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…
