Evidence for neutron capture in heavy-metal hot subdwarfs: Far-UV spectroscopy of EC22536-5304 and LSIV-14 116
M. Dorsch, C. S. Jeffery, J. Deprince +8
Most hot subdwarfs (sdO/B) are low-mass core-helium-burning stars formed through binary interaction. A subgroup of intermediate He-rich sdOBs shows extreme heavy-metal (Z>30) enric…
Study of thorium in hypersonic gas jets: Ionization potentials of Th and Th
A. Claessens, F. Ivandikov, M. Brasseur +10
Laser ionization spectroscopy was performed on both neutral and singly ionized Th with the aim of identifying the nuclear-clock isomer in the singly charged ionic state of…
Kilonova ejecta opacity inferred from new large-scale HFR atomic calculations in all elements between Ca (Z = 20) and Lr (Z = 103)
Jérôme Deprince, Gururaj Wagle, Sirine Ben Nasr +7
In the context of kilonova (KN) modeling, the present work focusses on large-scale atomic data and opacity computations for all heavy elements from Ca to Lr, with a special effort…
3D NLTE modelling of Y and Eu. Centre-to-limb variation and solar abundances
N. Storm, P. S. Barklem, S. A. Yakovleva +6
Context. Abundances of s- and r-process elements in Sun-like stars constrain nucleosynthesis in extreme astrophysical events, such as compact binary mergers and explosions of highl…
First discovery of trans-iron elements in a DAO-type white dwarf (BD)
L. Löbling, M. A. Maney, T. Rauch +4
We have identified 484 lines of the trans-iron elements (TIEs) Zn, Ga, Ge, Se, Br, Kr, Sr, Zr, Mo, In, Te, I, Xe, and Ba, for the first time in the ultraviolet spectrum of a DAO-ty…
HD 65949: Rosetta Stone or Red Herring
C. R. Cowley, S. Hubrig, P. Palmeri +5
HD 65949 is a late B star with exceptionally strong Hg II at 3984[A], but it is not a typical HgMn star. The Re II spectrum is of extraordinary strength. Abundances, or upper limit…
