Herschel imaging of the dust in the Helix Nebula (NGC 7293)
G. C. Van de Steene, P. A. M. van Hoof, K. M. Exter +19
In our series of papers presenting the Herschel imaging of evolved planetary nebulae, we present images of the dust distribution in the Helix nebula (NGC 7293). Images at 70, 160,…
A stubbornly large mass of cold dust in the ejecta of Supernova 1987A
M. Matsuura, E. Dwek, M. J. Barlow +33
We present new Herschel photometric and spectroscopic observations of Supernova 1987A, carried out in 2012. Our dedicated photometric measurements provide new 70 micron data and im…
A Far-Infrared Spectroscopic Survey of Intermediate Redshift (Ultra) Luminous Infrared Galaxies
Georgios E. Magdis, D. Rigopoulou, R. Hopwood +16
We present Herschel far-IR photometry and spectroscopy as well as ground based CO observations of an intermediate redshift (0.21 < z < 0.88) sample of Herschel-selected (ultra)-lum…
EChOSim: The Exoplanet Characterisation Observatory software simulator
E. Pascale, I. P. Waldmann, C. J. MacTavish +11
EChOSim is the end-to-end time-domain simulator of the Exoplanet Characterisation Observatory (EChO) space mission. EChOSim has been developed to assess the capability EChO has to…
Herschel observations of gas and dust in comet C/2006 W3 (Christensen) at 5 AU from the Sun
M. de Val-Borro, D. Bockelée-Morvan, E. Jehin +19
We aimed to measure the H2O and dust production rates in C/2006 W3 (Christensen) with the Herschel Space Observatory at a heliocentric distance of ~ 5 AU. We have searched for emis…
Herschel spectral-mapping of the Helix Nebula (NGC 7293): Extended CO photodissociation and OH+ emission
M. Etxaluze, J. Cernicharo, J. R. Goicoechea +13
The Helix Nebula (NGC 7293) is the closest planetary nebulae. Therefore, it is an ideal template for photochemical studies at small spatial scales in planetary nebulae. We aim to s…
