Red or blue? A potential kilonova imprint of the delay until black hole formation following a neutron star merger

BD Metzger, R Fernández - Monthly Notices of the Royal …, 2014 - academic.oup.com
Mergers of binary neutron stars usually result in the formation of a hypermassive neutron

Fast flavor instability in hypermassive neutron star disk outflows

R Fernández, S Richers, N Mulyk, S Fahlman - Physical Review D, 2022 - APS
We examine the effect of neutrino flavor transformation by the fast flavor instability (FFI) on
long-term mass ejection from accretion disks formed after neutron star mergers. Neutrino …

Signatures of hypermassive neutron star lifetimes on r-process nucleosynthesis in the disc ejecta from neutron star mergers

J Lippuner, R Fernández, LF Roberts… - Monthly Notices of …, 2017 - academic.oup.com
