Hot DA white dwarf model atmosphere calculations: Including improved Ni PI cross sections
S. P. Preval, M. A. Barstow, N. R. Badnell +2
To calculate realistic models of objects with Ni in their atmospheres, accurate atomic data for the relevant ionization stages needs to be included in model atmosphere calculations…
The Tungsten Project: Dielectronic Recombination Data For Collisional-Radiative Modelling In ITER
S. P. Preval, N. R. Badnell, M. G. O'Mullane
Tungsten is an important metal in nuclear fusion reactors. It will be used in the divertor component of ITER (Latin for 'the way'). The Tungsten Project aims to calculate partial a…
Understanding the spectrum of the very hot DA white dwarf PG0948+534
S. P. Preval, M. A. Barstow
PG0948+534 is currently one of the hottest DA white dwarf stars, and is also one of the most mysterious. Attempts to model the sharp, deep absorption features of this star have bee…
Partial and Total Dielectronic Recombination rate coefficients for W73+ to W56+
S. P. Preval, N. R. Badnell, M. G. O'Mullane
Dielectronic recombination (DR) is a key atomic process which affects the spectroscopic diagnostic modelling of tungsten, most of whose ionization stages will be found somewhere in…
