Neutron capture reactions in R process

We've investigated the impact of neutron capture rates of individual isotopes on weak r process element production and the impact of optical model potential correlations on abundance uncertainties! [1].

Equation of state dependence on priors

Investigated the impact of NS properties assumption and EoS framework on the inferred EoS. We find huge impact on the inferred EoS from both these sources! [2].
