-millimetre, using the PACS and SPIRE cameras at 70 µm, 160 µm, 250 µm, 350 µm, 500 µm. M 16, home to the Pillars of Creation, is largely under the influence of the nearby NGC 6611 high-mass star cluster. The He…
The VMC survey. III. Mass-loss rates and luminosities of LMC AGB stars
van Loon, J. Th.; Gullieuszik, M.; Girardi, L. +7 more
Context. Asymptotic giant branch (AGB) stars are major contributors to both the chemical enrichment of the interstellar medium and the integrated light of galaxies. Despite its importance, the AGB is one of the least understood phases of stellar evolution. The main difficulties associated with detailed modelling of the AGB are related to the mass-…
XMM-Newton observations of SNR 1987A. II. The still increasing X-ray light curve and the properties of Fe K lines
Haberl, F.; Sturm, R.; Maggi, P. +1 more
Aims: We report on the recent observations of the supernova remnant
Methods: We analysed all X…
The 2.35 year itch of Cygnus OB2 #9. I. Optical and X-ray monitoring
Absil, O.; Damerdji, Y.; Blomme, R. +5 more
Context. Nonthermal radio emission in massive stars is expected to arise in wind-wind collisions occurring inside a binary system. One such case, the O-type star Cyg OB2 #9, was proven to be a binary only four years ago, but the orbital parameters remained uncertain. The periastron passage of 2011 was the first one to be observable under good cond…
The first X-ray survey of Galactic luminous blue variables
Nazé, Y.; Rauw, G.; Hutsemékers, D.
Aims: The X-ray emission of massive stars has been studied when these objects are in their main-sequence phase, as well as when they are in their Wolf-Rayet phase. However, the X-ray properties of the transitional luminous blue variable (LBV) phase remain unknown.
Methods: Using a dedicated but limited XMM-Newton survey and archival XMM-…
Herschel observations of a potential core-forming clump: Perseus B1-E
Bernard, J. -P.; Hill, T.; White, G. J. +17 more
We present continuum observations of the Perseus B1-E region from the Herschel Gould Belt Survey. These Herschel data reveal a loose grouping of substructures at 160-500 µm not seen in previous submillimetre observations. We measure temperature and column density from these data and select the nine densest and coolest substructures for follo…
Intracluster light in clusters of galaxies at redshifts 0.4 < z < 0.8
Ilbert, O.; Schrabback, T.; Allam, S. +27 more
Context. The study of intracluster light (ICL) can help us to understand the mechanisms taking place in galaxy clusters, and to place constraints on the cluster formation history and physical properties. However, owing to the intrinsic faintness of ICL emission, most searches and detailed studies of ICL have been limited to redshifts z < 0.4. <…
The Herschel HIFI water line survey in the low-mass proto-stellar outflow L1448
Liseau, R.; Codella, C.; van Dishoeck, E. F. +8 more
Aims: As part of the WISH (Water In Star-forming regions with Herschel) key project, systematic observations of H2O transitions in young outflows are being carried out with the aim of understanding the role of water in shock chemistry and its physical and dynamical properties. We report on the observations of several ortho- and par…
Observing planet-disk interaction in debris disks
Ertel, S.; Wolf, S.; Rodmann, J.
Context. Debris disks are commonly considered to be a by-product of planet formation. Structures in debris disks induced by planet-disk interaction are promising to provide valuable constraints on the existence and properties of embedded planets.
Aims: We investigate the observability of structures in debris disks induced by planet-disk inter…
Discovery of VHE emission towards the Carina arm region with the H.E.S.S. telescope array: HESS J1018-589
Klochkov, D.; Santangelo, A.; Quirrenbach, A. +191 more
The Carina arm region, containing the supernova remnant SNR G284.3-1.8, the high-energy (HE; E > 100 MeV) binary 1FGL J1018.6-5856 and the energetic pulsar PSR J1016-5857 and its nebula, has been observed with the H.E.S.S. telescope array. The observational coverage of the region in very-high-energy (VHE; E > 0.1 TeV) γ-rays benefits from de…
