Excitation and Recombination Data for Nd I-V with Applications to Kilonovae
N. Ferguson, L. P. Mulholland, M. McCann +2
Neodymium (Nd), a key r-process element, significantly influences the opacity and emergent spectra of kilonovae resulting from neutron star mergers. We present new atomic data for…
Recombination Rates for Uranium Ions Using the Analogous Nd III as a Guideline and Their Effect on Kilonova Nebular SpectraAn Exploration of Recombination of Uranium with application to Kilonovae Spectra
Niamh Ferguson, Anders Jerkstrand, Smaranika Banerjee +2
Dielectronic recombination (DR) is expected to be the dominant recombination process during the non-local thermodynamic equilibrium (non-LTE) phase of kilonovae, yet reliable DR da…
Infrared spectral signatures of light r-process elements in kilonovae
Anders Jerkstrand, Quentin Pognan, Smaranika Banerjee +8
A central question regarding neutron star mergers is whether they are able to produce all the r-process elements, from first to third peak. The high abundances of first-peak elemen…
Nebular spectra of kilonovae with detailed recombination rates -- I. Light r-process composition
Smaranika Banerjee, Anders Jerkstrand, Nigel Badnell +3
To investigate spectra of kilonovae in the NLTE phase (t>= 1 week), we perform atomic calculations for dielectronic recombination (DR) rates for the light r-process elements Se (Z…
