Experimental oscillator strengths of Al I lines for near-infrared astrophysical spectroscopy
Madeleine Burheim, Henrik Hartman, Hampus Nilsson
Elemental abundances can be determined from stellar spectra, making it possible to study galactic formation and evolution. Accurate atomic data is essential for the reliable interp…
Lifetime measurements and oscillator strengths in singly ionised scandium and the solar abundance of scandium
A. Pehlivan Rhodin, M. T. Belmonte, L. Engstrom +8
The lifetimes of 17 even-parity levels (3d5s, 3d4d, 3d6s, and 4p) in the region 57743-77837 cm of singly ionised scandium (\ion{Sc}{ii}) were measured by two-step time-r…
Radiative data for highly excited 3d8 4d levels in Ni II from laboratory measurements and atomic calculations
H. Hartman, L. Engstrom, H. Lundberg +6
This work reports new experimental radiative lifetimes and calculated oscillator strengths for transitions from 3d8 4d levels of astrophysical interest in singly ionized nickel. Ra…
Experimental radiative lifetimes for highly excited states and calculated oscillator strengths for lines of astrophysical interest in singly ionized cobalt (Co II)
P. Quinet, V. Fivet, P. Palmeri +4
This work reports new experimental radiative lifetimes and calculated oscillator strengths for transitions of astrophysical interest in singly ionized cobalt. More precisely, ninet…
Silver and palladium help unveil the nature of a second r-process
Camilla Juul Hansen, Francesca Primas, Henrik Hartman +7
The rapid neutron-capture process, creating about half of the heaviest elements in the Solar System was believed to be unique. Many recent studies have shown that this does not inc…
Formation of Zr I and II lines under non-LTE conditions of stellar atmospheres
A. Velichko, L. Mashonkina, H. Nilsson
The non-local thermodynaic equilibrium (non-LTE) line formation for the two ions of zirconium is considered through a range of spectral types when the Zr abundance varies from the…
