New Level Resolved Ground and Excited State Pb III, IV, V & VI Photoionization Cross Sections for Heavy Metal Subdwarf Modeling
David J. Dougan, Matti Dorsch, Laura J. A. Scott +3
High abundances of various lead (Pb) species have been identified in the spectra of many Asymptotic Giant Branch (AGB) stars and O- and B-type subdwarfs (sdO/B). Additional atomic…

Strontium I, III, IV and V: Electron Impact Excitation Data for Kilonovae and White Dwarf Diagnostic Applications
David J. Dougan, Niall E. McElroy, Connor P. Ballance +1
Strontium (Sr) emissions have been observed across a wide range of astrophysical phenomena, from kilonovae (KNe) events to white dwarf (WD) stars. Precise and extensive atomic data…

Collisional and Radiative Data for Tellurium ions in Kilonovae modelling and Laboratory Benchmarks
Leo Patrick Mulholland, Fiona McNeill, Stuart A. Sim +2
Tellurium is a primary candidate for the identification of the 2.1 m emission line in kilonovae (KNe) spectra AT2017gfo and GRB230307A. Despite this, there is currently an insu…
