Opacity modelling of heavy-metal hot subdwarfs. Photoionization of Sr, Y and Zr
L. Fernández-Menchero, C. S. Jeffery, C. A. Ramsbottom +1
Heavy-metal hot subdwarfs (sdB and sdO) represent a small group of stars with unusually high concentrations of trans-iron elements in their atmospheres, having abundances ~ 10000 t…
Dirac R-matrix calculations for the electron-impact excitation of neutral tungsten providing noninvasive diagnostics for magnetic confinement fusion
R. T. Smyth, C. P. Ballance, C. A. Ramsbottom +3
Neutral tungsten is the primary candidate as a wall material in the divertor region of the International Thermonuclear Experimental Reactor (ITER). The efficient operation of ITER…
Photoionization of Co and electron-impact excitation of Co using the Dirac R-matrix method
N. B. Tyndall, C. A. Ramsbottom, C. P. Ballance +1
Modelling of massive stars and supernovae (SNe) plays a crucial role in understanding galaxies. From this modelling we can derive fundamental constraints on stellar evolution, mass…
Valence and L-shell photoionization of Cl-like Argon using R-matrix techniques
Niall Tyndall, Catherine Ramsbottom, Connor Ballance +1
Photoionization cross sections are obtained using the relativistic Dirac Atomic R-matrix Codes (DARC) for all valence and L-shell energy ranges between 27-270eV. A total of 557 lev…
