Grid of Model Spectra for [WC] CSPNe

From Keller et al. 2011

logggrid

Fig. 1 Grid points in the logT-logg plane. The evolutionary tracks of Miller Bertolami and Althaus (2006) are also shown (continuous lines) for CSPNe with 0.5, 0.6, and 0.9 M, from right to left.


Each point shown in figure 1 is identified by a label which corresponds to a group of models with approximately the same temperature, surface gravity, and radius, but with a range of mass-loss rates and terminal wind velocities, as can be seen in the tables below. There, the models are identified by approximated values of the parameters. Precise values are available at each model page, accessible through the links in the tables, along with the calculated detailed spectrum (900 - 50000Å) and continuum (which covers the whole range of wavelength where the flux is above ~5x10-4 Jy and includes some dieletronic lines). The spectrum and continuum files are named obs_fin and obs_cont, respectively, according to the nomenclature used by CMFGEN (Hillier and Miller 1998). The files contain a list of frequencies (in 1015 Hz) and then list the corresponding fluxes in Janskies assuming a distance of 1kpc. Tables listing the ions included in the calculations of each model and the number of levels and superlevels adopted are also available in the links within the tables below.




Track A

The following table lists the models that belong to the evolutionary track for CSPNe with 0.5 M, which we refer to as track A. Information about the models and the calculated spectra can be accessed trough the links in the table. Plots comparing different models are available at the 'preview' links.

The grid models have XNe=0.02 by mass. The letters 'a' and 'b' next to some model names are two different links to additional models  that differ only in neon abundance. Models indicated by 'a' have XNe=XNe and models indicated by 'b' have XNe=0.01 by mass.







Track C

The following table lists the models that belong to the evolutionary track for CSPNe with 0.9 M, which we refer to as track C. Information about the models and the calculated spectra can be accessed trough the links in the table. Plots comparing different models are available at the 'preview' links.
