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…
PSTGF : time-independent R-Matrix atomic electron-impact code
L. Fernández-Menchero, A. C. Conroy, C. P. Ballance +4
STGF is a community code employed for outer-region R-matrix calculations, describing electron-impact collisional processes. It is widely recognised that the original version of STG…
Spectroscopic diagnostics of low-ionized iron-peak elements. Electron-impact excitation of Ni and photoionisation of Ni
Luis Fernández-Menchero, Ryan T. Smyth, Catherine A. Ramsbottom +1
The spectra from Fe-peak elements may be used to determine the temperature and density of various astrophysical objects. Determination of these quantities is underpinned by the acc…
Electron-impact excitation of N using the B-spline R-matrix method: Importance of the target structure description and the size of the close-coupling expansion
L. Fernández-Menchero, O. Zatsarinny, K. Bartschat
There are major discrepancies between recent ICFT (Intermediate Coupling Frame Transformation) and DARC (Dirac Atomic R-matrix Code) calculations (Fernández-Menchero et al. 2014, A…
