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,…
ALMA observations of alpha Centauri: First detection of main-sequence stars at 3mm wavelength
R. Liseau, W. Vlemmings, A. Bayo +19
The precise mechanisms that provide the non-radiative energy for heating the chromosphere and the corona of the Sun and those of other stars constitute an active field of research.…
Resolving the shocked gas in HH54 with Herschel: CO line mapping at high spatial and spectral resolution
P. Bjerkeli, R. Liseau, C. Brinch +11
The HH54 shock is a Herbig-Haro object, located in the nearby Chamaeleon II cloud. Observed CO line profiles are due to a complex distribution in density, temperature, velocity, an…
The detached dust shells around the carbon AGB stars R Scl and V644 Sco
Matthias Maercker, Sofia Ramstedt, Marcelo M. L. Leal-Ferreira +2
Detached shells are believed to be created during a thermal pulse, and constrain the time scales and physical properties of one of the main drivers of late stellar evolution. We ai…
Signatures of warm carbon monoxide in protoplanetary discs observed with Herschel SPIRE
M. H. D. van der Wiel, D. A. Naylor, I. Kamp +9
Molecular gas constitutes the dominant mass component of protoplanetary discs. To date, these sources have not been studied comprehensively at the longest far-infrared and shortest…
The Debris Disk of Solar Analogue Ceti: Herschel Observations and Dynamical Simulations of the Proposed Multiplanet System
S. M. Lawler, J. Di Francesco, G. M. Kennedy +16
Ceti is a nearby, mature G-type star very similar to our Sun, with a massive Kuiper Belt analogue (Greaves et al. 2004) and possible multiplanet system (Tuomi et al. 2013) that…
