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…
Evolution of the central stars of young planetary nebulae
Marcin Hajduk, Peter A. M. van Hoof, Albert A. Zijlstra
The evolution of central stars of planetary nebulae was so far documented in just a few cases. However, spectra collected a few decades ago may provide a good reference for studyin…
Implications of Coronal Line Emission in NGC 4696
M. Chatzikos, R. J. R. Williams, G. J. Ferland +7
We announce a new facility in the spectral code CLOUDY that enables tracking the evolution of a cooling parcel of gas with time. For gas cooling from temperatures relevant to galax…
The Very Fast Evolution of the VLTP Object V4334 Sgr
P. A. M. van Hoof, S. Kimeswenger, G. C. Van de Steene +3
V4334 Sgr (Sakurai's object) is an enigmatic evolved star that underwent a very late thermal pulse a few years before its discovery in 1996. It ejected a new, hydrogen-deficient ne…
A Far-Infrared Spectral Sequence of Galaxies: Trends and Models
Jacqueline Fischer, N. P. Abel, E. González-Alfonso +3
We present a framework for the interpretation of the far-infrared spectra of galaxies in which we have expanded the model parameters compared with previous work by varying the ioni…
Accurate determination of the free-free Gaunt factor; I - non-relativistic Gaunt factors
P. A. M. van Hoof, R. J. R. Williams, K. Volk +5
Modern spectral synthesis codes need the thermally averaged free-free Gaunt factor defined over a very wide range of parameter space in order to produce an accurate prediction for…
