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…
